(** * UseAuto: Theory and Practice of Automation in Coq Proofs *) (* $Date: 2013-07-17 16:19:11 -0400 (Wed, 17 Jul 2013) $ *) (* Chapter maintained by Arthur Chargueraud *) (** In a machine-checked proof, every single detail has to be justified. This can result in huge proof scripts. Fortunately, Coq comes with a proof-search mechanism and with several decision procedures that enable the system to automatically synthesize simple pieces of proof. Automation is very powerful when set up appropriately. The purpose of this chapter is to explain the basics of working of automation. The chapter is organized in two parts. The first part focuses on a general mechanism called "proof search." In short, proof search consists in naively trying to apply lemmas and assumptions in all possible ways. The second part describes "decision procedures", which are tactics that are very good at solving proof obligations that fall in some particular fragment of the logic of Coq. Many of the examples used in this chapter consist of small lemmas that have been made up to illustrate particular aspects of automation. These examples are completely independent from the rest of the Software Foundations course. This chapter also contains some bigger examples which are used to explain how to use automation in realistic proofs. These examples are taken from other chapters of the course (mostly from STLC), and the proofs that we present make use of the tactics from the library [LibTactics.v], which is presented in the chapter [UseTactics]. *) Require Import LibTactics. (* ####################################################### *) (** * Basic Features of Proof Search *) (** The idea of proof search is to replace a sequence of tactics applying lemmas and assumptions with a call to a single tactic, for example [auto]. This form of proof automation saves a lot of effort. It typically leads to much shorter proof scripts, and to scripts that are typically more robust to change. If one makes a little change to a definition, a proof that exploits automation probably won't need to be modified at all. Of course, using too much automation is a bad idea. When a proof script no longer records the main arguments of a proof, it becomes difficult to fix it when it gets broken after a change in a definition. Overall, a reasonable use of automation is generally a big win, as it saves a lot of time both in building proof scripts and in subsequently maintaining those proof scripts. *) (* ####################################################### *) (** ** Strength of Proof Search *) (** We are going to study four proof-search tactics: [auto], [eauto], [iauto] and [jauto]. The tactics [auto] and [eauto] are builtin in Coq. The tactic [iauto] is a shorthand for the builtin tactic [try solve [intuition eauto]]. The tactic [jauto] is defined in the library [LibTactics], and simply performs some preprocessing of the goal before calling [eauto]. The goal of this chapter is to explain the general principles of proof search and to give rule of thumbs for guessing which of the four tactics mentioned above is best suited for solving a given goal. Proof search is a compromise between efficiency and expressiveness, that is, a tradeoff between how complex goals the tactic can solve and how much time the tactic requires for terminating. The tactic [auto] builds proofs only by using the basic tactics [reflexivity], [assumption], and [apply]. The tactic [eauto] can also exploit [eapply]. The tactic [jauto] extends [eauto] by being able to open conjunctions and existentials that occur in the context. The tactic [iauto] is able to deal with conjunctions, disjunctions, and negation in a quite clever way; however it is not able to open existentials from the context. Also, [iauto] usually becomes very slow when the goal involves several disjunctions. Note that proof search tactics never perform any rewriting step (tactics [rewrite], [subst]), nor any case analysis on an arbitrary data structure or predicate (tactics [destruct] and [inversion]), nor any proof by induction (tactic [induction]). So, proof search is really intended to automate the final steps from the various branches of a proof. It is not able to discover the overall structure of a proof. *) (* ####################################################### *) (** ** Basics *) (** The tactic [auto] is able to solve a goal that can be proved using a sequence of [intros], [apply], [assumption], and [reflexivity]. Two examples follow. The first one shows the ability for [auto] to call [reflexivity] at any time. In fact, calling [reflexivity] is always the first thing that [auto] tries to do. *) Lemma solving_by_reflexivity : 2 + 3 = 5. Proof. auto. Qed. (** The second example illustrates a proof where a sequence of two calls to [apply] are needed. The goal is to prove that if [Q n] implies [P n] for any [n] and if [Q n] holds for any [n], then [P 2] holds. *) Lemma solving_by_apply : forall (P Q : nat->Prop), (forall n, Q n -> P n) -> (forall n, Q n) -> P 2. Proof. auto. Qed. (** We can ask [auto] to tell us what proof it came up with, by invoking [info_auto] in place of [auto]. *) Lemma solving_by_apply' : forall (P Q : nat->Prop), (forall n, Q n -> P n) -> (forall n, Q n) -> P 2. Proof. info_auto. Qed. (* The output is: [intro P; intro Q; intro H;] *) (* followed with [intro H0; simple apply H; simple apply H0]. *) (* i.e., the sequence [intros P Q H H0; apply H; apply H0]. *) (** The tactic [auto] can invoke [apply] but not [eapply]. So, [auto] cannot exploit lemmas whose instantiation cannot be directly deduced from the proof goal. To exploit such lemmas, one needs to invoke the tactic [eauto], which is able to call [eapply]. In the following example, the first hypothesis asserts that [P n] is true when [Q m] is true for some [m], and the goal is to prove that [Q 1] implies [P 2]. This implication follows direction from the hypothesis by instantiating [m] as the value [1]. The following proof script shows that [eauto] successfully solves the goal, whereas [auto] is not able to do so. *) Lemma solving_by_eapply : forall (P Q : nat->Prop), (forall n m, Q m -> P n) -> Q 1 -> P 2. Proof. auto. eauto. Qed. (** Remark: Again, we can use [info_eauto] to see what proof [eauto] comes up with. *) (* ####################################################### *) (** ** Conjunctions *) (** So far, we've seen that [eauto] is stronger than [auto] in the sense that it can deal with [eapply]. In the same way, we are going to see how [jauto] and [iauto] are stronger than [auto] and [eauto] in the sense that they provide better support for conjunctions. *) (** The tactics [auto] and [eauto] can prove a goal of the form [F /\ F'], where [F] and [F'] are two propositions, as soon as both [F] and [F'] can be proved in the current context. An example follows. *) Lemma solving_conj_goal : forall (P : nat->Prop) (F : Prop), (forall n, P n) -> F -> F /\ P 2. Proof. auto. Qed. (** However, when an assumption is a conjunction, [auto] and [eauto] are not able to exploit this conjunction. It can be quite surprising at first that [eauto] can prove very complex goals but that it fails to prove that [F /\ F'] implies [F]. The tactics [iauto] and [jauto] are able to decompose conjunctions from the context. Here is an example. *) Lemma solving_conj_hyp : forall (F F' : Prop), F /\ F' -> F. Proof. auto. eauto. jauto. (* or [iauto] *) Qed. (** The tactic [jauto] is implemented by first calling a pre-processing tactic called [jauto_set], and then calling [eauto]. So, to understand how [jauto] works, one can directly call the tactic [jauto_set]. *) Lemma solving_conj_hyp' : forall (F F' : Prop), F /\ F' -> F. Proof. intros. jauto_set. eauto. Qed. (** Next is a more involved goal that can be solved by [iauto] and [jauto]. *) Lemma solving_conj_more : forall (P Q R : nat->Prop) (F : Prop), (F /\ (forall n m, (Q m /\ R n) -> P n)) -> (F -> R 2) -> Q 1 -> P 2 /\ F. Proof. jauto. (* or [iauto] *) Qed. (** The strategy of [iauto] and [jauto] is to run a global analysis of the top-level conjunctions, and then call [eauto]. For this reason, those tactics are not good at dealing with conjunctions that occur as the conclusion of some universally quantified hypothesis. The following example illustrates a general weakness of Coq proof search mechanisms. *) Lemma solving_conj_hyp_forall : forall (P Q : nat->Prop), (forall n, P n /\ Q n) -> P 2. Proof. auto. eauto. iauto. jauto. (* Nothing works, so we have to do some of the work by hand *) intros. destruct (H 2). auto. Qed. (** This situation is slightly disappointing, since automation is able to prove the following goal, which is very similar. The only difference is that the universal quantification has been distributed over the conjunction. *) Lemma solved_by_jauto : forall (P Q : nat->Prop) (F : Prop), (forall n, P n) /\ (forall n, Q n) -> P 2. Proof. jauto. (* or [iauto] *) Qed. (* ####################################################### *) (** ** Disjunctions *) (** The tactics [auto] and [eauto] can handle disjunctions that occur in the goal. *) Lemma solving_disj_goal : forall (F F' : Prop), F -> F \/ F'. Proof. auto. Qed. (** However, only [iauto] is able to automate reasoning on the disjunctions that appear in the context. For example, [iauto] can prove that [F \/ F'] entails [F' \/ F]. *) Lemma solving_disj_hyp : forall (F F' : Prop), F \/ F' -> F' \/ F. Proof. auto. eauto. jauto. iauto. Qed. (** More generally, [iauto] can deal with complex combinations of conjunctions, disjunctions, and negations. Here is an example. *) Lemma solving_tauto : forall (F1 F2 F3 : Prop), ((~F1 /\ F3) \/ (F2 /\ ~F3)) -> (F2 -> F1) -> (F2 -> F3) -> ~F2. Proof. iauto. Qed. (** However, the ability of [iauto] to automatically perform a case analysis on disjunctions comes with a downside: [iauto] may be very slow. If the context involves several hypotheses with disjunctions, [iauto] typically generates an exponential number of subgoals on which [eauto] is called. One major advantage of [jauto] compared with [iauto] is that it never spends time performing this kind of case analyses. *) (* ####################################################### *) (** ** Existentials *) (** The tactics [eauto], [iauto], and [jauto] can prove goals whose conclusion is an existential. For example, if the goal is [exists x, f x], the tactic [eauto] introduces an existential variable, say [?25], in place of [x]. The remaining goal is [f ?25], and [eauto] tries to solve this goal, allowing itself to instantiate [?25] with any appropriate value. For example, if an assumption [f 2] is available, then the variable [?25] gets instantiated with [2] and the goal is solved, as shown below. *) Lemma solving_exists_goal : forall (f : nat->Prop), f 2 -> exists x, f x. Proof. auto. (* observe that [auto] does not deal with existentials, *) eauto. (* whereas [eauto], [iauto] and [jauto] solve the goal *) Qed. (** A major strength of [jauto] over the other proof search tactics is that it is able to exploit the existentially-quantified hypotheses, i.e., those of the form [exists x, P]. *) Lemma solving_exists_hyp : forall (f g : nat->Prop), (forall x, f x -> g x) -> (exists a, f a) -> (exists a, g a).

(* ####################################################### *) (** ** Negation *) (** The tactics [auto] and [eauto] suffer from some limitations with respect to the manipulation of negations, mostly related to the fact that negation, written [~ P], is defined as [P -> False] but that the unfolding of this definition is not performed automatically. Consider the following example. *) Lemma negation_study_1 : forall (P : nat->Prop), P 0 -> (forall x, ~ P x) -> False. Proof. intros P H0 HX. eauto. (* It fails to see that [HX] applies *) unfold not in *. eauto. Qed. (** For this reason, the tactics [iauto] and [jauto] systematically invoke [unfold not in *] as part of their pre-processing. So, they are able to solve the previous goal right away. *) Lemma negation_study_2 : forall (P : nat->Prop), P 0 -> (forall x, ~ P x) -> False. Proof. jauto. (* or [iauto] *) Qed. (** We will come back later on to the behavior of proof search with respect to the unfolding of definitions. *) (* ####################################################### *) (** ** Equalities *) (** Coq's proof-search feature is not good at exploiting equalities. It can do very basic operations, like exploiting reflexivity and symmetry, but that's about it. Here is a simple example that [auto] can solve, by first calling [symmetry] and then applying the hypothesis. *) Lemma equality_by_auto : forall (f g : nat->Prop), (forall x, f x = g x) -> g 2 = f 2. Proof. auto. Qed. (** To automate more advanced reasoning on equalities, one should rather try to use the tactic [congruence], which is presented at the end of this chapter in the "Decision Procedures" section. *) (* ####################################################### *) (** * How Proof Search Works *) (* ####################################################### *) (** ** Search Depth *) (** The tactic [auto] works as follows. It first tries to call [reflexivity] and [assumption]. If one of these calls solves the goal, the job is done. Otherwise [auto] tries to apply the most recently introduced assumption that can be applied to the goal without producing and error. This application produces subgoals. There are two possible cases. If the sugboals produced can be solved by a recursive call to [auto], then the job is done. Otherwise, if this application produces at least one subgoal that [auto] cannot solve, then [auto] starts over by trying to apply the second most recently introduced assumption. It continues in a similar fashion until it finds a proof or until no assumption remains to be tried. It is very important to have a clear idea of the backtracking process involved in the execution of the [auto] tactic; otherwise its behavior can be quite puzzling. For example, [auto] is not able to solve the following triviality. *) Lemma search_depth_0 : True /\ True /\ True /\ True /\ True /\ True. Proof. auto. Abort. (** The reason [auto] fails to solve the goal is because there are too many conjunctions. If there had been only five of them, [auto] would have successfully solved the proof, but six is too many. The tactic [auto] limits the number of lemmas and hypotheses that can be applied in a proof, so as to ensure that the proof search eventually terminates. By default, the maximal number of steps is five. One can specify a different bound, writing for example [auto 6] to search for a proof involving at most six steps. For example, [auto 6] would solve the previous lemma. (Similarly, one can invoke [eauto 6] or [intuition eauto 6].) The argument [n] of [auto n] is called the "search depth." The tactic [auto] is simply defined as a shorthand for [auto 5]. The behavior of [auto n] can be summarized as follows. It first tries to solve the goal using [reflexivity] and [assumption]. If this fails, it tries to apply a hypothesis (or a lemma that has been registered in the hint database), and this application produces a number of sugoals. The tactic [auto (n-1)] is then called on each of those subgoals. If all the subgoals are solved, the job is completed, otherwise [auto n] tries to apply a different hypothesis. During the process, [auto n] calls [auto (n-1)], which in turn might call [auto (n-2)], and so on. The tactic [auto 0] only tries [reflexivity] and [assumption], and does not try to apply any lemma. Overall, this means that when the maximal number of steps allowed has been exceeded, the [auto] tactic stops searching and backtracks to try and investigate other paths. *) (** The following lemma admits a unique proof that involves exactly three steps. So, [auto n] proves this goal iff [n] is greater than three. *) Lemma search_depth_1 : forall (P : nat->Prop), P 0 -> (P 0 -> P 1) -> (P 1 -> P 2) -> (P 2). Proof. auto 0. (* does not find the proof *) auto 1. (* does not find the proof *) auto 2. (* does not find the proof *) auto 3. (* finds the proof *) (* more generally, [auto n] solves the goal if [n >= 3] *) Qed. (** We can generalize the example by introducing an assumption asserting that [P k] is derivable from [P (k-1)] for all [k], and keep the assumption [P 0]. The tactic [auto], which is the same as [auto 5], is able to derive [P k] for all values of [k] less than 5. For example, it can prove [P 4]. *) Lemma search_depth_3 : forall (P : nat->Prop), (* Hypothesis H1: *) (P 0) -> (* Hypothesis H2: *) (forall k, P (k-1) -> P k) -> (* Goal: *) (P 4). Proof. auto. Qed.

Proof. auto. auto 6. Qed. (** Because [auto] looks for proofs at a limited depth, there are cases where [auto] can prove a goal [F] and can prove a goal [F'] but cannot prove [F /\ F']. In the following example, [auto] can prove [P 4] but it is not able to prove [P 4 /\ P 4], because the splitting of the conjunction consumes one proof step. To prove the conjunction, one needs to increase the search depth, using at least [auto 6]. *) Lemma search_depth_5 : forall (P : nat->Prop), (* Hypothesis H1: *) (P 0) -> (* Hypothesis H2: *) (forall k, P (k-1) -> P k) -> (* Goal: *) (P 4 /\ P 4). Proof. auto. auto 6. Qed. (* ####################################################### *) (** ** Backtracking *) (** In the previous section, we have considered proofs where at each step there was a unique assumption that [auto] could apply. In general, [auto] can have several choices at every step. The strategy of [auto] consists of trying all of the possibilities (using a depth-first search exploration). To illustrate how automation works, we are going to extend the previous example with an additional assumption asserting that [P k] is also derivable from [P (k+1)]. Adding this hypothesis offers a new possibility that [auto] could consider at every step. There exists a special command that one can use for tracing all the steps that proof-search considers. To view such a trace, one should write [debug eauto]. (For some reason, the command [debug auto] does not exist, so we have to use the command [debug eauto] instead.) *) Lemma working_of_auto_1 : forall (P : nat->Prop), (* Hypothesis H1: *) (P 0) -> (* Hypothesis H2: *) (forall k, P (k+1) -> P k) -> (* Hypothesis H3: *) (forall k, P (k-1) -> P k) -> (* Goal: *) (P 2). (* Uncomment "debug" in the following line to see the debug trace: *) Proof. intros P H1 H2 H3. (* debug *) eauto. Qed. (** The output message produced by [debug eauto] is as follows. << depth=5 depth=4 apply H3 depth=3 apply H3 depth=3 exact H1 >> The depth indicates the value of [n] with which [eauto n] is called. The tactics shown in the message indicate that the first thing that [eauto] has tried to do is to apply [H3]. The effect of applying [H3] is to replace the goal [P 2] with the goal [P 1]. Then, again, [H3] has been applied, changing the goal [P 1] into [P 0]. At that point, the goal was exactly the hypothesis [H1]. It seems that [eauto] was quite lucky there, as it never even tried to use the hypothesis [H2] at any time. The reason is that [auto] always tries to use the most recently introduced hypothesis first, and [H3] is a more recent hypothesis than [H2] in the goal. So, let's permute the hypotheses [H2] and [H3] and see what happens. *) Lemma working_of_auto_2 : forall (P : nat->Prop), (* Hypothesis H1: *) (P 0) -> (* Hypothesis H3: *) (forall k, P (k-1) -> P k) -> (* Hypothesis H2: *) (forall k, P (k+1) -> P k) -> (* Goal: *) (P 2). Proof. intros P H1 H3 H2. (* debug *) eauto. Qed. (** This time, the output message suggests that the proof search investigates many possibilities. Replacing [debug eauto] with [info_eauto], we observe that the proof that [eauto] comes up with is actually not the simplest one. [apply H2; apply H3; apply H3; apply H3; exact H1] This proof goes through the proof obligation [P 3], even though it is not any useful. The following tree drawing describes all the goals that automation has been through. << |5||4||3||2||1||0| -- below, tabulation indicates the depth [P 2] -> [P 3] -> [P 4] -> [P 5] -> [P 6] -> [P 7] -> [P 5] -> [P 4] -> [P 5] -> [P 3] --> [P 3] -> [P 4] -> [P 5] -> [P 3] -> [P 2] -> [P 3] -> [P 1] -> [P 2] -> [P 3] -> [P 4] -> [P 5] -> [P 3] -> [P 2] -> [P 3] -> [P 1] -> [P 1] -> [P 2] -> [P 3] -> [P 1] -> [P 0] -> !! Done !! >> The first few lines read as follows. To prove [P 2], [eauto 5] has first tried to apply [H2], producing the subgoal [P 3]. To solve it, [eauto 4] has tried again to apply [H2], producing the goal [P 4]. Similarly, the search goes through [P 5], [P 6] and [P 7]. When reaching [P 7], the tactic [eauto 0] is called but as it is not allowed to try and apply any lemma, it fails. So, we come back to the goal [P 6], and try this time to apply hypothesis [H3], producing the subgoal [P 5]. Here again, [eauto 0] fails to solve this goal. The process goes on and on, until backtracking to [P 3] and trying to apply [H2] three times in a row, going through [P 2] and [P 1] and [P 0]. This search tree explains why [eauto] came up with a proof starting with [apply H2]. *) (* ####################################################### *) (** ** Adding Hints *) (** By default, [auto] (and [eauto]) only tries to apply the hypotheses that appear in the proof context. There are two possibilities for telling [auto] to exploit a lemma that have been proved previously: either adding the lemma as an assumption just before calling [auto], or adding the lemma as a hint, so that it can be used by every calls to [auto]. The first possibility is useful to have [auto] exploit a lemma that only serves at this particular point. To add the lemma as hypothesis, one can type [generalize mylemma; intros], or simply [lets: mylemma] (the latter requires [LibTactics.v]). The second possibility is useful for lemmas that need to be exploited several times. The syntax for adding a lemma as a hint is [Hint Resolve mylemma]. For example, the lemma asserting than any number is less than or equal to itself, [forall x, x <= x], called [Le.le_refl] in the Coq standard library, can be added as a hint as follows. *) Hint Resolve Le.le_refl. (** A convenient shorthand for adding all the constructors of an inductive datatype as hints is the command [Hint Constructors mydatatype]. Warning: some lemmas, such as transitivity results, should not be added as hints as they would very badly affect the performance of proof search. The description of this problem and the presentation of a general work-around for transitivity lemmas appear further on. *) (* ####################################################### *) (** ** Integration of Automation in Tactics *) (** The library "LibTactics" introduces a convenient feature for invoking automation after calling a tactic. In short, it suffices to add the symbol star ([*]) to the name of a tactic. For example, [apply* H] is equivalent to [apply H; auto_star], where [auto_star] is a tactic that can be defined as needed. By default, [auto_star] first tries to solve the goal using [auto], and if this does not succeed then it tries to call [jauto]. Even though [jauto] is strictly stronger than [auto], it makes sense to call [auto] first: when [auto] succeeds it may save a lot of time, and when [auto] fails to prove the goal, it fails very quickly. The definition of [auto_star], which determines the meaning of the star symbol, can be modified whenever needed. Simply write: Ltac auto_star ::= a_new_definition. ]] Observe the use of [::=] instead of [:=], which indicates that the tactic is being rebound to a new definition. So, the default definition is as follows. *) Ltac auto_star ::= try solve [ auto | jauto ]. (** Nearly all standard Coq tactics and all the tactics from "LibTactics" can be called with a star symbol. For example, one can invoke [subst*], [destruct* H], [inverts* H], [lets* I: H x], [specializes* H x], and so on... There are two notable exceptions. The tactic [auto*] is just another name for the tactic [auto_star]. And the tactic [apply* H] calls [eapply H] (or the more powerful [applys H] if needed), and then calls [auto_star]. Note that there is no [eapply* H] tactic, use [apply* H] instead. *) (** In large developments, it can be convenient to use two degrees of automation. Typically, one would use a fast tactic, like [auto], and a slower but more powerful tactic, like [jauto]. To allow for a smooth coexistence of the two form of automation, [LibTactics.v] also defines a "tilde" version of tactics, like [apply~ H], [destruct~ H], [subst~], [auto~] and so on. The meaning of the tilde symbol is described by the [auto_tilde] tactic, whose default implementation is [auto]. *) Ltac auto_tilde ::= auto. (** In the examples that follow, only [auto_star] is needed. *) (* ####################################################### *) (** * Examples of Use of Automation *) (** Let's see how to use proof search in practice on the main theorems of the "Software Foundations" course, proving in particular results such as determinism, preservation and progress. *) (* ####################################################### *) (** ** Determinism *) Module DeterministicImp.

Using automation is about rethinking the organization of sequences of tactics so as to minimize the effort involved in writing and maintaining the proof. This process is eased by the use of the tactics from [LibTactics.v]. So, before trying to optimize the way automation is used, let's first rewrite the proof of determinism: - use [introv H] instead of [intros x H], - use [gen x] instead of [generalize dependent x], - use [inverts H] instead of [inversion H; subst], - use [tryfalse] to handle contradictions, and get rid of the cases where [beval st b1 = true] and [beval st b1 = false] both appear in the context, - stop using [ceval_cases] to label subcases. *) Theorem ceval_deterministic'': forall c st st1 st2, c / st || st1 -> c / st || st2 -> st1 = st2.

In general, to make proof search run reasonably fast, one should avoid using a depth search greater than 5 or 6. Moreover, one should try to minimize the number of applicable lemmas, and usually put first the hypotheses whose proof usefully instantiates the existential variables. In fact, the ability for [eauto] to solve certain goals actually depends on the order in which the hypotheses are stated. This point is illustrated through the following example, in which [P] is a predicate on natural numbers. This predicate is such that [P n] holds for any [n] as soon as [P m] holds for at least one [m] different from zero. The goal is to prove that [P 2] implies [P 1]. When the hypothesis about [P] is stated in the form [forall n m, P m -> m <> 0 -> P n], then [eauto] works. However, with [forall n m, m <> 0 -> P m -> P n], the tactic [eauto] fails. *) Lemma order_matters_1 : forall (P : nat->Prop), (forall n m, P m -> m <> 0 -> P n) -> P 2 -> P 1. Proof. eauto.

So, it is likely that [eauto] comes up with the right one. On the other hand, guessing a value of [m] for which [m <> 0] and then checking that [P m] holds does not work well, because there are many values of [m] that satisfy [m <> 0] but not [P m]. *) (* ####################################################### *) (** ** Unfolding of Definitions During Proof-Search *) (** The use of intermediate definitions is generally encouraged in a formal development as it usually leads to more concise and more readable statements.

This section introduces a few techniques for avoiding to manually unfold definitions before calling proof search. *) (** To illustrate the treatment of definitions, let [P] be an abstract predicate on natural numbers, and let [myFact] be a definition denoting the proposition [P x] holds for any [x] less than or equal to 3. *) Axiom P : nat -> Prop.

The typical example is that of transitivity results. This section describes the problem and presents a general workaround.

Because we cannot remove hints once we've added them, we are going to open a "Section," so as to restrict the scope of the transitivity hint to that section. *) Section HintsTransitivity. Hint Resolve subtype_trans. (** Now, consider the goal [forall S T, subtype S T], which clearly has no hope of being solved.

(** Note that after closing the section, the hint [subtype_trans] is no longer active. *) End HintsTransitivity. (** In the previous example, the proof search has spent a lot of time trying to apply transitivity and reflexivity in every possible way. Its process can be summarized as follows. The first goal is [subtype S T]. Since reflexivity does not apply, [eauto] invokes transitivity, which produces two subgoals, [subtype S ?X] and [subtype ?X T]. Solving the first subgoal, [subtype S ?X], is straightforward, it suffices to apply reflexivity. This unifies [?X] with [S]. So, the second sugoal, [subtype ?X T], becomes [subtype S T], which is exactly what we started from... The problem with the transitivity lemma is that it is applicable to any goal concluding on a subtyping relation. Because of this, [eauto] keeps trying to apply it even though it most often doesn't help to solve the goal. So, one should never add a transitivity lemma as a hint for proof search. *) (** There is a general workaround for having automation to exploit transitivity lemmas without giving up on efficiency. This workaround relies on a powerful mechanism called "external hint." This mechanism allows to manually describe the condition under which a particular lemma should be tried out during proof search. For the case of transitivity of subtyping, we are going to tell Coq to try and apply the transitivity lemma on a goal of the form [subtype S U] only when the proof context already contains an assumption either of the form [subtype S T] or of the form [subtype T U]. In other words, we only apply the transitivity lemma when there is some evidence that this application might help. To set up this "external hint," one has to write the following. *) Hint Extern 1 (subtype ?S ?U) => match goal with | H: subtype S ?T |- _ => apply (@subtype_trans S T U) | H: subtype ?T U |- _ => apply (@subtype_trans S T U) end. (** This hint declaration can be understood as follows. - "Hint Extern" introduces the hint. - The number "1" corresponds to a priority for proof search. It doesn't matter so much what priority is used in practice. - The pattern [subtype ?S ?U] describes the kind of goal on which the pattern should apply. The question marks are used to indicate that the variables [?S] and [?U] should be bound to some value in the rest of the hint description. - The construction [match goal with ... end] tries to recognize patterns in the goal, or in the proof context, or both. - The first pattern is [H: subtype S ?T |- _]. It indices that the context should contain an hypothesis [H] of type [subtype S ?T], where [S] has to be the same as in the goal, and where [?T] can have any value. - The symbol [|- _] at the end of [H: subtype S ?T |- _] indicates that we do not impose further condition on how the proof obligation has to look like. - The branch [=> apply (@subtype_trans S T U)] that follows indicates that if the goal has the form [subtype S U] and if there exists an hypothesis of the form [subtype S T], then we should try and apply transitivity lemma instantiated on the arguments [S], [T] and [U]. (Note: the symbol [@] in front of [subtype_trans] is only actually needed when the "Implicit Arguments" feature is activated.) - The other branch, which corresponds to an hypothesis of the form [H: subtype ?T U] is symmetrical. Note: the same external hint can be reused for any other transitive relation, simply by renaming [subtype] into the name of that relation. *) (** Let us see an example illustrating how the hint works. *) Lemma transitivity_workaround_1 : forall T1 T2 T3 T4, subtype T1 T2 -> subtype T2 T3 -> subtype T3 T4 -> subtype T1 T4.

However, its support for disjunction can make it exponentially slow. - [jauto] extends [eauto] with support for negation, conjunctions, and existential at the head of hypothesis. - [congruence] helps reasoning about equalities and inequalities. - [omega] proves arithmetic goals with equalities and inequalities, but it does not support multiplication. - [ring] proves arithmetic goals with multiplications, but does not support inequalities. In order to set up automation appropriately, keep in mind the following rule of thumbs: - automation is all about balance: not enough automation makes proofs not very robust on change, whereas too much automation makes proofs very hard to fix when they break. - if a lemma is not goal directed (i.e., some of its variables do not occur in its conclusion), then the premises need to be ordered in such a way that proving the first premises maximizes the chances of correctly instantiating the variables that do not occur in the conclusion. - a lemma whose conclusion is [False] should only be added as a local hint, i.e., as a hint within the current section. - a transitivity lemma should never be considered as hint; if automation of transitivity reasoning is really necessary, an [Extern Hint] needs to be set up. - a definition usually needs to be accompanied with a [Hint Unfold]. Becoming a master in the black art of automation certainly requires some investment, however this investment will pay off very quickly. *)
