Cvc5ProofRule and Cvc5ProofRewriteRule

Enum Cvc5ProofRule captures the reasoning steps performed by the SAT solver, the theory solvers and the preprocessor. It represents the inference rules used to derive conclusions within a proof.

Enum Cvc5ProofRewriteRule pertains to rewrites performed on terms. These identifiers are arguments of the proof rules CVC5_PROOF_RULE_THEORY_REWRITE and CVC5_PROOF_RULE_DSL_REWRITE.

enum Cvc5ProofRule

An enumeration for proof rules. This enumeration is analogous to Kind for Node objects.

All proof rules are given as inference rules, presented in the following form:

\[\texttt{RULENAME}: \inferruleSC{\varphi_1 \dots \varphi_n \mid t_1 \dots t_m}{\psi}{if $C$}\]

where we call \(\varphi_i\) its premises or children, \(t_i\) its arguments, \(\psi\) its conclusion, and \(C\) its side condition. Alternatively, we can write the application of a proof rule as (RULENAME F1 ... Fn :args t1 ... tm), omitting the conclusion (since it can be uniquely determined from premises and arguments). Note that premises are sometimes given as proofs, i.e., application of proof rules, instead of formulas. This abuses the notation to see proof rule applications and their conclusions interchangeably.

Conceptually, the following proof rules form a calculus whose target user is the Node-level theory solvers. This means that the rules below are designed to reason about, among other things, common operations on Node objects like Rewriter::rewrite or Node::substitute. It is intended to be translated or printed in other formats.

The following ProofRule values include core rules and those categorized by theory, including the theory of equality.

The “core rules” include two distinguished rules which have special status: (1) ASSUME, which represents an open leaf in a proof; and (2) SCOPE, which encloses a scope (a subproof) with a set of scoped assumptions. The core rules additionally correspond to generic operations that are done internally on nodes, e.g., calling Rewriter::rewrite().

Rules with prefix MACRO_ are those that can be defined in terms of other rules. These exist for convenience and can be replaced by their definition in post-processing.

Values:

enumerator CVC5_PROOF_RULE_ASSUME

Assumption (a leaf)

\[\inferrule{- \mid F}{F}\]

This rule has special status, in that an application of assume is an open leaf in a proof that is not (yet) justified. An assume leaf is analogous to a free variable in a term, where we say “F is a free assumption in proof P” if it contains an application of F that is not bound by SCOPE (see below).

enumerator CVC5_PROOF_RULE_SCOPE

Scope (a binder for assumptions)

\[\inferruleSC{F \mid F_1 \dots F_n}{(F_1 \land \dots \land F_n) \Rightarrow F}{if $F\neq\bot$} \textrm{ or } \inferruleSC{F \mid F_1 \dots F_n}{\neg (F_1 \land \dots \land F_n)}{if $F=\bot$}\]

This rule has a dual purpose with ASSUME. It is a way to close assumptions in a proof. We require that \(F_1 \dots F_n\) are free assumptions in P and say that \(F_1 \dots F_n\) are not free in (SCOPE P). In other words, they are bound by this application. For example, the proof node: (SCOPE (ASSUME F) :args F) has the conclusion \(F \Rightarrow F\) and has no free assumptions. More generally, a proof with no free assumptions always concludes a valid formula.

enumerator CVC5_PROOF_RULE_SUBS

Builtin theory – Substitution

\[\inferrule{F_1 \dots F_n \mid t, ids?}{t = t \circ \sigma_{ids}(F_n) \circ \cdots \circ \sigma_{ids}(F_1)}\]

where \(\sigma_{ids}(F_i)\) are substitutions, which notice are applied in reverse order. Notice that \(ids\) is a MethodId identifier, which determines how to convert the formulas \(F_1 \dots F_n\) into substitutions. It is an optional argument, where by default the premises are equalities of the form (= x y) and converted into substitutions \(x\mapsto y\).

enumerator CVC5_PROOF_RULE_MACRO_REWRITE

Builtin theory – Rewrite

\[\inferrule{- \mid t, idr}{t = \texttt{rewrite}_{idr}(t)}\]

where \(idr\) is a MethodId identifier, which determines the kind of rewriter to apply, e.g. Rewriter::rewrite.

enumerator CVC5_PROOF_RULE_EVALUATE

Builtin theory – Evaluate

\[\inferrule{- \mid t}{t = \texttt{evaluate}(t)}\]

where \(\texttt{evaluate}\) is implemented by calling the method \(\texttt{Evalutor::evaluate}\) in theory/evaluator.h with an empty substitution. Note this is equivalent to: (REWRITE t MethodId::RW_EVALUATE).

enumerator CVC5_PROOF_RULE_ACI_NORM

Builtin theory – associative/commutative/idempotency/identity normalization

\[\inferrule{- \mid t = s}{t = s}\]

where \(\texttt{expr::isACNorm(t, s)} = \top\). For details, see expr/nary_term_util.h. This method normalizes currently based on two kinds of operators: (1) those that are associative, commutative, idempotent, and have an identity element (examples are or, and, bvand), (2) those that are associative and have an identity element (examples are str.++, re.++).

enumerator CVC5_PROOF_RULE_MACRO_SR_EQ_INTRO

Builtin theory – Substitution + Rewriting equality introduction

In this rule, we provide a term \(t\) and conclude that it is equal to its rewritten form under a (proven) substitution.

\[\inferrule{F_1 \dots F_n \mid t, (ids (ida (idr)?)?)?}{t = \texttt{rewrite}_{idr}(t \circ \sigma_{ids, ida}(F_n) \circ \cdots \circ \sigma_{ids, ida}(F_1))}\]

In other words, from the point of view of Skolem forms, this rule transforms \(t\) to \(t'\) by standard substitution + rewriting.

The arguments \(ids\), \(ida\) and \(idr\) are optional and specify the identifier of the substitution, the substitution application and rewriter respectively to be used. For details, see theory/builtin/proof_checker.h.

enumerator CVC5_PROOF_RULE_MACRO_SR_PRED_INTRO

Builtin theory – Substitution + Rewriting predicate introduction

In this rule, we provide a formula \(F\) and conclude it, under the condition that it rewrites to true under a proven substitution.

\[\inferrule{F_1 \dots F_n \mid F, (ids (ida (idr)?)?)?}{F}\]

where \(\texttt{rewrite}_{idr}(F \circ \sigma_{ids, ida}(F_n) \circ \cdots \circ \sigma_{ids, ida}(F_1)) = \top\) and \(ids\) and \(idr\) are method identifiers.

More generally, this rule also holds when \(\texttt{Rewriter::rewrite}(\texttt{toOriginal}(F')) = \top\) where \(F'\) is the result of the left hand side of the equality above. Here, notice that we apply rewriting on the original form of \(F'\), meaning that this rule may conclude an \(F\) whose Skolem form is justified by the definition of its (fresh) Skolem variables. For example, this rule may justify the conclusion \(k = t\) where \(k\) is the purification Skolem for \(t\), e.g. where the original form of \(k\) is \(t\).

Furthermore, notice that the rewriting and substitution is applied only within the side condition, meaning the rewritten form of the original form of \(F\) does not escape this rule.

enumerator CVC5_PROOF_RULE_MACRO_SR_PRED_ELIM

Builtin theory – Substitution + Rewriting predicate elimination

\[\inferrule{F, F_1 \dots F_n \mid (ids (ida (idr)?)?)?}{\texttt{rewrite}_{idr}(F \circ \sigma_{ids, ida}(F_n) \circ \cdots \circ \sigma_{ids, ida}(F_1))}\]

where \(ids\) and \(idr\) are method identifiers.

We rewrite only on the Skolem form of \(F\), similar to MACRO_SR_EQ_INTRO.

enumerator CVC5_PROOF_RULE_MACRO_SR_PRED_TRANSFORM

Builtin theory – Substitution + Rewriting predicate elimination

\[\inferrule{F, F_1 \dots F_n \mid G, (ids (ida (idr)?)?)?}{G}\]

where

\[\begin{split}\texttt{rewrite}_{idr}(F \circ \sigma_{ids, ida}(F_n) \circ\cdots \circ \sigma_{ids, ida}(F_1)) =\\ \texttt{rewrite}_{idr}(G \circ \sigma_{ids, ida}(F_n) \circ \cdots \circ \sigma_{ids, ida}(F_1))\end{split}\]

More generally, this rule also holds when: \(\texttt{Rewriter::rewrite}(\texttt{toOriginal}(F')) = \texttt{Rewriter::rewrite}(\texttt{toOriginal}(G'))\) where \(F'\) and \(G'\) are the result of each side of the equation above. Here, original forms are used in a similar manner to MACRO_SR_PRED_INTRO above.

enumerator CVC5_PROOF_RULE_ENCODE_EQ_INTRO

Builtin theory – Encode equality introduction

\[\inferrule{- \mid t}{t=t'}\]

where \(t\) and \(t'\) are equivalent up to their encoding in an external proof format.

More specifically, it is the case that \(\texttt{RewriteDbNodeConverter::postConvert}(t) = t;\). This conversion method for instance may drop user patterns from quantified formulas or change the representation of \(t\) in a way that is a no-op in external proof formats.

Note this rule can be treated as a REFL when appropriate in external proof formats.

enumerator CVC5_PROOF_RULE_DSL_REWRITE

Builtin theory – DSL rewrite

\[\inferrule{F_1 \dots F_n \mid id t_1 \dots t_n}{F}\]

where id is a ProofRewriteRule whose definition in the RARE DSL is \(\forall x_1 \dots x_n. (G_1 \wedge G_n) \Rightarrow G\) where for \(i=1, \dots n\), we have that \(F_i = \sigma(G_i)\) and \(F = \sigma(G)\) where \(\sigma\) is the substitution \(\{x_1\mapsto t_1,\dots,x_n\mapsto t_n\}\).

Notice that the application of the substitution takes into account the possible list semantics of variables \(x_1 \ldots x_n\). If \(x_i\) is a variable with list semantics, then \(t_i\) denotes a list of terms. The substitution implemented by \(\texttt{expr::narySubstitute}\) (for details, see expr/nary_term_util.h) which replaces each \(x_i\) with the list \(t_i\) in its place.

enumerator CVC5_PROOF_RULE_THEORY_REWRITE

Other theory rewrite rules

\[\inferrule{- \mid id, t = t'}{t = t'}\]

where id is the ProofRewriteRule of the theory rewrite rule which transforms \(t\) to \(t'\).

In contrast to DSL_REWRITE, theory rewrite rules used by this proof rule are not necessarily expressible in RARE. Each rule that can be used in this proof rule are documented explicitly in cases within the ProofRewriteRule enum.

enumerator CVC5_PROOF_RULE_ITE_EQ

Processing rules – If-then-else equivalence

\[\inferrule{- \mid \ite{C}{t_1}{t_2}}{\ite{C}{((\ite{C}{t_1}{t_2}) = t_1)}{((\ite{C}{t_1}{t_2}) = t_2)}}\]

enumerator CVC5_PROOF_RULE_TRUST

Trusted rule

\[\inferrule{F_1 \dots F_n \mid tid, F, ...}{F}\]

where \(tid\) is an identifier and \(F\) is a formula. This rule is used when a formal justification of an inference step cannot be provided. The formulas \(F_1 \dots F_n\) refer to a set of formulas that entail \(F\), which may or may not be provided.

enumerator CVC5_PROOF_RULE_TRUST_THEORY_REWRITE

Trusted rules – Theory rewrite

\[\inferrule{- \mid F, tid, rid}{F}\]

where \(F\) is an equality of the form \(t = t'\) where \(t'\) is obtained by applying the kind of rewriting given by the method identifier \(rid\), which is one of: RW_REWRITE_THEORY_PRE, RW_REWRITE_THEORY_POST, RW_REWRITE_EQ_EXT. Notice that the checker for this rule does not replay the rewrite to ensure correctness, since theory rewriter methods are not static. For example, the quantifiers rewriter involves constructing new bound variables that are not guaranteed to be consistent on each call.

enumerator CVC5_PROOF_RULE_SAT_REFUTATION

SAT Refutation for assumption-based unsat cores

\[\inferrule{F_1 \dots F_n \mid -}{\bot}\]

where \(F_1 \dots F_n\) correspond to the unsat core determined by the SAT solver.

enumerator CVC5_PROOF_RULE_DRAT_REFUTATION

DRAT Refutation

\[\inferrule{F_1 \dots F_n \mid D, P}{\bot}\]

where \(F_1 \dots F_n\) correspond to the clauses in the DIMACS file given by filename D and P is a filename of a file storing a DRAT proof.

enumerator CVC5_PROOF_RULE_SAT_EXTERNAL_PROVE

SAT external prove Refutation

\[\inferrule{F_1 \dots F_n \mid D}{\bot}\]

where \(F_1 \dots F_n\) correspond to the input clauses in the DIMACS file D.

enumerator CVC5_PROOF_RULE_RESOLUTION

Boolean – Resolution

\[\inferrule{C_1, C_2 \mid pol, L}{C}\]

where

• \(C_1\) and \(C_2\) are nodes viewed as clauses, i.e., either an OR node with each children viewed as a literal or a node viewed as a literal. Note that an OR node could also be a literal.

• \(pol\) is either true or false, representing the polarity of the pivot on the first clause

• \(L\) is the pivot of the resolution, which occurs as is (resp. under a NOT) in \(C_1\) and negatively (as is) in \(C_2\) if \(pol = \top\) (\(pol = \bot\)).

\(C\) is a clause resulting from collecting all the literals in \(C_1\), minus the first occurrence of the pivot or its negation, and \(C_2\), minus the first occurrence of the pivot or its negation, according to the policy above. If the resulting clause has a single literal, that literal itself is the result; if it has no literals, then the result is false; otherwise it’s an OR node of the resulting literals.

Note that it may be the case that the pivot does not occur in the clauses. In this case the rule is not unsound, but it does not correspond to resolution but rather to a weakening of the clause that did not have a literal eliminated.

enumerator CVC5_PROOF_RULE_CHAIN_RESOLUTION

Boolean – N-ary Resolution

\[\inferrule{C_1 \dots C_n \mid (pol_1 \dots pol_{n-1}), (L_1 \dots L_{n-1})}{C}\]

where

• let \(C_1 \dots C_n\) be nodes viewed as clauses, as defined above

• let \(C_1 \diamond_{L,pol} C_2\) represent the resolution of \(C_1\) with \(C_2\) with pivot \(L\) and polarity \(pol\), as defined above

• let \(C_1' = C_1\),

• for each \(i > 1\), let \(C_i' = C_{i-1} \diamond_{L_{i-1}, pol_{i-1}} C_i'\)

Note the list of polarities and pivots are provided as s-expressions.

The result of the chain resolution is \(C = C_n'\)

enumerator CVC5_PROOF_RULE_FACTORING

Boolean – Factoring

\[\inferrule{C_1 \mid -}{C_2}\]

where \(C_2\) is the clause \(C_1\), but every occurrence of a literal after its first occurrence is omitted.

enumerator CVC5_PROOF_RULE_REORDERING

Boolean – Reordering

\[\inferrule{C_1 \mid C_2}{C_2}\]

where the multiset representations of \(C_1\) and \(C_2\) are the same.

enumerator CVC5_PROOF_RULE_MACRO_RESOLUTION

Boolean – N-ary Resolution + Factoring + Reordering

\[\inferrule{C_1 \dots C_n \mid C, pol_1,L_1 \dots pol_{n-1},L_{n-1}}{C}\]

where

• let \(C_1 \dots C_n\) be nodes viewed as clauses, as defined in RESOLUTION

• let \(C_1 \diamond_{L,\mathit{pol}} C_2\) represent the resolution of \(C_1\) with \(C_2\) with pivot \(L\) and polarity \(pol\), as defined in RESOLUTION

• let \(C_1'\) be equal, in its set representation, to \(C_1\),

• for each \(i > 1\), let \(C_i'\) be equal, in its set representation, to \(C_{i-1} \diamond_{L_{i-1},\mathit{pol}_{i-1}} C_i'\)

The result of the chain resolution is \(C\), which is equal, in its set representation, to \(C_n'\)

enumerator CVC5_PROOF_RULE_MACRO_RESOLUTION_TRUST

Same as MACRO_RESOLUTION, but not checked by the internal proof checker.

\[\inferrule{F_1, (F_1 \rightarrow F_2) \mid -}{F_2}\]

The actual node for \(k\) is constructible via ProofRuleChecker::mkKindNode. If \(k\) is a binder kind (e.g. cvc5::Kind::FORALL) then \(f\) is a term of kind cvc5::Kind::VARIABLE_LIST denoting the variables bound by both sides of the conclusion. This rule is used for kinds that have a fixed arity, such as cvc5::Kind::ITE, cvc5::Kind::EQUAL, and so on. It is also used for cvc5::Kind::APPLY_UF where \(f\) must be provided. It is not used for equality between cvc5::Kind::HO_APPLY terms, which should use the HO_CONG proof rule.
