The different kinds of interpreted function kinds.
T1: p T2: (implies p q) [mp T1 T2]: qThe second antecedents may also be a proof for (iff p q).
T1: (R t s) [symmetry T1]: (R s t)
T1: (R t s) T2: (R s u) [trans T1 T2]: (R t u)
Z3_OP_PR_TRANSITIVITY_STAR: Condensed transitivity proof. It combines several symmetry and transitivity proofs. Example:
T1: (R a b) T2: (R c b) T3: (R c d) [trans* T1 T2 T3]: (R a d)
R must be a symmetric and transitive relation.
Assuming that this proof object is a proof for (R s t), then a proof checker must check if it is possible to prove (R s t) using the antecedents, symmetry and transitivity. That is, if there is a path from s to t, if we view every antecedent (R a b) as an edge between a and b.
T1: (R t_1 s_1) ... Tn: (R t_n s_n) [monotonicity T1 ... Tn]: (R (f t_1 ... t_n) (f s_1 ... s_n))Remark: if t_i == s_i, then the antecedent Ti is suppressed. That is, reflexivity proofs are suppressed to save space.
T1: (~ p q)
T1: f [proof-bind T1] forall (x) f
Z3_OP_PR_DISTRIBUTIVITY: Distributivity proof object. Given that f (= or) distributes over g (= and), produces a proof for
(= (f a (g c d)) (g (f a c) (f a d)))
If f and g are associative, this proof also justifies the following equality:
(= (f (g a b) (g c d)) (g (f a c) (f a d) (f b c) (f b d)))
where each f and g can have arbitrary number of arguments.
This proof object has no antecedents. Remark. This rule is used by the CNF conversion pass and instantiated by f = or, and g = and.
Z3_OP_PR_AND_ELIM: Given a proof for (and l_1 ... l_n), produces a proof for l_i
T1: (and l_1 ... l_n)
T1: (not (or l_1 ... l_n)) [not-or-elim T1]: (not l_i)
Z3_OP_PR_REWRITE: A proof for a local rewriting step (= t s). The head function symbol of t is interpreted.
This proof object has no antecedents. The conclusion of a rewrite rule is either an equality (= t s), an equivalence (iff t s), or equi-satisfiability (~ t s). Remark: if f is bool, then = is iff. Examples:
(= (+ x 0) x) (= (+ x 1 2) (+ 3 x)) (iff (or x false) x)
(iff (forall (x_1 ... x_m) (and p_1[x_1 ... x_m] ... p_n[x_1 ... x_m])) (and (forall (x_1 ... x_m) p_1[x_1 ... x_m]) ... (forall (x_1 ... x_m) p_n[x_1 ... x_m])))
Z3_OP_PR_ELIM_UNUSED_VARS: A proof for (iff (forall (x_1 ... x_n y_1 ... y_m) p[x_1 ... x_n]) (forall (x_1 ... x_n) p[x_1 ... x_n]))
It is used to justify the elimination of unused variables. This proof object has no antecedents.
Z3_OP_PR_DER: A proof for destructive equality resolution: (iff (forall (x) (or (not (= x t)) P[x])) P[t]) if x does not occur in t.
This proof object has no antecedents.
Several variables can be eliminated simultaneously.
T1: false [lemma T1]: (or (not l_1) ... (not l_n))This proof object has one antecedent: a hypothetical proof for false. It converts the proof in a proof for (or (not l_1) ... (not l_n)), when T1 contains the open hypotheses: l_1, ..., l_n. The hypotheses are closed after an application of a lemma. Furthermore, there are no other open hypotheses in the subtree covered by the lemma.
T1: (or l_1 ... l_n l_1' ... l_m') T2: (not l_1) ... T(n+1): (not l_n) [unit-resolution T1 ... T(n+1)]: (or l_1' ... l_m')
T1: p [iff-true T1]: (iff p true)
T1: (not p) [iff-false T1]: (iff p false)
[comm]: (= (f a b) (f b a)) f is a commutative operator. This proof object has no antecedents. Remark: if f is bool, then = is iff.
(or (not (and p q)) p) (or (not (and p q)) q) (or (not (and p q r)) p) (or (not (and p q r)) q) (or (not (and p q r)) r) ... (or (and p q) (not p) (not q)) (or (not (or p q)) p q) (or (or p q) (not p)) (or (or p q) (not q)) (or (not (iff p q)) (not p) q) (or (not (iff p q)) p (not q)) (or (iff p q) (not p) (not q)) (or (iff p q) p q) (or (not (ite a b c)) (not a) b) (or (not (ite a b c)) a c) (or (ite a b c) (not a) (not b)) (or (ite a b c) a (not c)) (or (not (not a)) (not a)) (or (not a) a)
Z3_OP_PR_DEF_INTRO: Introduces a name for a formula/term. Suppose e is an expression with free variables x, and def-intro introduces the name n(x). The possible cases are:
When e is of Boolean type:
or:
when e only occurs positively.
When e is of the form (ite cond th el):
Otherwise: [def-intro]: (= n e)
Z3_OP_PR_APPLY_DEF:
[apply-def T1]: F ~ n
F is 'equivalent' to n, given that T1 is a proof that n is a name for F.
Z3_OP_PR_IFF_OEQ:
T1: (iff p q) [iff~ T1]: (~ p q)
T1: (not s_1) ~ r_1 T2: (not s_2) ~ r_2 T3: s_1 ~ r_1' T4: s_2 ~ r_2' [nnf-pos T1 T2 T3 T4]: (~ (iff s_1 s_2) (and (or r_1 r_2') (or r_1' r_2)))The negation normal form steps NNF_POS and NNF_NEG are used in the following cases: (a) When creating the NNF of a positive force quantifier. The quantifier is retained (unless the bound variables are eliminated). Example
T1: q ~ q_new [nnf-pos T1]: (~ (forall (x T) q) (forall (x T) q_new))(b) When recursively creating NNF over Boolean formulas, where the top-level connective is changed during NNF conversion. The relevant Boolean connectives for NNF_POS are 'implies', 'iff', 'xor', 'ite'. NNF_NEG furthermore handles the case where negation is pushed over Boolean connectives 'and' and 'or'.
T1: (not s_1) ~ r_1 ... Tn: (not s_n) ~ r_n [nnf-neg T1 ... Tn]: (not (and s_1 ... s_n)) ~ (or r_1 ... r_n) and T1: (not s_1) ~ r_1 ... Tn: (not s_n) ~ r_n [nnf-neg T1 ... Tn]: (not (or s_1 ... s_n)) ~ (and r_1 ... r_n) and T1: (not s_1) ~ r_1 T2: (not s_2) ~ r_2 T3: s_1 ~ r_1' T4: s_2 ~ r_2' [nnf-neg T1 T2 T3 T4]: (~ (not (iff s_1 s_2)) (and (or r_1 r_2) (or r_1' r_2')))
[sk]: (~ (not (forall x (p x y))) (not (p (sk y) y))) [sk]: (~ (exists x (p x y)) (p (sk y) y))This proof object has no antecedents.
T1: p T2: (~ p q) [mp~ T1 T2]: q
- farkas - followed by rational coefficients. Multiply the coefficients to the inequalities in the lemma, add the (negated) inequalities and obtain a contradiction. - triangle-eq - Indicates a lemma related to the equivalence: (iff (= t1 t2) (and (<= t1 t2) (<= t2 t1))) - gcd-test - Indicates an integer linear arithmetic lemma that uses a gcd test.
Z3_OP_PR_HYPER_RESOLVE: Hyper-resolution rule.
The premises of the rules is a sequence of clauses. The first clause argument is the main clause of the rule. with a literal from the first (main) clause.
Premises of the rules are of the form
(or l0 l1 l2 .. ln)
or
(=> (and l1 l2 .. ln) l0)
or in the most general (ground) form:
(=> (and ln+1 ln+2 .. ln+m) (or l0 l1 .. ln))
In other words we use the following (Prolog style) convention for Horn implications: The head of a Horn implication is position 0, the first conjunct in the body of an implication is position 1 the second conjunct in the body of an implication is position 2
For general implications where the head is a disjunction, the first n positions correspond to the n disjuncts in the head. The next m positions correspond to the m conjuncts in the body.
The premises can be universally quantified so that the most general non-ground form is:
(forall (vars) (=> (and ln+1 ln+2 .. ln+m) (or l0 l1 .. ln)))
The hyper-resolution rule takes a sequence of parameters. The parameters are substitutions of bound variables separated by pairs of literal positions from the main clause and side clause.
n+1
arguments, where the first argument is the relation and the remaining n
elements correspond to the n
columns of the relation.Z3_OP_RA_NEGATION_FILTER: Intersect the first relation with respect to negation of the second relation (the function takes two arguments). Logically, the specification can be described by a function
target = filter_by_negation(pos, neg, columns)
where columns are pairs c1, d1, .., cN, dN of columns from pos and neg, such that target are elements in x in pos, such that there is no y in neg that agrees with x on the columns c1, d1, .., cN, dN.
n+1
arguments, where the first argument is a relation, and the remaining n
arguments correspond to a record.Z3_OP_FPA_BV2RM: Conversion of a 3-bit bit-vector term to a floating-point rounding-mode term
The conversion uses the following values: 0 = 000 = Z3_OP_FPA_RM_NEAREST_TIES_TO_EVEN, 1 = 001 = Z3_OP_FPA_RM_NEAREST_TIES_TO_AWAY, 2 = 010 = Z3_OP_FPA_RM_TOWARD_POSITIVE, 3 = 011 = Z3_OP_FPA_RM_TOWARD_NEGATIVE, 4 = 100 = Z3_OP_FPA_RM_TOWARD_ZERO.
