enum Z3_decl_kind |
The different kinds of interpreted function kinds.
Z3_OP_PR_MODUS_PONENS: Given a proof for p and a proof for (implies p q), produces a proof for q.
T1: p T2: (implies p q)
The 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)
Example: <div class="fragment"><pre class="fragment"> T1: (R a b) T2: (R c b) T3: (R c d) [trans* T1 T2 T3]: (R a d) </pre></div> 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.
Z3_OP_PR_MONOTONICITY: Monotonicity proof object.
T1: (R t_1 s_1) ... Tn: (R t_n s_n)
Remark: if t_i == s_i, then the antecedent Ti is suppressed. That is, reflexivity proofs are suppressed to save space.
Z3_OP_PR_QUANT_INTRO: Given a proof for (~ p q), produces a proof for (~ (forall (x) p) (forall (x) q)).
T1: (~ p q)
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)
Z3_OP_PR_NOT_OR_ELIM: Given a proof for (not (or l_1 ... l_n)), produces a proof for (not l_i).
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: <div class="fragment"><pre class="fragment"> (= (+ x 0) x) (= (+ x 1 2) (+ 3 x)) (iff (or x false) x) </pre></div>
Z3_OP_PR_PUSH_QUANT: A proof for:
(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])))
This proof object has no antecedents.
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.
Z3_OP_PR_LEMMA:
T1: false
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.
<div class="fragment"><pre class="fragment"> (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) </pre></div> This proof object has no antecedents. Note: all axioms are propositional tautologies. Note also that 'and' and 'or' can take multiple arguments. You can recover the propositional tautologies by unfolding the Boolean connectives in the axioms a small bounded number of steps (=3).
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_NNF_POS: Proof for a (positive) NNF step. Example:
T1: (not s_1) ~ r_1 T2: (not s_2) ~ r_2 T3: s_1 ~ r_1' T4: s_2 ~ r_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
(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'.
Z3_OP_PR_NNF_NEG: Proof for a (negative) NNF step. Examples:
T1: (not s_1) ~ r_1 ... Tn: (not s_n) ~ r_n
and T1: (not s_1) ~ r_1 ... Tn: (not s_n) ~ 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'
(and (or r_1 r_2) (or r_1' r_2')))
<div class="fragment"><pre class="fragment"> [sk]: (~ (not (forall x (p x y))) (not (p (sk y) y))) [sk]: (~ (exists x (p x y)) (p (sk y) y)) </pre></div> This proof object has no antecedents.
Z3_OP_PR_MODUS_PONENS_OEQ: Modus ponens style rule for equi-satisfiability.
T1: p T2: (~ p q)
Z3_OP_PR_TH_LEMMA: Generic proof for theory lemmas.
The theory lemma function comes with one or more parameters. The first parameter indicates the name of the theory. For the theory of arithmetic, additional parameters provide hints for checking the theory lemma. The hints for arithmetic are:
(iff (= t1 t2) (and (<= t1 t2) (<= t2 t1)))
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.

Retrieve congruence class representatives for terms.
The function can be used for relying on Z3 to identify equal terms under the current set of assumptions. The array of terms and array of class identifiers should have the same length. The class identifiers are numerals that are assigned to the same value for their corresponding terms if the current context forces the terms to be equal. You cannot deduce that terms corresponding to different numerals must be all different, (especially when using non-convex theories). All implied equalities are returned by this call. This means that two terms map to the same class identifier if and only if the current context implies that they are equal.
A side-effect of the function is a satisfiability check on the assertions on the solver that is passed in. The function return Z3_L_FALSE
if the current assertions are not satisfiable.

Referenced by z3::reset_params().
Set a global (or module) parameter. This setting is shared by all Z3 contexts.

The name of parameter can be composed of characters [a-z][A-Z], digits [0-9], '-' and '_'. The character '.' is a delimiter (more later).
The parameter names are case-insensitive. The character '-' should be viewed as an "alias" for '_'. Thus, the following parameter names are considered equivalent: "pp.decimal-precision" and "PP.DECIMAL_PRECISION".
This function can be used to set parameters for a specific Z3 module. This can be done by using <module-name>.<parameter-name>. For example: Z3_global_param_set('pp.decimal', 'true') will set the parameter "decimal" in the module "pp" to true.

Create a bound variable.
Bound variables are indexed by de-Bruijn indices. It is perhaps easiest to explain the meaning of de-Bruijn indices by indicating the compilation process from non-de-Bruijn formulas to de-Bruijn format.
abs(forall (x1) phi) = forall (x1) abs1(phi, x1, 0) abs(forall (x1, x2) phi) = abs(forall (x1) abs(forall (x2) phi)) abs1(x, x, n) = b_n abs1(y, x, n) = y abs1(f(t1,...,tn), x, n) = f(abs1(t1,x,n), ..., abs1(tn,x,n)) abs1(forall (x1) phi, x, n) = forall (x1) (abs1(phi, x, n+1))
The last line is significant: the index of a bound variable is different depending on the scope in which it appears. The deeper x appears, the higher is its index.

Create a context using the given configuration.
After a context is created, the configuration cannot be changed, although some parameters can be changed using Z3_update_param_value. All main interaction with Z3 happens in the context of a Z3_context
.
In contrast to Z3_mk_context_rc, the life time of Z3_ast
objects are determined by the scope level of Z3_solver_push and Z3_solver_pop. In other words, a Z3_ast
object remains valid until there is a call to Z3_solver_pop that takes the current scope below the level where the object was created.
Note that all other reference counted objects, including Z3_model
, Z3_solver
, Z3_func_interp
have to be managed by the caller. Their reference counts are not handled by the context.

Z3_sort
, Z3_func_decl

reference counters. Managing reference counters is a burden and error-prone, but allows the user to use the memory more efficiently. The user must invoke Z3_inc_ref for any Z3_ast
returned by Z3, and Z3_dec_ref whenever the Z3_ast
is not needed anymore. This idiom is similar to the one used in BDD (binary decision diagrams) packages such as CUDD.

Note that these differences can result in very different performance compared to Z3_mk_solver().

Referenced by solver::solver().
Z3_solver Z3_API Z3_mk_solver | ( | Z3_context | c | ) |
Create a new solver. This solver is a "combined solver" (see combined_solver module) that internally uses a non-incremental (solver1) and an incremental solver (solver2). This combined solver changes its behaviour based on how it is used and how its parameters are set.
If the solver is used in a non incremental way (i.e. no calls to Z3_solver_push() or Z3_solver_pop(), and no calls to Z3_solver_assert() or Z3_solver_assert_and_track() after checking satisfiability without an intervening Z3_solver_reset()) then solver1 will be used. This solver will apply Z3's "default" tactic.
The "default" tactic will attempt to probe the logic used by the assertions and will apply a specialized tactic if one is supported. Otherwise the general (and-then simplify smt)
tactic will be used.
If the solver is used in an incremental way then the combined solver will switch to using solver2 (which behaves similarly to the general "smt" tactic).
Note however it is possible to set the solver2_timeout
, solver2_unknown
, and ignore_solver1
parameters of the combined solver to change its behaviour.
The function Z3_solver_get_model retrieves a model if the assertions is satisfiable (i.e., the result is Z3_L_TRUE

.
This API is an alternative to Z3_solver_check_assumptions for extracting unsat cores. Both APIs can be used in the same solver. The unsat core will contain a combination of the Boolean variables provided using Z3_solver_assert_and_track and the Boolean literals provided using Z3_solver_check_assumptions.

) |
Check whether the assertions in a given solver are consistent or not.
The function Z3_solver_get_model retrieves a model if the assertions is satisfiable (i.e., the result is Z3_L_TRUE
) and model construction is enabled. Note that if the call returns Z3_L_UNDEF
, Z3 does not ensure that calls to Z3_solver_get_model succeed and any models produced in this case are not guaranteed to satisfy the assertions.
The function Z3_solver_get_proof retrieves a proof if proof generation was enabled when the context was created, and the assertions are unsatisfiable (i.e., the result is Z3_L_FALSE
).

extract a next cube for a solver. The last cube is the constant true
or false
. The number of (non-constant) cubes is by default 1. For the sat solver cubing is controlled using parameters sat.lookahead.cube.cutoff and sat.lookahead.cube.fraction.
The third argument is a vector of variables that may be used for cubing. The contents of the vector is only used in the first call. The initial list of variables is used in subsequent calls until it returns the unsatisfiable cube. The vector is modified to contain a set of Autarky variables that occur in clauses that are affected by the (last literal in the) cube. These variables could be used by a different cuber (on a different solver object) for further recursive cubing.
The last argument is a backtracking level. It instructs the cube process to backtrack below the indicated level for the next cube.
