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 supressed 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

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.

Compute an interpolant from a refutation. This takes a proof of "false" from a set of formulas C, and an interpolation pattern. The pattern pat is a formula combining the formulas in C using logical conjunction and the "interp" operator (see Z3_mk_interpolant). This interp operator is logically the identity operator. It marks the sub-formulas of the pattern for which interpolants should be computed. The interpolant is a map sigma from marked subformulas to formulas, such that, for each marked subformula phi of pat (where phi sigma is phi with sigma(psi) substituted for each subformula psi of phi such that psi in dom(sigma)):
1) phi sigma implies sigma(phi), and
2) sigma(phi) is in the common uninterpreted vocabulary between the formulas of C occurring in phi and those not occurring in phi
and moreover pat sigma implies false. In the simplest case an interpolant for the pattern "(and (interp A) B)" maps A to an interpolant for A /\ B.
The return value is a vector of formulas representing sigma. The vector contains sigma(phi) for each marked subformula of pat, in pre-order traversal. This means that subformulas of phi occur before phi in the vector. Also, subformulas that occur multiply in pat will occur multiply in the result vector.
In particular, calling Z3_get_interpolant on a pattern of the form (interp ... (interp (and (interp A_1) A_2)) ... A_N) will result in a sequence interpolant for A_1, A_2,... A_N.
Neglecting interp markers, the pattern must be a conjunction of formulas in C, the set of premises of the proof. Otherwise an error is flagged.
Any premises of the proof not present in the pattern are treated as "background theory". Predicate and function symbols occurring in the background theory are treated as interpreted and thus always allowed in the interpolant.
Interpolant may not necessarily be computable from all proofs. To be sure an interpolant can be computed, the proof must be generated by an SMT solver for which interpoaltion is supported, and the premises must be expressed using only theories and operators for which interpolation is supported.
Currently, the only SMT solver that is supported is the legacy SMT solver. Such a solver is available as the default solver in Z3_context
objects produced by Z3_mk_interpolation_context. Currently, the theories supported are equality with uninterpreted functions, linear integer arithmetic, and the theory of arrays (in SMT-LIB terms, this is AUFLIA). Quantifiers are allowed. Use of any other operators (including "labels") may result in failure to compute an interpolant from a proof.

Referenced by z3::reset_params(), and z3py::reset_params().
Set a global (or module) parameter. This setting is shared by all Z3 contexts.
When a Z3 module is initialized it will use the value of these parameters when Z3_params objects are not provided.
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 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_push and #Z3_pop. In other words, a Z3_ast object remains valid until there is a call to Z3_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.
Further remarks:
Z3_context Z3_API Z3_mk_context_rc | ( | Z3_config | c | ) |
Create a context using the given configuration. This function is similar to Z3_mk_context. However, in the context returned by this function, the user is responsible for managing Z3_ast 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.

Parse the given string using the SMT-LIB parser.
The symbol table of the parser can be initialized using the given sorts and declarations. The symbols in the arrays sort_names
and decl_names
don't need to match the names of the sorts and declarations in the arrays sorts
and decls
. This is an useful feature since we can use arbitrary names to reference sorts and declarations defined using the C API.
The formulas, assumptions and declarations defined in str
can be extracted using the functions: Z3_get_smtlib_num_formulas, Z3_get_smtlib_formula, Z3_get_smtlib_num_assumptions, Z3_get_smtlib_assumption, Z3_get_smtlib_num_decls, and Z3_get_smtlib_decl.

File formats: Currently two formats are supported, based on SMT-LIB2. For sequence interpolants, the sequence of constraints is represented by the sequence of "assert" commands in the file.
For tree interpolants, one symbol of type bool is associated to each vertex of the tree. For each vertex v there is an "assert" of the form:
(implies (and c1 ... cn f) v)
where c1 .. cn are the children of v (which must precede v in the file) and f is the formula assiciated to node v. The last formula in the file is the root vertex, and is represented by the predicate "false".
A solution to a tree interpolation problem can be thought of as a valuation of the vertices that makes all the implications true where each value is represented using the common symbols between the formulas in the subtree and the remainder of the formulas.

) |
Convert an AST into a FUNC_DECL_AST. This is just type casting.
void Z3_API Z3_toggle_warning_messages | ( | Z3_bool | enabled | ) |
Enable/disable printing warning messages to the console.
Warnings are printed after passing true
, warning messages are suppressed after calling this method with false
.
Z3_ast Z3_API Z3_translate | ( | Z3_context | source, |
Z3_ast | a, | ||
Z3_context | target | ||
) |
Translate/Copy the AST a
from context source
to context target
. AST a
must have been created using context source
.
Referenced by AstRef::translate().
Z3_ast Z3_API Z3_update_term | ( | Z3_context | c, |
Z3_ast | a, | ||
unsigned | num_args, | ||
Z3_ast const | args[] | ||
) |
Update the arguments of term a
using the arguments args
. The number of arguments num_args
should coincide with the number of arguments to a
. If a
is a quantifier, then num_args has to be 1.

Write an interpolation problem to file suitable for reading with Z3_read_interpolation_problem. The output file is a sequence of SMT-LIB2 format commands, suitable for reading with command-line Z3 or other interpolating solvers.
ctx | The Z3 context. Must be generated by z3_mk_interpolation_context |
num | The number of constraints in the sequence |
cnsts | Array of constraints |
parents | The parents vector (or NULL for sequence) |
filename | The file name to write |
num_theory | Number of theory terms |
theory | Theory terms |
