   [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'.

• 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:

  - 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:

• 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.

  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.

• Z3_OP_INTERNAL: internal (often interpreted) symbol, but no additional information is exposed. Tools may use the string representation of the function declaration to obtain more information.
• Z3_OP_RECURSIVE: function declared as recursive
• Z3_OP_UNINTERPRETED: kind used for uninterpreted symbols.

Z3_string Z3_API Z3_benchmark_to_smtlib_string	(	Z3_context	c,
		Z3_string	name,
		Z3_string	logic,
		Z3_string	status,
		Z3_string	attributes,
		unsigned	num_assumptions,
		Z3_ast const	assumptions[],
		Z3_ast	formula
	)

Convert the given benchmark into SMT-LIB formatted string.

Warning

The result buffer is statically allocated by Z3. It will be automatically deallocated when Z3_del_context is invoked. So, the buffer is invalidated in the next call to Z3_benchmark_to_smtlib_string.

Parameters

c	- context.
name	- name of benchmark. The argument is optional.
logic	- the benchmark logic.
status	- the status string (sat, unsat, or unknown)
attributes	- other attributes, such as source, difficulty or category.
num_assumptions	- number of assumptions.
assumptions	- auxiliary assumptions.
formula	- formula to be checked for consistency in conjunction with assumptions.

Z3_datatype_update_field()

Z3_ast Z3_API Z3_datatype_update_field	(	Z3_context	c,
		Z3_func_decl	field_access,
		Z3_ast	t,
		Z3_ast	value
	)

Update record field with a value.

This corresponds to the 'with' construct in OCaml. It has the effect of updating a record field with a given value. The remaining fields are left unchanged. It is the record equivalent of an array store (see

See also

Z3_mk_store). If the datatype has more than one constructor, then the update function behaves as identity if there is a mismatch between the accessor and constructor. For example ((_ update-field car) nil 1) is nil, while ((_ update-field car) (cons 2 nil) 1) is (cons 1 nil).

Precondition

Z3_get_sort_kind(Z3_get_sort(c, t)) == Z3_get_domain(c, field_access, 1) == Z3_DATATYPE_SORT

Z3_get_sort(c, value) == Z3_get_range(c, field_access)

Add property about the predicate pred. Add a property of predicate pred at level. It gets pushed forward when possible.

Note: level = -1 is treated as the fixedpoint. So passing -1 for the level means that the property is true of the fixed-point unfolding with respect to pred.

Parameters

c	- context

The number of arguments num_args should be equal to the number of sorts in the domain of r. Each sort in the domain should be an integral (bit-vector, Boolean or or finite domain sort).
