 INST_ADD_TO_POOL

A instantantiationaddtopool annotation.
An instantantiationaddtopool annotation indicates that when a quantified formula is instantiated, the instantiated version of a term should be added to the given pool.
For example, consider a quantified formula:
(FORALL (VARIABLE_LIST x) F (INST_PATTERN_LIST (INST_ADD_TO_POOL (ADD x 1) p)))
where assume that \(x\) has type Int. When this quantified formula is instantiated with, e.g., the term \(t\) , the term
(ADD t 1)
is added to pool \(p\) .

 INST_POOL

Instantiation pool annotation.
Specifies an annotation for pool based instantiation.
 In detail, pool symbols can be declared via the method
A pool symbol represents a set of terms of a given sort. An instantiation pool annotation should either: (1) have child sets matching the types of the quantified formula, (2) have a child set of tuple type whose component types match the types of the quantified formula.
For an example of (1), for a quantified formula:
(FORALL (VARIABLE_LIST x y) F (INST_PATTERN_LIST (INST_POOL p q)))
if \(x\) and \(y\) have Sorts \(S_1\) and \(S_2\) , then pool symbols \(p\) and \(q\) should have Sorts (Set \(S_1\) ) and (Set \(S_2\) ), respectively. This annotation specifies that the quantified formula above should be instantiated with the product of all terms that occur in the sets \(p\) and \(q\) .
Alternatively, as an example of (2), for a quantified formula:
(FORALL (VARIABLE_LIST x y) F (INST_PATTERN_LIST (INST_POOL s)))
\(s\) should have Sort (Set (Tuple \(S_1\) \(S_2\) )). This annotation specifies that the quantified formula above should be instantiated with the pairs of values in \(s\) .

 WITNESS

Witness.
The syntax of a witness term is similar to a quantified formula except that only one variable is allowed. For example, the term

returns an element \(x\) of Sort \(S\) and asserts formula \(F\) .
The witness operator behaves like the description operator (see https: no \(x\) that satisfies \(F\) . But if such \(x\) exists, the witness operator does not enforce the following axiom which ensures uniqueness up to logical equivalence:
\[\forall x. F \equiv G \Rightarrow witness~x. F = witness~x. G\]For example, if there are two elements of Sort \(S\) that satisfy formula \(F\) , then the following formula is satisfiable:
(distinct (witness ((x Int)) F) (witness ((x Int)) F))

Note
This kind is primarily used internally, but may be returned in models (e.g., for arithmetic terms in nonlinear queries). However, it is not supported by the parser. Moreover, the user of the API should be cautious when using this operator. In general, all witness terms
(witness ((x Int)) F)
should be such that(exists ((x Int)) F)
is a valid formula. If this is not the case, then the semantics in formulas that use witness terms may be unintuitive. For example, the following formula is unsatisfiable:(or (= (witness ((x Int)) false) 0) (not (= (witness ((x Int)) false) 0))
, whereas notice that(or (= z 0) (not (= z 0)))
is true for any \(z\) .
