 SKOLEM_ADD_TO_POOL

A skolemizationaddtopool annotation.
An skolemizationaddtopool annotation indicates that when a quantified formula is skolemized, the skolemized 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 (SKOLEM_ADD_TO_POOL (ADD x 1) p)))
where assume that \(x\) has type Int. When this quantified formula is skolemized, e.g., with \(k\) of type Int, then the term
(ADD k 1)
is added to the pool \(p\) .

 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
(witness ((x S)) F)
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))

Create Op of this kind with:
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 \(z\) .
