Question

我正在尝试使用C ++ / C API for z3（v4.5.1）加载smt2文件，然后使用API添加断言，其中包含在smt2文件中声明的数据类型和函数。

以下是我将文件加载到求解器的示例：

;(declare-sort Person)
(declare-datatypes () ((Person (person (name String)))))
(declare-fun related (Person Person) Bool)
(declare-fun father (Person Person) Bool)
(declare-fun sibling (Person Person) Bool)

; related symetric
(assert
  (forall ((p Person) (q Person))
    (=> (related p q)
        (related q p))))
; related transitive
(assert
  (forall ((p Person) (q Person) (j Person))
    (=> (and (related p q) (related q j))
        (related p j))))
; the father of a person is related to that person
(assert
  (forall ((p Person) (q Person))
    (=> (father p q)
        (related p q))))
; for all people, there exists another person that is their father
(assert
  (forall ((p Person))
    (exists ((q Person)) (father q p))))
; sibling symetric
(assert
  (forall ((p Person) (q Person))
    (=> (sibling p q) (sibling q p))))
; siblings have the same father
(assert
  (forall ((p Person) (q Person) (j Person))
    (=> (and (sibling p q) (father j p))
        (father j q))))

(declare-fun get-father (Person) Person)
; here we use a double implication to define the behavior of get-father
(assert
  (forall ((p Person) (q Person))
    (= (father q p) (= (get-father p) q))))

那么如何使用C或C ++ API来使用smt2文件中定义的内容？（如果可能的话）。我想使用smt2文件中定义的函数和数据类型进行更多断言，获取模型，然后进行评估。如果有人感兴趣，以下是smt2文件的内容：

这是一个非常＆＃34; z3实现特定＆＃34;题。如果您向开发人员提交了一张票证，您可能会得到更好的回复：https://github.com/Z3Prover/z3/issues

使用C ++ API加载smt2文件后，将断言添加到Z3
