z3是否找到所有可满足的模型

Question

存在一些约束，例如x + y＆gt; 5，x> 3，y＆lt; 4，所以模型组x = 4 y = 3，由z3给出。剂量z3可以递增给出模型，例如另一组模型x = 5，y = 2？ 谢谢。 问候

Answer 1

你能告诉我这件事会发生什么：

x,y = Bools('x y')

s = Solver()
s.add(Or(x,y))


count = 0
while s.check() == sat and count <= 50:
  print s.model()
  s.add(Or(x != s.model()[x], y != s.model()[y])) 
  count = count + 1
print count

输出是：

[y = False, x = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
[y = True]
