Z3 如何使用存在量词编写长smt lib表达式?

Z3 如何使用存在量词编写长smt lib表达式?,z3,smt,Z3,Smt,我有下面的表达 (declare-fun x00 () Real) (declare-fun x01 () Real) (declare-fun x10 () Real) (declare-fun x11 () Real) (declare-fun t0init () Real) (declare-fun z0init0 () Real) (declare-fun z0init1 () Real) (assert (>= t0init 0)) (assert (= (+ x00 z0ini

我有下面的表达

(declare-fun x00 () Real)
(declare-fun x01 () Real)
(declare-fun x10 () Real)
(declare-fun x11 () Real)
(declare-fun t0init () Real)
(declare-fun z0init0 () Real)
(declare-fun z0init1 () Real)
(assert (>= t0init 0))
(assert (= (+ x00 z0init0) x10))
(assert (= (+ x01 z0init1) x11))
(assert (< (+ (* 1 x00)(* 0 x01)) 0.0))
(assert (= (+ (* 0 x00)(* 1 x01)) 0.0))
(assert (< (+ (* 1 x10)(* 0 x11)) 0.0))
(assert (= (+ (* 0 x10)(* 1 x11)) 0.0))
...
(assert (< (+ (* 1 x40)(* 0 x41)) 0.0))
(assert (= (+ (* 0 x40)(* 1 x41)) 0.0))
(assert (= (+ (* 1 z4end0)(* 0 z4end1)) (* t4end 1)))
(assert (= (+ (* 0 z4end0)(* 1 z4end1)) (* t4end -2)))
然后执行量词消除

有人知道如何进行吗? 我知道如何使用z3py,但我需要一些更快的解决方案


非常感谢您的提示。

一个可能的解决方案如下

(declare-fun x00 () Real)
(declare-fun x01 () Real)
(declare-fun x10 () Real)
(declare-fun x11 () Real)
(declare-fun t0init () Real)
(declare-fun z0init0 () Real)
(declare-fun z0init1 () Real)
(define-fun conjecture () Bool
   (and (>= t0init 0) (= (+ x00 z0init0) x10) (= (+ x01 z0init1) x11)))
(assert (exists ((x00 Real) (x01 Real)) conjecture))
(check-sat)
相应的输出是

我不确定你需要的量词消去法是否适用于Z3。也许对于你的问题,“Redlog”的“Reduce”是更好的选择。祝你一切顺利
