如何使用Alt-Ergo执行以下SMT-LIB代码

问题描述

以下SMT-LIB代码在Z3，MathSat和CVC4中运行都没有问题，但在Alt-Ergo中却没有运行，请让我知道会发生什么，非常感谢:

The following SMT-LIB code runs without problems in Z3, MathSat and CVC4 but it is not running in Alt-Ergo, please let me know what happens, many thanks:

(set-logic QF_UF)
(set-option :incremental true)
(set-option :produce-models true)
(declare-fun m () Bool)
(declare-fun p () Bool)
(declare-fun b () Bool)
(declare-fun c () Bool)
(declare-fun r () Bool)
(declare-fun al () Bool)
(declare-fun all () Bool)
(declare-fun la () Bool)
(declare-fun lal () Bool)
(declare-fun g () Bool)
(declare-fun a () Bool)
(define-fun conjecture () Bool
(and (= (and (not r) c) m) (= p m) (= b m) (= c (not g)) 
     (= (and (not al) (not all)) r) (= (and la b) al) 
     (= (or al la lal) all) (= (and (not g) p a) la) 
     (= (and (not g) (or la a)) lal)))
(push 1)
(assert (and conjecture (= a false) (= g false)))
(check-sat)
(get-model)
(pop 1)
(push 1)
(assert (and conjecture (= a false) (= g true)))
(check-sat)
(get-model)
(pop 1)
(push 1)
(assert (and conjecture (= a true) (= g true)))
(check-sat)
(get-model)
(pop 1)
(push 1)
(assert (and conjecture (= a true) (= g false)))
(check-sat)
(get-model)

推荐答案

目前，Alt-Ergo尚未完全支持SMT-2格式.特别是，无法识别命令get-model.

For now, Alt-Ergo does not provide a full support for the SMT-2 format. In particular, the command get-model is not recognized.

此外，将忽略命令push和pop.这就是为什么Alt-Ergo在给定代码上说坐着，坐着，...坐着(删除get-model时).

Moreover, the commands push and pop are ignored. This is why Alt-Ergo says sat, unsat, ..., unsat on the given code (when get-model is removed).
