There is a constraints like x >=0 && x < 3 && x > a[x],where a[3] = {1,2,3} I want to know how klee to judge its validity,when a[3] = {4,5,6},its validity is -1 and when a[3] = {1,2,3},how to solve a test case. Thanks very much Yours' qingyang -------------- next part -------------- HTML attachment scrubbed and removed
