op-solver doesn't return

[aelzein1998]

Hello,

I am using the op-solver to run your evolutionary algorithm, ea4op. However, the algorithm doesn't return in many cases. I ensure that the cost matrix in the problem file is both symmetric and satisfies triangular inequality. I need the algorithm to let me know if there's no feasible solution. Instead, the program just runs forever...

Also, I am looking to produce paths, not cycles. Is there a way to do that?

Thank you.
