Simplex solver Library Help

Question

I have to migrate some old code which used the c based LPPSolver library to solve a Simplex problem. My problem in Java is to find anon commercial JAVA based solver which can handle large number of variables. I have tried the Apache SimplexSolver. But in most of my cases I get not feasible solution. Please help. Thanks

Yes I have read these posts. But they never really really gave a solution. One of them proposed the Apache SimplexSolver which I tried out but I am not getting reliable solutions... — foolingcoder, Oct 06 '10 at 09:44

Thanks. But basically I want a performent Java based Solver. LPSOLVE has a JAVA interface but the core solver is in C – foolingcoder Oct 12 '10 at 07:31
I have serious doubts about finding a good Java-based solver. – Pablo Rodriguez Oct 26 '11 at 12:38

¿Have you looked at eh COIN-OR projects? Maybe there is a Java-based solver.

But the matter seems to be that your problem has no solution with your parameters and data. You can try to solve it on any of the solvers of the NEOS Server to see where the problem could be.
