Hi, Your question is a little off-topic.
Ipopt is very robust / stable but slow. The other open-source nonlinear solvers i tried so far failed to solve my problems. https://projects.coin-or.org/Ipopt The commercial solver CONOPT is said to be both fast and robust / stable. http://www.conopt.com/ Good luck, Ali _______________________________________________ Help-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-glpk
