Question
Has anyone used the GLPK for production systems? I have an application currently powered by CPLEX and wish to replace it with a free software alternative.
It is used to solve a large MIP (thousands of variables) for a scheduling problem. I would like to know whether GLPK is mature enough to handle this.
Thanks
Solution
I've been using GLPK on 200,000+ variable problems - solves them in a few seconds, so yes if you can define your problem and don't mind C/C++ it's fine.
OTHER TIPS
I am not sure about GLPK as I do not have much experience with it. I am able to recommend https://projects.coin-or.org/Clp
It is open-source, written by IBM Research as part of their COmputational INfrastructure for Operations Research (COIN-OR) group.
Let me know how it works! Good luck, m
