Hello,
I've using GLPK to model and solve a linear problem for quite a while. According to this mailing list, I'm lucky to have it solved using GLPK. The only reason why it's so quick to solve it if the Fpump.
Recently, I've change the way I model the problem to satisfy a new business need and it's just taking for ever. Looking at the log, I see "FPUMP heuristic cannot be applied due to general integer variables". Correct me if I'm wrong, fpump can't be enabled because I've introduce an integer variable ?
