Dear Lutz, This works for me now. Thank you very much for your help. Regards, Can Hi, When you use Grid, the Solver log is suppressed by default, since it would be all mixed if you have many solves in parallel. However, you can instruct GAMS to write the log to a file, which would also cause the sol...

How to enable solver output when using Grid GAMS

Hi folks, I'm using Grid GAMS to solve a problem using Benders decomposition. Here's the code I write for solving some subproblems in parallel. ------------------------------------------------- loop(w3, freeze(w2) = no; freeze(w3) = yes; solve BenderSub using MINLP minimizing COST; Bendersub_handle(...
