Hi G.S, It is neccesary to set parm.presolve=ON before solving MIP. In fact, I've tried with parm.presolve=OFF but the results are always 0. Anyway, thank you.
Something else is wrong. Presolve might be useful for performance, but it should never be necessary. If your experiments included the heuristic solution, perhaps the solution was not feasible. -- Michael [email protected] "On Monday, I'm gonna have to tell my kindergarten class, whom I teach not to run with scissors, that my fiance ran me through with a broadsword." -- Lily _______________________________________________ Help-glpk mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-glpk
