The message "OPTIMAL SOLUTION FOUND" means that the solver found an optimal solution to LP relaxation, not to MIP. > After time out when the output file is generated. It shows > "Status: INTEGER UNDEFINED" > What is the meaning of this ? This means that the solver did not find any integer feasible solution for 900 secs. > Should I consider that it is able to solve my prolbem ? Try to increase the time limit. _______________________________________________ Help-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-glpk
