To find a first integer feasible solution it is better to use --bestp rather than --bestb (the latter is default option). The best projection heuristic (--bestp) selects a subproblem whose solution to lp relaxation is close to an integral point while the best bound heuristic (--bestb) attempts to minimize the size of the search tree. _______________________________________________ Help-glpk mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-glpk
