If I recall correctly SCIP has some techniques from constraint programming that are very effective for some classes of problems, but it does depend on problem structure, and probably how the problem is modelled. So at a guess, some modifications would be required to take advantage of the speedups. The only reliable way to find out if benchmarks are relevant to try (small instances of) your problems on the solver in question. Perhaps someone with more personal experience SCIP can tell you more. d _______________________________________________ Help-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-glpk
