Hi, I use " glp_ios_branch_upon(glp_tree *tree, int j, int sel) " to select a next variable to branch on. Here I set int sel = GLP_NO_BRNCH which says that it uses general selection technique. Can you please tell when it uses general selection technique, does it use a heuristic suggested by Tomlin to select next branch based on pseudo-costs or anything else? Also, if for any other method of variable selection which I implement, how can I use same technique to select next branch? Do I need to copy the subroutine branch_drtom to my code and then say int sel = GLP_NO_BRNCH wherever it says select up or down branch to branch on? -- Thanks with Best Regards, Sheetal _______________________________________________ Help-glpk mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-glpk
