Hello, I'm using GLPK to solve vertex coloring problem in graphs. I managed to get it working using the custom branching technique. However, when I implemented providing heuristic solutions in response of GLP_IHEUR, the function glp_ios_heur_sol does not complain but after some time, during the branch-and-cut process, the program crashes with the following message: Assertion failed: 1 <= k && k <= m+n Error detected in file glpapi12.c at line 1081 That happens soon after the heuristic solution is acknowledged. Is a bug causing this? I can provide more info if necessary.
