Oh, sorry. And thank you for forwading and answering it. I wondered if I had to subscribe before posting, then read several messages which said "if you have a question, write to [email protected]" without mentionning the need to create an account first, so... ^^; > The gap of the last solution can be gathered using a callback function. > > You can find an example at > http://sourceforge.net/p/glpk-java/code/HEAD/tree/trunk/examples/java/GmplSwing.java Thanks ! It seems to be done at line 722. It does not seem to be very practical for what I want to do, however: given that the gap will be known only *inside* of the callback function, is there a "natural" way to write the gap "outside" of the function's scope so that it can be read right after the call to glp_intopt? Or are we forced to define a global variable somewhere? In your case it seems to be the 'progressTree' variable, but I don't have classes in C ^^; Maybe that could become a problem for us if several GLPK instances run in parallel :-/ Furthermore, would you happen to know how to "detect" that the exploration is finished, so that we only compute this gap when necessary, i.e. right before glp_intopt returns? Thank you very much for what you already answered, Nathann _______________________________________________ Help-glpk mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-glpk
