Dear all, I have a big size problem to be solved in GLPK (around 400000 rows and 1 million columns). The last simulation I run to solve this problem, I got a segmentation fault because of the size of the problem. I was wondering if it is possible to give to GLPK an initial solution to the problem I am trying to solve so that the number of iterations the solver has to do afterwards is decreased, and be able to get a solution. Is this possible? how would be the way to do it? I didn't see this explained online or in the user's manual. Moreover, do you think decreasing the tolerance would help in this case? Many thanks, Juan _______________________________________________ Help-glpk mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-glpk
