Juan said he received a "segmentation fault" that is mostly likely due to the use of memory in the basis factorization. Providing an initial basis will cut down the number of iterations, but I would think it would be highly unlikely to cut down the memory requirements.
Juan - are you using the 64-bit or the 32-bit compilation? If you're using the 32-bit, then maybe switching to the 64-bit might help if you have lots of memory on your machine. Otherwise, you may have to consider reformulation of your model or another technique such as column generation. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Heinrich Schuchardt Sent: Tuesday, September 17, 2013 9:56 AM To: Juan J. Rojas; Help Glpk Subject: Re: [Help-glpk] [Fwd: Providing initial solution] Hello Juan, please, read chapter "LP basis constructing routines" of the doc/glpk.pdf of the GLPK source distribution. After constructing a valid basis call glp_warm_up() and then glp_simplex() with presolver disabled. Best regards Heinrich Schuchardt http://www.xypron.de > Gesendet: Dienstag, 17.
