Subject: | [Help-glpk] Increase PL speed |
Date: | Thu, 9 Nov 2006 18:37:23 +0300 |
Helloanyone. I have implemented a branch-and-bound by myself, using the GLPK lpx_simplex() routine to solve each linear problem I have. I want to know if anybody knows some #8220;best practices #8221; to increase the speed of my PLs? I am already using: lpx_set_int_parm(lp, LPX_K_PRESOL, 1); lpx_warm_up(lp); lpx_simplex(lp); Thanks a lot.
