Hi, I have a problem for integer variables with a lower bound equal at upper bound.
I obtain this error message: lpx_intopt: column 1 has incorrect bounds My problem is: PROBLEM: spConf_ whose formulation ref number is 1 Minimize Objectif: -11.6667 Yi0_copy -11.6667 Yi1_copy -5 Yi2_copy -5 Yi3_copy -2.7 Yi4_copy -4.6 Yi5_copy -4.6 Yi6_copy -4.6 Yi7_copy -21.5 Yi8_copy -21.5 Yi9_copy Subject To RTBH____: +7 Yi0_copy +7 Yi1_copy +2 Yi2_copy +2 Yi3_copy +2 Yi4_copy +4 Yi5_copy +4 Yi6_copy +4 Yi7_copy +9 Yi8_copy +9 Yi9_copy <= 10 Bounds 1 <= Yi0_copy <= 1 0 <= Yi1_copy <= 1 0 <= Yi2_copy <= 1 0 <= Yi3_copy <= 1 0 <= Yi4_copy <= 1 0 <= Yi5_copy <= 1 0 <= Yi6_copy <= 1 0 <= Yi7_copy <= 1 0 <= Yi8_copy <= 1 0 <= Yi9_copy <= 1 Integers Yi0_copy Yi1_copy Yi2_copy Yi3_copy Yi4_copy Yi5_copy Yi6_copy Yi7_copy Yi8_copy Yi9_copy End Why? Though, I use this function to include bound for the first variable: glp_set_col_bnds(glpkProbPtr,id+1,GLP_FX,dlb[id],dub[id]); Thanks Cédric -- View this message in context: http://www.nabble.com/Problem-in-the-MIP-problem-tp20029881p20029881.html Sent from the Gnu - GLPK - Bugs mailing list archive at Nabble.com. _______________________________________________ Bug-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/bug-glpk
