Hello, I am afraid it is ambiguous which constraints are causing the trouble.
You could probably try the following. Introduce two new continuous variables xp >= 0 and xn >= 0 to each constraint. For example: x1 + 2 x2 = 3 after introducing the variables x1 + 2 x2 + (xp - xn) = 3 and change the objective function: minimize: sum xp + sum xn This problem must have a solution. For those constraints which are violated the corresponding xp or xn will not equal zero. Unfortunately it may turn out that all constraints are violated... If you are lucky there will be only a few constraints with non-zero xp and xn variables. Good luck, Ali _______________________________________________ Help-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-glpk
