Hi all, I'm using glpk 4.8 (via Java JNI http://bjoern.dapnet.de/glpk/index.htm) as a feasibility solver. One of my constraint is that the sum of structural variables = 1.
When some coefficients are very small, e.g. 1E-6, then the constraint that the sum of structural variables = 1 is not enforced. I got all of them with 0. If I ignore those small coefficients (<= 1E-6), the constraint that the sum of structural variables = 1 is satisfied. But I'm not sure if this will affect the accuracy of my program. Does anyone know if glpk has some precision lower bound or this is a bug? Thank you very much Yao _______________________________________________ Help-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-glpk
