Hello Andrew, the problem below can be solved by the dual simplex glpsol.exe -m test.mod --dual
Yet glp_get_dual_stat() returns GLP_INFEAS dual solution is infeasible for the problem when called in glplpx03.c. The dual values for the constraints are c1: 1.000000 c2: 1.000000 c3: -0.000000e+000 Best regards Xypron UdayV wrote: > > Hello, > > I am not sure if this is a bug or not, but I am not able to get > sensitivity bounds for the following simple example. > > Uday Venkatadri > > ------------------- > > var x1, >= 0; > var x2, >= 0; > > maximize > > z: 3*x1+2*x2; > > subject to > > c1: 2*x1+x2 <= 100; > c2: x1+x2 <= 80; > c3: x1 <= 45; > > solve; > > end > > -- View this message in context: http://www.nabble.com/Sensitivity-Information-not-presented-in-sensitivity-bounds-file-tp25968092p25970225.html Sent from the Gnu - GLPK - Bugs mailing list archive at Nabble.com. _______________________________________________ Bug-glpk mailing list Bug-glpk@gnu.org http://lists.gnu.org/mailman/listinfo/bug-glpk
