You may either introduce additional variables and corresponding equality constraints: var x_a; var x_b; s.t. foo: x_a = x * a; s.t. bar: x_b = x * b; Or, that is better, use the printf statement: ... solve; /* <- this statement should be specified */ printf "x * a = %g; x * b = %g\n", x * a, x * b; ... _______________________________________________ Help-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-glpk
