In the LEMON graph library (http://lemon.cs.elte.hu/) there is an LP solver interface. The LP constraints could be added like the next formulation: lp.addRow((double) <= (Lp::Expr) <= (double)); For example: Lp::Col x1, x2, x3; lp.addRow(2 <= 2 * x1 + 3 * x2 - 2 * x3 <= 8); Because the C++ allows overriding every operator, it looks like a good solution for define range constraints. However, if the -Wparentheses or -Wall is defined, it emits warnings. For the C language, the warning is a proper behavior, but the C++ has boolean type, so rather the bool-numeric comparisons should be warned. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36921
