    A program called WEAP (www.weap21.org) uses your codes and is closed-source. Doesn't it against LGPL2?

    Pretty much the BEST open-source LP library and environment. Easy to use, very flexible and fast as well. Integrates very well with Qt 5.4 Thanks for the awesome work

    Excellent costless alternative for Mixed Integer Linear Programming solver. Highly configurable extensions to integrate different file formats.
