'''LEMON''' stands for '''L'''ibrary for '''E'''fficient '''M'''odeling and '''O'''ptimization in '''N'''etworks.
It is a C++ template library providing efficient implementations of common data structures and algorithms with focus on combinatorial optimization tasks connected mainly with graphs and networks.

'''LEMON''' is a member of the '''[http://www.coin-or.org/ COIN-OR initiative]''', a collection of [WikiPedia:Operations_Research OR] related [http://opensource.org/ open source] projects. You are free to use it in your commercial or non-commercial applications under very permissive [wiki:License license terms].

The project was launched by the [http://www.cs.elte.hu/egres/ Egerváry Research Group on Combinatorial Optimization (EGRES)] at the Department of Operations Research, Eötvös Loránd University, Budapest, Hungary in 2003. Up to this point, the developers of the library work at the [http://www.elte.hu/en/ Eötvös Loránd University, Budapest] and at the [http://portal.bme.hu/langs/en/default.aspx Budapest University of Technology and Economics].
