CPLEX

CPLEX is an optimization software package. It is named for the simplex method and the C programming language, although today it contains interior point methods and interfaces in the Java and C++ languages. It was originally developed by Robert E. Bixby and sold via CPLEX Optimization Inc., which was acquired by ILOG in 1997. CPLEX solves integer programming, very large^[1] linear programming problems, quadratic programming and has recently added support for convex quadratic constraints. It has a modeling layer called Concert and is also available with several modeling systems like AIMMS, AMPL, GAMS and OPL Development Studio.

In 2004, the work on CPLEX earned the first INFORMS Impact Prize.
