CPLEX

From Wikipedia, the free encyclopedia

CPLEX is an optimization software package. It was originally developed by Robert E. Bixby and sold via CPLEX Optimization Inc., which was acquired by ILOG, Inc. in 1997. CPLEX solves integer programming and very large linear programming problems and has recently added quadratic programming. 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 Award.
