ILOG 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, OPL Development Studio and OptimJ.
