The first version after IBM acquired ILOG. More parallelism at the root node, deterministic parallel concurrent LP optimization, along with some additional barrier performance improvements and additional tools for diagnosing ill conditioned basis matrices in MIPs.
#IBM ILOG CPLEX OPTIMIZATION STUDIO IDE 64 BIT#
Support for large nonzero counts that require 64 bit indexing, local optima for non-convex QP, and globalization. MIP performance improvements, random seed parameter to address performance variability, remote object, duals for QCPs, deterministic tuning tool.ĭeterministic time limit support, duals for SOCPs, quadratic expression API in Concert, performance improvements across all algorithms, but especially MIP. Support for nonconvex QPs and MIQPs, distributed parallel MIP and more parallelism at the root node for MIPs. Performance improvements (mainly for SOCP, MISOCP, non-convex QP), support for cloud based optimization.

Generic callback, API recorder to facilitate debugging, subMIP control parameters, Download and Go offering.Īutomated Benders decomposition, modeling assistance tool, runseeds command to better assess performance variability. MIP performance improvements and the addition of a generic branching callback to the other generic callbacks introduced in version 12.8.ĭirect support for multiobjective optimization, callback functionality improvement. MIP performance improvements, new 'emphasis mip 5' mode, etc. This has been updated and replicated here for posterity. Prior to IBM acquiring ILOG, the CPLEX team published a release history of CPLEX.
#IBM ILOG CPLEX OPTIMIZATION STUDIO IDE FULL#
The full IBM ILOG CPLEX Optimization Studio consists of the CPLEX Optimizer for mathematical programming, the CP Optimizer for constraint programming, the Optimization Programming Language (OPL), and a tightly integrated IDE. In addition to that AMPL provides an interface to the CPLEX CP Optimizer.

The CPLEX Optimizer is accessible through independent modeling systems such as AIMMS, AMPL, GAMS, OptimJ and TOMLAB. Finally, a stand-alone Interactive Optimizer executable is provided for debugging and other purposes.

Additionally, connectors to Microsoft Excel and MATLAB are provided. There is a Python language interface based on the C interface.

The CPLEX Optimizer has a modeling layer called Concert that provides interfaces to the C++, C#, and Java languages. The IBM ILOG CPLEX Optimizer solves integer programming problems, very large linear programming problems using either primal or dual variants of the simplex method or the barrier interior point method, convex and non-convex quadratic programming problems, and convex quadratically constrained problems (solved via second-order cone programming, or SOCP). CPLEX continues to be actively developed by IBM. This was acquired by ILOG in 1997 and ILOG was subsequently acquired by IBM in January 2009. Bixby and sold commercially from 1988 by CPLEX Optimization Inc. The CPLEX Optimizer was named for the simplex method as implemented in the C programming language, although today it also supports other types of mathematical optimization and offers interfaces other than C. In 2004, the work on CPLEX earned the first INFORMS Impact Prize.
#IBM ILOG CPLEX OPTIMIZATION STUDIO IDE SOFTWARE#
IBM ILOG CPLEX Optimization Studio (often informally referred to simply as CPLEX) is an optimization software package. IBM ILOG CPLEX Optimization Studio Optimize business decisions, develop and deploy optimization models quickly, and create real-world applications to help improve business outcomes. See the ompr website for more information, documentation and examples. It currently only supports linear constraints and objective functions. The model is solver-independent and thus offers the possibility to solve a model with different solvers. Model mixed integer linear programs in an algebraic way directly in R.
