Improve efficiency, quickly implement strategies and increase profitability. ILOG CPLEX\’s mathematical optimization technology enables better decision-making for efficient resource utilization. With ILOG CPLEX, complex business problems can be represented as mathematical programming models. Advanced optimization algorithms allow you to rapidly find solutions to these models. Today, over 1,300 corporations and government agencies use ILOG CPLEX, along with researchers at over 1,000 universities. ILOG CPLEX helps solve planning and scheduling problems in virtually every industry. More than 100 of the world\’s leading software companies are also ILOG CPLEX customers, including market leaders like SAP, Oracle and Sabre. Robust algorithms for demanding problems ILOG pioneered the development of the algorithms needed to solve today\’s most demanding mathematical optimization problems. ILOG CPLEX has...

The Gurobi Optimizer is a state-of-the-art simplex based linear programming (LP) and mixed-integer programming (MIP) solver, built from the ground up to exploit modern multi-core processors. Parallelism is included with every Gurobi license. The Gurobi Parallel MIP Optimizer is deterministic: two separate runs on the same model will produce identical solution paths. Gurobi is also available through several powerful third-party modeling systems including AIMMS, AMPL, FRONTLINE SOLVERS, GAMS, MPL, OptimJ, and TOMLAB. Version 2.0 of the Gurobi Optimizer includes a number of enhancements: * Significant improvements in MIP performance: For difficult models, Gurobi 2.0 is roughly four times as fast as Gurobi 1.1. * Significant improvements in simplex performance: The new dual simplex optimizer is roughly twice as fast as...
