What can CPLEX optimizer do for businesses?

Model business issues mathematically and solve them with IBM ILOG CPLEX Optimizer's powerful algorithms to produce precise and logical decisions. IBM ILOG CPLEX Optimizer's mathematical programming technology enables decision optimization for improving efficiency, reducing costs, and increasing profitability.

CPLEX Optimizer provides flexible, high-performance mathematical programming solvers for linear programming, mixed integer programming, quadratic programming, and quadratically constrained programming problems. These solvers include a distributed parallel algorithm for mixed integer programming to leverage multiple computers to solve difficult problems.

CPLEX Optimizer automatically determines "smart" settings for a wide range of algorithm parameters, usually resulting in optimal mathematical programming solution performance. A wide variety of input/output options are supported including Log files, Solution files in XML format and  Problem files like: read/write MPS files, IBM ILOG CPLEX Optimizer LP files, MPS basis files, binary problem/basis files. Each message type can be directed to specified files, or completely suppressed.
