Each of the optimizers available in ILOG CPLEX is designed to solve most linear programming problems under its default parameter settings. However, characteristics of your particular problem may make performance tuning advantageous.

As a first step in tuning performance, try the different ILOG CPLEX optimizers, as we suggested in Choosing an Optimizer for Your LP Problem. The following sections describe other features of ILOG CPLEX to consider in tuning the performance of your application:

• Preprocessing
• Starting from an Advanced Basis
• Simplex Parameters
