Each of the optimizers available in 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 CPLEX optimizers, as we suggested in Choosing an Optimizer for Your LP Problem. The following sections describe other features of CPLEX to consider in tuning the performance of your application:

• Preprocessing: Presolver and Aggregator

• Preprocessing: Explicitly Solving the Dual

• Starting from an Advanced Basis

• Adjusting Parameters
