Cplex 11 user manual

This part of the manual collects topics about each of the application programming interfaces (APIs) available for IBM ILOG CPLEX. It is not necessary to read each of these topics thoroughly. In fact, most users will concentrate only on the topic about the API that they plan to . ILOG CPLEX User's Manual Advanced Programming Techniques Using Optimization Callbacks: Using Optimization Callbacks: INDEX PREVIOUS NEXT: This chapter introduces optimization callbacks. Callbacks allow you to monitor closely and to guide the behavior of ILOG CPLEX optimizers. In particular, ILOG CPLEX callbacks allow user code to be. This information is hidden within the user's problem (in the CPLEX LP problem object, for Callable Library users) and was inaccessible to the user in CPLEX releases prior to The presolve process for a mixed integer program is similar, but has a few important differences. First, the actual presolve reductions differ.

While presolve was a highly automated and transparent procedure in releases of CPLEX prior to , releases and above give the user significant control over when presolve is performed and what is done with the result. This section discusses these added control facilities. ILOG CPLEX User's Manual Discrete Optimization Solving Mixed Integer Programming Problems (MIP) Troubleshooting MIP Performance Problems. In particular, ILOG CPLEX callbacks allow user code to be executed regularly during an optimization or during a tuning session. To use callbacks (either optimization or tuning callbacks) with ILOG CPLEX, you must first write the callback function, and then pass it to ILOG CPLEX.
