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 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.
There are three types of optimization callbacks: informational callbacks, query callbacks, and control callbacks. You will find additional information about callbacks in this manual inCallbacks for Tuning and in Advanced MIP Control Interface. This chapter, concentrating on optimization callbacks, includes information about:
