Description

Sets the search strategy for a mixed integer program (MIP). By default, CPLEX chooses whether to apply dynamic search or conventional branch and cut based on characteristics of the model and the presence (or absence) of callbacks.

To benefit from dynamic search, a MIP must not include control callbacks (that is, callbacks that alter the search path through the solution space). In other words, control callbacks are not compatible with dynamic search. These control callbacks are identified as advanced in the reference manuals of the APIs. If control callbacks are present in your application, CPLEX will disable dynamic search, issue a warning, and apply only static branch and cut. If you want to control the search yourself, for example, through advanced control callbacks, then you should set this parameter to 1 (one) to disable dynamic search and to apply conventional branch and cut.
