Description
Controls whether CPLEX applies a local branching heuristic to try to improve new incumbents found during a MIP search. By default, this parameter is off. If you turn it on, CPLEX will invoke a local branching heuristic only when it finds a new incumbent. If CPLEX finds multiple incumbents at a single node, the local branching heuristic will be applied only to the last one found.
