Description
Controls the MIP dive strategy. The MIP traversal strategy occasionally performs probing dives, where it looks ahead at both children nodes before deciding which node to choose. The default (automatic) setting lets CPLEX choose when to perform a probing dive, 1 (one) directs CPLEX never to perform probing dives, 2 always to probe, 3 to spend more time exploring potential solutions that are similar to the current incumbent. Setting 2, always to probe, is helpful for finding integer solutions.
