Description

Decides how often to apply the periodic heuristic. Setting the value to -1 turns off the periodic heuristic. Setting the value to 0 (zero), the default, applies the periodic heuristic at an interval chosen automatically. Setting the value to a positive number applies the heuristic at the requested node interval. For example, setting this parameter to 20 dictates that the heuristic be called at node 0, 20, 40, 60, etc.
