The XPRESS Solver Options dialog Heuristics tab allows you to control the frequency and nature of heuristic methods used to find an integer solution early in the Branch & Cut search.

On this tab, you can choose the heuristics Strategy (None, Rounding or Automatic), the Frequency and Maximum Depth in the tree at which heuristics will be applied, and the Maximum Nodes explored and Maximum Solutions found while heuristics are used.
