USERSOLHEURISTIC

Determines how much effort to put into running a local search heuristic to find a feasible integer solution from a partial or infeasible user solution.

Integer

-1	Automatically determined.
0	Search heuristic disabled.
1	Light effort.
2	Moderate effort.
3	High effort.

-1

When a partial or infeasible user solution is added with XPRSaddmipsol, a local search heuristic will be applied to the problem in an attempt to find a feasible, integer solution that either completes the partial solution or is close to the infeasible solution. Whether to run such a heuristic, or how much effort to put into the heuristic can be controlled by this USERSOLHEURISTIC parameter.
