GRBCallback.UseSolution()

Once you have imported solution values using SetSolution, you can optionally call UseSolution in a GRB.Callback.MIPNODE callback to immediately use these values to try to compute a heuristic solution. Alternatively, you can call UseSolution in a GRB.Callback.MIP or GRB.Callback.MIPSOL callback, which will store the solution until it can be processed internally.

double UseSolution ( )

Return value:

The objective value for the solution obtained from your solution values. It equals GRB.INFINITY if no improved solution is found or the method has been called from a callback other than GRB.Callback.MIPNODE as, in these contexts, the solution is stored instead of being processed immediately.
