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.

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.
