GRBCallback.useSolution()
Once you have imported solution values using
setSolution,
you can optionally call useSolution in a GRB.CB_MIPNODE callback
to immediately use these values to try to compute a heuristic solution.
Alternatively, you can call useSolution in a GRB.CB_MIP or
GRB.CB_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.CB_MIPNODE as, in these contexts, the solution is stored instead of being processed immediately.
