GRBCallback::setSolution()
Import solution values for a heuristic solution. Only available when
the where member variable is equal to GRB_CB_MIPNODE.
When you specify a heuristic solution from a callback, variables
initially take undefined values. You should use this method to
specify variable values. You can make multiple calls to
setSolution from one callback invocation to specify values for
multiple sets of variables. After the callback, if values
have been specified for any variables, the Gurobi optimizer will try
to compute a feasible solution from the specified values, possibly
filling in values for variables whose values were left undefined.
You can also optionally call
useSolution
within your callback function
to try to immediately compute a feasible solution from the specified
values.
