def LoadSolutionFromProto(self, *args) -> "absl::Status":
r"""
Load a solution encoded in a protocol buffer onto this solver for easy
access via the MPSolver interface.
IMPORTANT: This may only be used in conjunction with ExportModel(),
following this example:
.. code-block:: c++
MPSolver my_solver;
... add variables and constraints ...
MPModelProto model_proto;
my_solver.ExportModelToProto(model_proto);
MPSolutionResponse solver_response;
MPSolver::SolveWithProto(model_proto, solver_response);
if (solver_response.result_status() == MPSolutionResponse::OPTIMAL) {
CHECK_OK(my_solver.LoadSolutionFromProto(solver_response));
... inspect the solution using the usual API: solution_value(), etc...
}
The response must be in OPTIMAL or FEASIBLE status.
Returns a non-OK status if a problem arised (typically, if it wasn't used
like it should be):
- loading a solution whose variables don't correspond to the solver's
current variables
- loading a solution with a status other than OPTIMAL / FEASIBLE.
Note: the objective value isn't checked. You can use VerifySolution() for
that.
