    • Method Detail

      • hasModel

        boolean hasModel()
         The model to be optimized by the server.
        optional .operations_research.MPModelProto model = 1;
        Returns:
        Whether the model field is set.

      • getModel

        MPModelProto getModel()
         The model to be optimized by the server.
        optional .operations_research.MPModelProto model = 1;
        Returns:
        The model.

      • getModelOrBuilder

        MPModelProtoOrBuilder getModelOrBuilder()
         The model to be optimized by the server.
        optional .operations_research.MPModelProto model = 1;

      • hasSolverType

        boolean hasSolverType()
        optional .operations_research.MPModelRequest.SolverType solver_type = 2 [default = GLOP_LINEAR_PROGRAMMING];
        Returns:
        Whether the solverType field is set.

      • getSolverType

        MPModelRequest.SolverType getSolverType()
        optional .operations_research.MPModelRequest.SolverType solver_type = 2 [default = GLOP_LINEAR_PROGRAMMING];
        Returns:
        The solverType.

      • hasSolverTimeLimitSeconds

        boolean hasSolverTimeLimitSeconds()
         Maximum time to be spent by the solver to solve 'model'. If the server is
 busy and the RPC's deadline_left is less than this, it will immediately
 give up and return an error, without even trying to solve.

 The client can use this to have a guarantee on how much time the
 solver will spend on the problem (unless it finds and proves
 an optimal solution more quickly).

 If not specified, the time limit on the solver is the RPC's deadline_left.
        optional double solver_time_limit_seconds = 3;
        Returns:
        Whether the solverTimeLimitSeconds field is set.

      • getSolverTimeLimitSeconds

        double getSolverTimeLimitSeconds()
         Maximum time to be spent by the solver to solve 'model'. If the server is
 busy and the RPC's deadline_left is less than this, it will immediately
 give up and return an error, without even trying to solve.

 The client can use this to have a guarantee on how much time the
 solver will spend on the problem (unless it finds and proves

        optional double solver_time_limit_seconds = 3;
        Returns:
        The solverTimeLimitSeconds.

      • hasEnableInternalSolverOutput

        boolean hasEnableInternalSolverOutput()
         If this is set, then EnableOutput() will be set on the internal MPSolver
 that solves the model.
 WARNING: if you set this on a request to prod servers, it will be rejected
 and yield the RPC Application Error code MPSOLVER_SOLVER_TYPE_UNAVAILABLE.
        optional bool enable_internal_solver_output = 4 [default = false];
        Returns:
        Whether the enableInternalSolverOutput field is set.

      • getEnableInternalSolverOutput

        boolean getEnableInternalSolverOutput()
         If this is set, then EnableOutput() will be set on the internal MPSolver
 that solves the model.
 WARNING: if you set this on a request to prod servers, it will be rejected
 and yield the RPC Application Error code MPSOLVER_SOLVER_TYPE_UNAVAILABLE.
        optional bool enable_internal_solver_output = 4 [default = false];
        Returns:
        The enableInternalSolverOutput.

      • hasSolverSpecificParameters

        boolean hasSolverSpecificParameters()
         Advanced usage. Solver-specific parameters in the solver's own format,
 different for each solver. For example, if you use SCIP and you want to
 stop the solve earlier than the time limit if it reached a solution that is
 at most 1% away from the optimal, you can set this to "limits/gap=0.01".

 Note however that there is no "security" mechanism in place so it is up to
 the client to make sure that the given options don't make the solve
 non thread safe or use up too much memory for instance.

 If the option format is not understood by the solver, the request will be
 rejected and yield an RPC Application error with code
 MPSOLVER_MODEL_INVALID_SOLVER_PARAMETERS, unless you have set
 ignore_solver_specific_parameters_failure=true (in which case they are
 simply ignored).
        optional string solver_specific_parameters = 5;
        Returns:
        Whether the solverSpecificParameters field is set.

      • getSolverSpecificParameters

        java.lang.String getSolverSpecificParameters()

         Controls the recovery of additional solutions, if any, saved by the
