Procedure GMP::Solution::RetrieveFromSolverSession(solverSession, solution)

GMP::Solution::RetrieveFromSolverSession

The procedure GMP::Solution::RetrieveFromSolverSession stores the solution from a solver session into the solution repository of a generated mathematical program.

GMP::Solution::RetrieveFromSolverSession(
     solverSession,  ! (input) a solver session
     solution        ! (input) a solution
     )

Arguments

solverSession
An element in the set AllSolverSessions.

solution
An integer scalar reference to a solution.

The procedure returns 1 on success, or 0 otherwise.

Note

For a solver session belonging to a GMP with type MIP, this procedure retrieves the best integer solution found by so far (i.e., the incumbent), except when this procedure is called inside a branch, cut, heuristic or lazy constraint callback. In that case this procedure retrieves the LP solution of the current node (branch, cut, heuristic) or an integer feasible solution (lazy constraint).
The function GMP::SolverSession::GetNodeObjective can be used to get the objective value corresponding to the solution retrieved with this procedure inside a branch, candidate, cut, heuristic or lazy constraint callback.
By using the procedure GMP::SolverSession::RejectIncumbent the incumbent solution can be rejected inside a candidate callback.
