      • XPRSuserSolNotifyEvent

        void XPRSuserSolNotifyEvent​(XPRSprob cbprob,
                            java.lang.Object cbdata,
                            java.lang.String solname,
                            int status)
        Handle a UserSolNotify event. More details about UserSolNotify events can be found in the documentation of the corresponding C callback.
        Parameters:
        cbprob - The problem passed to the callback function, usersolnotify.
        cbdata - The user-defined data passed as data when setting up the callback.
        solname - The string name assigned to the solution when it was loaded into the Optimizer using addMipSol.
        status - One of the following status values:
        • 1: Solution is feasible. (XPRS_USERSOLSTATUS_ACCEPTED_FEASIBLE)
        • 2: Solution is feasible after reoptimizing with fixed MIP entities. (XPRS_USERSOLSTATUS_ACCEPTED_OPTIMIZED)
        • 3: A local search heuristic was applied and a feasible solution discovered. (XPRS_USERSOLSTATUS_SEARCHED_SOL)
        • 4: A local search heuristic was applied but a feasible solution was not found. (XPRS_USERSOLSTATUS_SEARCHED_NOSOL)
        • 5: Solution is infeasible and a local search could not be applied. (XPRS_USERSOLSTATUS_REJECTED_INFEAS_NOSEARCH)
        • 6: Solution is partial and a local search could not be applied. (XPRS_USERSOLSTATUS_REJECTED_PARTIAL_NOSEARCH)
        • 7: Failed to reoptimize the problem with MIP entities fixed to the provided solution. Likely because a time or iteration limit was reached. (XPRS_USERSOLSTATUS_REJECTED_FAILED_OPTIMIZE)
        • 8: Solution is dropped. This can happen if the MIP problem is changed or solved to completion before the solution could be processed. (XPRS_USERSOLSTATUS_DROPPED)
        • 9: The solution is worse than the current MIP cutoff value. (XPRS_USERSOLSTATUS_REJECTED_CUTOFF)
