CPX_STAT_MULTIOBJ_STOPPED

The solve of a multi-objective problem was interrupted.

For a multi-objective MIP, CPLEX returns CPX_STAT_MULTIOBJ_STOPPED in three cases. The first one arises when a global work limit imposed by the user (such, e.g., a deterministic time limit) was hit during the solution process, or when the solution process was aborted by the user. The second one arises when a local work limit imposed by the user was hit during the solution of any of the MIP sub-problems and CPLEX did not find any feasible solution for that sub-problem before hitting the limit. The third one arises when CPLEX encounters an error or a failure during the solution process of one of the MIP sub-problems. In the latter case, CPXmultiobjopt will return an error status indicating the reason of the failure.

For a multi-objective LP, CPLEX returns CPX_STAT_MULTIOBJ_STOPPED in two cases. The first one arises when a global or a local work limit imposed by the user (such, e.g., a deterministic time limit) was hit during the solution process, or when the solution process was aborted by the user. The second one arises when CPLEX encounters an error or a failure during the solution process of one of the LP sub-problems. In the latter case, CPXmultiobjopt will return an error status indicating the reason of the failure.
