PipsTerminationStatus

enum PipsTerminationStatus

the termination status of a PIPS-IPM++ solve

Enumerator
PIPS_SUCCESSFUL_TERMINATION	the solver terminated successfully and an optimal solution is available
PIPS_NOT_FINISHED	the solver terminated without finished solving
PIPS_MAX_ITS_EXCEEDED	the iteration limit has been reached
PIPS_TIMELIMIT	the time limit has been reached
PIPS_INFEASIBLE	the solver terminated successfully and concluded that the problem is infeasible
PIPS_UNBOUNDED	the solver terminated successfully and concluded that the problem is unbounded
PIPS_READ_ERROR	there was an error setting up the problem
PIPS_DID_NOT_RUN	the solver did not actually run
PIPS_STOPPED_AFTER_PRESOLVE	the solver stopped after presolve (option STOP_AFTER_PRESOLVE was enabled)
PIPS_SLOW_CONVERGENCE	the solver stopped because convergence was slow (see also option IPM_SLOW_CONVERGENCE_ITER)
PIPS_NUMERICAL	the solver stopped due to numerical issues (see also option IPM_SLOW_CONVERGENCE_ITER)
