Enumeration Type Documentation

SCIP solving status

Enumerator
SCIP_STATUS_UNKNOWN 

the solving status is not yet known

SCIP_STATUS_USERINTERRUPT 

the user interrupted the solving process (by pressing CTRL-C)

SCIP_STATUS_NODELIMIT 

the solving process was interrupted because the node limit was reached

SCIP_STATUS_TOTALNODELIMIT 

the solving process was interrupted because the total node limit was reached (incl. restarts)

SCIP_STATUS_STALLNODELIMIT 

the solving process was interrupted because the stalling node limit was reached (no inprovement w.r.t. primal bound)

SCIP_STATUS_TIMELIMIT 

the solving process was interrupted because the time limit was reached

SCIP_STATUS_MEMLIMIT 

the solving process was interrupted because the memory limit was reached

SCIP_STATUS_GAPLIMIT 

the solving process was interrupted because the gap limit was reached

SCIP_STATUS_SOLLIMIT 

the solving process was interrupted because the solution limit was reached

SCIP_STATUS_BESTSOLLIMIT 

the solving process was interrupted because the solution improvement limit was reached

SCIP_STATUS_RESTARTLIMIT 

the solving process was interrupted because the restart limit was reached

SCIP_STATUS_OPTIMAL 

the problem was solved to optimality, an optimal solution is available

SCIP_STATUS_INFEASIBLE 

the problem was proven to be infeasible

SCIP_STATUS_UNBOUNDED 

the problem was proven to be unbounded

SCIP_STATUS_INFORUNBD 

the problem was proven to be either infeasible or unbounded
