0 
XPRS_SLPSTATUS_CONVERGEDOBJUCC Converged on objective function with no unconverged values in active constraints.
1 
XPRS_SLPSTATUS_CONVERGEDOBJSBX Converged on objective function with some variables converged on extended criteria only.
2 
XPRS_SLPSTATUS_LPINFEASIBLE LP solution is infeasible.
3 
XPRS_SLPSTATUS_LPUNFINISHED LP solution is unfinished (not optimal or infeasible).
4 
XPRS_SLPSTATUS_MAXSLPITERATIONS SLP terminated on maximum SLP iterations.
5 
XPRS_SLPSTATUS_INTEGERINFEASIBLE SLP is integer infeasible.
6 
XPRS_SLPSTATUS_RESIDUALPENALTIES SLP converged with residual penalty errors.
7 
XPRS_SLPSTATUS_CONVERGEDOBJOBJ Converged on objective.
9 
XPRS_SLPSTATUS_MAXTIME SLP terminated on max time.
10 
XPRS_SLPSTATUS_USER SLP terminated by user.
11 
XPRS_SLPSTATUS_VARSLINKEDINACTIVE Some variables are linked to active constraints.
12 
XPRS_SLPSTATUS_NOVARSINACTIVE No unconverged values in active constraints.
13 
XPRS_SLPSTATUS_OTOL OTOL is satisfied - range of objective change small, active step bounds.
14 
XPRS_SLPSTATUS_VTOL VTOL is satisfied - range of objective change is small.
15 
XPRS_SLPSTATUS_XTOL XTOL is satisfied - range of objective change small, no unconverged in active.
16 
XPRS_SLPSTATUS_WTOL WTOL is satisfied - convergence continuation.
17 
XPRS_SLPSTATUS_ERROTOL ERRORTOL satisfied - penalties not increased further.
18 
XPRS_SLPSTATUS_EVTOL EVTOL satisfied - penalties not increased further.
19 
XPRS_SLPSTATUS_POLISHED There were iterations where the solution had to be polished.
20 
XPRS_SLPSTATUS_POLISH_FAILURE There were iterations where the solution polishing failed.
21 
XPRS_SLPSTATUS_ENFORCED There were iterations where rows were enforced.
22 
XPRS_SLPSTATUS_CONSECUTIVE_INFEAS Terminated due to SLPINFEASLIMIT.
Note
A value of zero after SLP optimization means that the solution is fully converged.
