[Scip] LP solution status SCIP_LPSOLSTAT_OBJLIMIT

[Grit Claßen]

Hello,

during my Branch-and-Price algorithm I would like to use the current LP 
solution for the calculation of a lower bound. Though, I observed that 
the LP solution is sporadically set to infinity. In these cases, the LP 
solution status is "SCIP_LPSOLSTAT_OBJLIMIT". Searching the SCIP code, I 
realized that the LP solution is set to infinity as soon as the LP 
solution exceeds the objective limit. However, I do not set a limit on 
the objective value. This is why I do not understand the LP solution status.

Can anyone explain what is going on here?

Thanks and best wishes,
Grit
