MIP solution status
Hello, I've been using code like this to get the solution status of a MIP: case getprobstat of XPRS_OPT: status:="Optimum found" XPRS_UNF: status:="Unfinished" XPRS_INF: status:="Infeasib...
The statuses you mentioned are both mapped to XPRS_UNF.
XPRS_MIP_* are values for the MIPSTATUS attribute that you can query directly as described here:
mipstatus := getparam("XPRS_mipstatus")This way you can get the more detailed status information that is specific to MIP. The most detailed information you can get by querying attributes SOLVESTATUS and SOLSTATUS. This tells you why Xpress stopped and what kind of solution is available.
