Human-readable status response

In the new multiobjective optimization support in CPLEX (Java API, but likely true in other APIs), querying status via IloCplex.getMultiObjInfo(IloCplex.MultiObjIntInfo.MultiObjStatus, ...) returns a numeric code (e.g. 107). This is difficult to interpret.

  • Future consideration
Who would benefit from this IDEA? Users developing multiobjective optimization code using one of the CPLEX APIs would benefit by getting more easily interpretable results.
How should it work?

Option 1: Have it work the same way IloCplex.getStatus() does (returning IloCplex.Status). This might require splitting it off to a separate method from other targets of IloCplex.getMultiObjInfo() that return integers.

Option 2: Provide a method in IloCplex to convert a numeric code (101, 107, ...) into a CplexStatus value.

Idea Priority Medium
Priority Justification It's a bit of a "niche" issue (applies only if you are doing multiobjective optimization and trying to get status information).
