There is a way to evaluate the solution quality in CPLEX which is getting a kappa value. I have been trying getting this with CPX\_PARAM\_MIPKAPPASTATS command with the following line:

m = Model(with\_optimizer(CPLEX.Optimizer,CPX\_PARAM\_MIPKAPPASTATS=2))

When I solved the problem m I cannot get anything new with that command.

There are others command to get the kappa value but I cannot reach the value with any of them.

The kappa parameters are defined in the next script:  
[https://github.com/JuliaOpt/CPLEX.jl/blob/master/src/full\_defines\_1280.jl](https://github.com/JuliaOpt/CPLEX.jl/blob/master/src/full_defines_1280.jl)

There is no example of how to call them.

Does someone know how to evaluate solution quality?
