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
There is no example of how to call them.
Does someone know how to evaluate solution quality?
