Debugging unsolved optimizations #22

Hi

Thanks for this repository! You're doing a great job. Could you help me figure out how to access functions related to unsolved constraints?

This Gurobi example shows an IIS that can be run to figure out conflicting constraints, although I'm not able to find this object within the rsome wrapper.

Hi Thank you for your interest in RSOME. I think checking the unsolved/conflicting constraints is at the solution stage, so RSOME as a pure modeling toolbox, does not provide such functions.

However, there might be an indirect way to check the unsolved constraints built by RSOME. Please check our website https://xiongpengnus.github.io/rsome/get_start#section1.3: we provide a to_lp() method, which exports an ".lp" file. You could use Gurobi to read the lp file and analyze the unsolved constraints.

Thank you! I will try that.
