I'm trying to solve a MIP using Google Or-Tools, but it's showing that the model is infeasible. I'd like to know if there is a convenient way to analyze which constraint or variable bounds are causing the infeasibility of the model. I want to use the built-in methods of Or-Tools only, without using any third-party packages.
