You can add engine settings files with Python models in your Decision Optimization experiment. A settings file is where you store user-defined values options for mathematical programming, or constraint programming. It gives you access to the solver (engine) parameters so that you can modify them.
Click + and select Add engine settings file in the Build model view. The Visual editor opens where you can see the default parameter values, which are arranged in different categories, that you can customize for your model. You can also search for specific parameters by entering a name in the Find settings search field. You can also add more than one engine settings file.
