About The Project

This repository implements KL Game, an algorithm for solving non-cooperative dynamic game with Kullback-Leibler (KL) regularization with respect to a general, stochastic, and possibly multi-modal reference policy. The repository is primarily developed and maintained by Haimin Hu, Justin Lidard, and Zixu Zhang.

Examples

Policy blending: car racing

We provide a car racing example in the Notebook to showcase the policy blending feature of KL Game. This Notebook comprises three sections, each dedicated to a closed-loop simulation using a different method: basic KL Game, multi-modal KL Game, and multi-modal reference policy.
