 ## 0. Overview
 **Fast-Racing** is a strong baseline that focuses on high-quality and extremely aggressive SE(3) trajectory generation. 
 
-The back-end optimization is a parallel extension of [__GCOPTER__](https://github.com/ZJU-FAST-Lab/GCOPTER) for drone racing, powered by [__MINCO__](https://arxiv.org/pdf/2103.00190.pdf) trajectory representation.
