 A novel parallel UCT algorithm with linear speedup and negligible performance loss. This package provides a demo on Atari games (see [Running](#Running)). To allow easy extension to other environments, we wrote the code in an extendable way, and modification on only two files are needed for other environments (see [Run on your own environments](#Run-on-your-own-environments)).
