# Chess Engine : PVS
## About
This chess AI was developed by [Justin Aubin](https://github.com/Justin-Aubin) and myself for an end-of-term project part of 8INF878 : AI course at UQAC. You can find the written report about this project (in French) in the repo.
It uses the [UCI](http://wbec-ridderkerk.nl/html/UCIProtocol.html) protocol. We implemented :
- principal variation splitting (distributed algorithm)
- depth limited minimax with fail-soft alpha-beta pruning
- material evaluation
- tapered evaluation
- piece square tables
- transposition table
- quiescense search
- move ordering
- opening book (20 000 games)
It can deliver a move in less than a second at depth 5 on most computers. If your computer has lot of cores, you may want to try at depth 7 and modify the 1 second time limit in Timer.java.
Thanks to it we won the small tournament organized between the AI of the students of the class.
This has been possible thanks to [Chesslib](https://github.com/bhlangonijr/chesslib) for the chess rules and [Carballo](https://github.com/albertoruibal/carballo) for the reading of Polyglot files.
## How to use
The repo is a Maven project. Use the IDE of your choice to play with it.
You can play against the AI using the console and [UCI](http://wbec-ridderkerk.nl/html/UCIProtocol.html) commands or build a .JAR file and use it on a Graphical User Interface supporting UCI protocol : [Arena](http://www.playwitharena.de/).
