Re: Clobber - 2020 Computer Olympiad

Hi,

Yes, I am very interested.

Do you have a protocol for automatic play?

Re: AlphaZero approach for card games

Hi Alvaro, Because of hidden information, methods that work for board games usually don't work well for card games. The AlphaZero method itself may not work well, but other machine learning algorithms based on self play have been successfully applied to card games. The main approach for statistical ...

Polygames: Improved Zero Learning

github: https://github.com/facebookincubator/polygames paper: https://arxiv.org/abs/2001.09832 abstract: Since DeepMind's AlphaZero, Zero learning quickly became the state-of-the-art method for many board games. It can be improved using a fully convolutional structure (no fully connected layer). Usi...

Ataxx in Ludii

Hi,

Ataxx is included in the latest version of Ludii. You can get it from there:
https://ludii.games/download.php

Menu: File/Load Game -> Games/board/space/territory/Ataxx

The GUI lets you play against an UCT player. I played a game, and won easily.

The alphabeta player is much stronger.

TD(1)

I'll try to explain TD(1) as simply as possible. The idea is to tune the evaluation function so that it predicts game outcomes as accurately as possible. Depending on the game, the nature of the game outcome might be a bit different. Some Othello programs try to predict and maximize the final score....

My home-made CUDA kernel for convolutions

Hi, I wrote a CUDA kernel for convolution, and it outperforms cuDNN for small tensors. cuDNN is efficient for large batches, but slow for small batches. Here are some numbers for my Go program. This is a network with 80 layers of 128 channels, 19x19 board, V100 (PCIExpress), half-precision, NHWC ten...

Crazy Zero

Hi, Here is a short report about my Crazy Zero experiments. Crazy Zero is a generic implementation of AlphaZero. I already used it for Go, shogi, gomoku, renju, othello, and chess. The version that played on the Ataxx server (http://server.ataxx.org/) is less than one day old. The network architectu...
