Deus X

Home * Engines * Deus X



Deus X (DeusX), a chess playing entity powered by Leela Chess Zero due to Albert Silver to produce (train) and use (during game play) the weights of the convolutional neural network, relaxing the "Zero" paradigm of pure reinforcement learning by supervised learning, that is feeding in high quality games played by other strong chess playing entities.

TCEC Season 13
Deus X controversially participated at TCEC Season 13 together with its ancestor Lc0, but did not meet TCEC's updated uniqueness criteria in subsequent seasons.

PT 54
Deus X further played the PT 54 over the board, running on 2 x Nvidia GeForce RTX 2080 and 8 CPU cores, where it won ahead of Shredder and Jonny, and apparently became the driving force of the commercial ChessBase cloud project Fat Fritz.

WCRCC 2019
In December 2019, DeusX played the Thirteenth Annual ACCA World Computer Rapid Chess Championship (WCRCC 2019) and won the playoff versus Komodo. [Event "WCRCC 2019"] [Site "Internet Chess Club"] [Date "2019.12.08"] [Round "1"] [White "DeusX"] [Black "Komodo"] [Result "1-0"]
