Five divisions, each of eight engines, played two or more ‘DRR’ double round robin phases each, with promotions and relegations following. Classic tempi gradually lengthened and the Premier division’s top two engines played a 100-game match to determine the Grand Champion. The strategy for the selection of mandated openings was finessed from division to division. -

Chess Engine Using Deep Reinforcement Learning Kamil Klosowski
Chess Engine Using Deep Reinforcement Learning Kamil Klosowski 916847 May 2019 Abstract Reinforcement learning is one of the most rapidly developing areas of Artificial Intelligence. The goal of this project is to analyse, implement and try to improve on AlphaZero architecture presented by Google DeepMind team. To achieve this I explore different architectures and methods of training neural networks as well as techniques used for development of chess engines.

Crafty 12.6 finds the correct sacrifice too, though it needs to search to 10 ply, instead of the 7 plies required by CG1.0, but its better hardware makes for the shortest time. -
Draft – Not for Circulation
A Gross Miscarriage of Justice in Computer Chess by Dr. Søren Riis Introduction In June 2011 it was widely reported in the global media that the International Computer Games Association (ICGA) had found chess programmer International Master Vasik Rajlich in breach of the ICGA‟s annual World Computer Chess Championship (WCCC) tournament rule related to program originality. In the ICGA‟s accompanying report it was asserted that Rajlich‟s chess program Rybka contained “plagiarized” code from Fruit, a program authored by Fabien Letouzey of France. Some of the headlines reporting the charges and ruling in the media were “Computer Chess Champion Caught Injecting Performance-Enhancing Code”, “Computer Chess Reels from Biggest Sporting Scandal Since Ben Johnson” and “Czech Mate, Mr. Cheat”, accompanied by a photo of Rajlich and his wife at their wedding. In response, Rajlich claimed complete innocence and made it clear that he found the ICGA‟s investigatory process and conclusions to be biased and unprofessional, and the charges baseless and unworthy. He refused to be drawn into a protracted dispute with his accusers or mount a comprehensive defense. This article re-examines the case. With the support of an extensive technical report by Ed Schröder, author of chess program Rebel (World Computer Chess champion in 1991 and 1992) as well as support in the form of unpublished notes from chess programmer Sven Schüle, I argue that the ICGA‟s findings were misleading and its ruling lacked any sense of proportion. The purpose of this paper is to defend the reputation of Vasik Rajlich, whose innovative and influential program Rybka was in the vanguard of a mid-decade paradigm change within the computer chess community. -

ChessBase.com - Chess News - Grandmasters and Global Growth Grandmasters and Global Growth 07.01.2010 Professor Kenneth Rogoff is a strong chess grandmaster, who also happens to be one of the world's leading economists. In a Project Syndicate article that appeared this week Ken sees the new decade as one in which "artificial intelligence hits escape velocity," with an economic impact on par with the emergence of India and China. He uses computer chess to illustrated the point. Grandmasters and Global Growth By Kenneth Rogoff As the global economy limps out of the last decade and enters a new one in 2010, what will be the next big driver of global growth? Here’s betting that the “teens” is a decade in which artificial intelligence hits escape velocity, and starts to have an economic impact on par with the emergence of India and China. Admittedly, my perspective is heavily colored by events in the world of chess, a game I once played at a professional level and still follow from a distance. Though special, computer chess nevertheless offers both a window into silicon evolution and a barometer of how people might adapt to it. A little bit of history might help. In 1996 and 1997, World Chess Champion Gary Kasparov played a pair of matches against an IBM computer named “Deep Blue.” At the time, Kasparov dominated world chess, in the same way that Tiger Woods – at least until recently – has dominated golf. In the 1996 match, Deep Blue stunned the champion by beating him in the first game. -

TCEC Cup 2 was nested within TCEC14 (Haworth and Hernandez, 2019c/d) and began on January 17th 2019 with 32 chess engines and only a few minor changes from the inaugural Cup event. The ‘standard pairing’ was again used, with seed s playing seed 26-r-s+1 in round r if the wins all go to the higher seed.
