Scott Martin (co-driver)

Scott Martin is a British rallying co-driver who competes in the FIA World Rally Championship. Martin began his rallying career in 2001 co-driving at a national level in the UK. With Matthew Wilson in 2004, he finished as second outright co-driver in the British Rally Championship in the Ford Focus RS. After the 2004 season, Martin was accepted into the MSA British Rally Elite Scheme, a specialist training scheme for young British rally drivers. In 2005 he was involved in a serious accident on the opening round of the BRC, the Rally of Wales, was airlifted to hospital; that year he achieved his first international win on the Trackrod Rally with Wilson. The team finished first on the Colin McRae Stages Rally. In 2006 Martin, with Scottish driver Barry Clark in the Ford Fiesta ST, scored third place in the Fiesta Sporting Trophy International series and third place in the S1600 category of the BRC; the following year he achieved his first win in an international series in the FSTi with Clark, with Mark Higgins he was placed overall third in the FIA Production World Rally Championship.

Throughout the period 2008-2011 he co-drove with Matthew Wilson in the Ford Focus RS and Ford Fiesta RS, competing in the full WRC series. The pair achieved seventh place in the overall classification in 2009 and again in 2011, when they were placed fourth in the Repco Rally Australia, his best WRC result, he participated in only two WRC events in 2012 in 2013 competed as co-driver with Sheikh Khalid Al-Qassimi in the Citroen DS3. The team took part in 7 WRC events, in five Middle East Rally Championship events, in which they were placed second overall. At the end of 2013 Martin had competed in 82 WRC rallies, he stood 13th in the IRDA ranking of co-drivers, with 2844 points, making him the highest-placed British co-driver. In 2014 he and Craig Breen won the Acropolis Rally in Greece - removed that year from the list of FIA championships – driving the Peugeot 208 T16, the Ravens Rock Rally in Ireland driving the Ford Fiesta RS. * Season still in progress.

Leela Chess Zero

Leela Chess Zero is a free, open-source, neural network-based chess engine and distributed computing project. Development has been spearheaded by programmer Gary Linscott, a developer for the Stockfish chess engine. Leela Chess Zero was adapted from the Leela Zero Go engine, which in turn was based on Google's AlphaGo Zero project to verify the methods in the AlphaZero paper as applied to the game of chess. Like Leela Zero and AlphaGo Zero, Leela Chess Zero starts with no intrinsic chess-specific knowledge other than the basic rules of the game. Leela Chess Zero learns how to play chess by reinforcement learning from repeated self-play, using a distributed computing network coordinated at the Leela Chess Zero website; as of August 2019, Leela Chess Zero had played over 232 million games against itself, is capable of play at a level, comparable with Stockfish, the leading conventional chess program. The Leela Chess Zero project was first announced on TalkChess.com on January 9, 2018. This revealed Leela Chess Zero as the open-source, self-learning chess engine it would come to be known as, with a goal of creating a strong chess engine.

Within the first few months of training, Leela Chess Zero had reached the Grandmaster level, surpassing the strength of early releases of Rybka and Komodo, despite evaluating orders of magnitude fewer positions while using MCTS. In December 2018, the AlphaZero team published a new paper in Science magazine revealing undisclosed details of the architecture and training parameters used for AlphaZero; these changes were soon incorporated into Leela Chess Zero and increased both its strength and training efficiency. The work on Leela Chess Zero has informed the similar AobaZero project for shogi; the method used by its designers to make Leela Chess Zero self-learn and play chess at above human level is reinforcement learning. This is a machine-learning algorithm, mirrored from AlphaZero to be used by Leela Chess Zero, to maximize reward to make the engine a better chess player through self-play. From open-source, Leela Chess Zero has played hundreds of millions of games, run by volunteer users, in order to learn with the reinforcement algorithm.

In order to contribute to the advancement of the Leela Chess Zero engine, the latest version of the Engine as well as the Client must be downloaded. The Client is needed to connect to the current server of Leela Chess Zero, which all of the information from the self-play chess games are stored, to obtain the latest network, generate self-play games, upload the training data back to the server. If, someone would like themselves to play against Leela Chess Zero engine, the network must be downloaded; the network contains Leela Chess Zero's evaluation function, needed for the opponent to play against the engine. Playing against a past form of the Leela Chess Zero engine is possible, although the self-play rating calculated for the engine is different from the conventional Elo chess rating. In order to find the self-play rating of Leela Chess Zero from Elo rating is to use the formula: X = /0.6 where y is the players Elo chess rating, X is Leela Chess Zero's self-play rating. In April 2018, Leela Chess Zero became the first neural network engine to enter the Top Chess Engine Championship, during season 12 in the lowest division, division 4.

Leela did not perform well: in 28 games, it won one, drew two, lost the remainder. However, it improved quickly. In July 2018, Leela placed seventh out of eight competitors at the 2018 World Computer Chess Championship. In August 2018, it won division 4 of TCEC season 13 with a record of 14 wins, 12 draws, 2 losses. In Division 3, Leela scored 16/28 points, finishing third behind Ethereal, who scored 22.5/28 points, Arasan on tiebreak. By September 2018, Leela had become competitive with the strongest engines in the world. In the 2018 Chess.com Computer Chess Championship, Leela placed fifth out of 24 entrants. The top eight engines advanced to round 2. Leela won the 30-game match against Komodo to secure third place in the tournament. Concurrently, Leela participated in the TCEC cup, a new event in which engines from different TCEC divisions can play matches against one another. Leela defeated higher-division engines Laser and Fire before being eliminated by Stockfish in the semi-finals. In October and November 2018, Leela participated in the Chess.com Computer Chess Championship Blitz Battle.

Leela finished third behind Komodo. In December 2018, Leela participated in season 14 of the Top Chess Engine Championship. Leela dominated divisions 3, 2, 1 finishing first in all of them. In the premier division, Stockfish dominated while Houdini and Leela competed for second place, it came down to a final-round game where Leela needed to hold Stockfish to a draw with black to finish second ahead of Komodo. It managed this and therefore contested the superfinal against Stockfish, it narrowly lost the superfinal against Stockfish with a 49.5-50.5 final score. In February 2019, Leela scored its first major tournament win when it defeated Houdini in the final of the second TCEC cup. Leela did not lose a game the entire tournament. In April 2019, Leela won the Chess.com Computer Chess Championship 7: Blitz Bonanza, becoming the first neural-network project to take the title. In May 2019, Leela defended its TCEC cup title, this time defeating Stockfish in the final 5.5-4.5 after Stockfish blundered a 7-man tablebase draw.

Leela won the Superfinal of season 15 of the Top Chess Engine Championship 53.5-46.5 versus Stockfish. Sea
