Parallel Chess Searching and Bitboards
Parallel Chess Searching and Bitboards David Ravn Rasmussen August 2004 Abstract In order to make chess programs faster and thus stronger, the two approaches of parallelizing the search and of using clever data structures have been suc- cessful in the past. In this project it is examined how the use of a specific data structure called a bitboard affects the performance of parallel search. For this, a realistic bitboard chess program with important modern enhance- ments is implemented, and several experiments are done to evaluate the performance of the implementation. A maximum speedup of 9.2 on 22 pro- cessors is achieved in one experiment and a maximum speedup of 9.4 on 12 processors is achieved in another experiment. These results indicate that bitboards are a realistic choice of data structure in a parallel chess program, although the considerable difference in the two results suggests that more research could be done to clarify what factors affect such an implementation, and how.

Judicial Recourse for Victims of Gaming Fraud
SMITH FORMATTED 5.22.17.DOCX (DO NOT DELETE) 5/30/17 2:23 PM CHEATER’S JUSTICE: JUDICIAL RECOURSE FOR VICTIMS OF GAMING FRAUD Jordan T. Smith* I. INTRODUCTION Legends of extrajudicial “cheater’s justice” dealt upon gaming con-artists and swindlers have deep historical roots. In the Old West, a card shark may have been shot on sight.1 Later, when the mob (allegedly) ran Las Vegas, a hustler might have been given the choice of “hav[ing] the money and the hammer or [walking] out of here,” but not both.2 Gradually, as gambling became more socially acceptable and government regulation of it increased, disputants transitioned from wielding brutish self-help remedies to pursuing legal retribution.3 Today, courts largely accept that a party cheated in a gambling game can recover any losses in a civil action without necessarily being limited to administrative remedies through a state’s gaming regulators.4 * Mr. Smith is an attorney in Nevada.

Grimes, 64 P. 101, 103 (Cal. 1901) (“The deceased may have treated the appellant unfairly and unjustly in the matter of the game of cards, but that treatment gave appellant no legal excuse or justification for taking his life.”); see also State v. Vansant, 80 Mo. 67, 73–74, 1883 WL 9952, *5 (1883); Johnson v. State, 10 S.W. 235, 236 (Tex. App. 1888); State v. Shadwell, 57 P. 281 (Mont. 1899). -

Feel free to save, print, or distribute this PDF as needed. Section 1: Background Information History ● Chess is widely assumed to have originated in India around the seventh century. ● Until the mid-1400s in Europe, chess was known as shatranj, which had different rules than modern chess. ● Some well-known authors and chess players from that time period are Greco, Lucena, and Ruy Lopez. ● The Romantic Era lasted from the late 18th century until the middle of the 19th century, and was characterized by sacrifices and aggressive play. ● Chess has widely been considered a sport since the late 1800s, when the World Chess Championship was organized for the first time. Other ● Chess is considered a game of planning and strategy because it is a game with no hidden information, where you and your opponent have the same pieces, so there is no luck. ● Studying chess seriously can bring you many benefits, but simply playing it won’t make you smarter. Section 2: Rules of the Game Setting Up the Board ● There are sixty-four squares on the board, and thirty-two pieces (sixteen per player). ● Each player’s pieces are made up of eight pawns, two knights, two bishops, two rooks, a queen, and a king. ● There are two players, Black and White. White moves first. ● If you’re using a physical board, rotate the board until there is a light square on the bottom right for each player. -
