Results............................................................................................ 128 vi Abstract Computer chess has played a crucial role in Artificial Intelligence research since the creation of the modem computer. It has gained this prominent position due to the large domain that it encompasses, including psychology, philosophy and computer science. The new and innovative techniques initially created for computer chess have often been successfully transferred to other divergent research areas such as theorem provers and economic models. The progress achieved by computers in the game of chess has been illustrated by Deep Blue’s famous victory over Garry Kasparov in 1997. However, further improvements are required if more complex problems are to be solved. In 1999 the Kasparov versus the World match took place over the Internet. The match allowed chess players from around the world to collaborate in a single game of chess against the then world champion, Garry Kasparov. The game was closely fought with Kasparov coming out on top. One of the most surprising aspects of the contest was the high quality of play achieved by the World team. The World team consisted of players with varying skill and style of play, despite this they achieved a level of play that was considered better than any of its individual members. The purpose of this research is to investigate if collaboration by different players can be successfully transferred to the domain of computer chess. Chapter 1 Introduction 1.1 Importance of Chess in Artificial Intelligence Research Artificial Intelligence, simply referred to as AI, is the area of research concerned with the creation of computational entities that exhibit intelligent behaviour. These entities would have the ability to perform difficult or unwanted tasks on our behalf. Since the inception of AI, fantastical ideas of the progress of AI have been made, such as the character of HAL in the film "2001: A Space Odyssey”. Unfortunately science fiction left reality far behind in the creation of intelligent entities. Progress in AI has been slow

Flower Design Mammoth Ivory Set which I am taking offers on In 1835, Nathaniel Cooke designed new chessmen dedicated to one of the strongest chess players of the day: Howard Staunton. Today, Oleg Raikis, a famous Russian sculptor, continues this tradition. "Chess of the 21st Century", inspired by the balance and simplicity of the Staunton design, is dedicated to today's strongest chess players: Former World Champion Garry Kasparov, World Champion Vladimir Kramnik, and Women's World Champion Xie Jun.

    Archbishop to Dedicate New St. John’s on Dec. 2 Member of Audit Bureau of Circulations Third Major Church Dedication in Year Contents Copyright by the Catholic Press Society, Inc., 1953—Permission to Reproduce, Except on Articles Otherwise Marked, Given After 12 M. Friday' Following Issue When Archbishop Urban J. Vehr dedicates the new St. John the Evangelist’s Church Wednes­ day, Dec. 2, it will be the third major church on principal Denver thoroughfares that' he has blessed in a little more than a year. DENVER CATHaiC The ceremonies at St. John’s will begin at 10:30, and will be followed immediately by a Sol­ emn Mass to be offered in the presence of the Arch­ bishop by the ^t. Eev. Monsignor John P. Moran, pastor. REGISTER The two other major Denver churches dedi­ cated in the past year are St. Catherine of Siena’s, fronting on North Federal Boule­ vard at 42nd Avenue,, dedicated on Thanksgiving day, Nov. 27, 1952; and St. Vincent de Paul’s, facing S. University Boulevard at E. Arizona Avenue, which was dedicated Feb. 11, 1953. The new St. John's faces beautiful East Seventh Avenue Parkway at Eliza­ beth Street. The three new edifices give Denver an array of magnificent Catholic churches of which it may well be proud, and which are un­ excelled by any city of comparable size in the nation. John K. Monroe of Denver was architect for the new building, which was erected by the F. J. New St. John’s Is Handsome Addition on Seventh Avenue Parkway Kirchhof Construction Co.

  • Saul Sorrin: Oral History Transcript
    Saul Sorrin: Oral History Transcript www.wisconsinhistory.org/HolocaustSurvivors/Sorrin.asp Name: Saul Sorrin (1919–1995) Birth Place: New York City Arrived in Wisconsin: 1962, Milwaukee Project Name: Oral Histories: Wisconsin Survivors Saul Sorrin of the Holocaust Biography: Saul Sorrin was an American witness to the Holocaust. He aided survivors at displaced persons camps in Germany as an administrator from 1945 to 1950. Saul was born on July 6, 1919, in New York City, where he attended the City College of New York. In 1940, he applied for a position with the United Nations Relief and Rehabilitation Administration (UNRRA). At the end of 1945, Saul was sent to Neu Freimann Siedlung, a displaced persons camp near Munich, Germany, to help Holocaust survivors. In 1946, he hosted General Dwight D. Eisenhower on an inspection tour of Neu Freimann. At Eisenhower's recommendation, Saul was appointed permanent area director at the Wolf- Ratshausen camp in Bad Kissingen. He served there until March 1950. Saul became deeply committed to the survivors he was helping. He ignored many illegal actions, violated countless rules and regulations, and helped refugees alter their documents to sidestep a variety of restrictions. Saul also aided those who wanted to immigrate illegally to countries with quotas. He even permitted refugees to hold secret military training for the newly formed state of Israel. Saul helped set up cultural institutions in the displaced persons camps he supervised. He began schools and synagogues and organized sporting events and entertainment. He was also able to bring in famous performers. After the war, Saul returned to the U.S.
