A striking advance in mathematical game theory earned top honors for the team of James Pinkerton 1d (l), and Rafael Setra (r) in the recent Region Five Finals of the 2010-11 Siemens Competition in Math, Science & Technology
, a premier science research competition for high school students. Pinkerton, an avid go player, and Setra are seniors at Montgomery Blair High School in Silver Spring, Maryland. Their win in the team category has scored them a $6,000 scholarship for their mathematics project, The Duplicator-Spoiler Game for an Ordinal Number of Turns. Their math research might be analogized to mirror go–the players, a spoiler and a duplicator alternate turns, choosing elements from two sets until the duplicator is unable to mirror the spoiler’s move.
In the math, the number of turns for the spoiler to win tells you about the complexity of statements in mathematical logic needed to differentiate the sets. Traditionally the games have a finite number of turns and their research extended the games to arbitrary lengths over various infinite structures. “This team has made a striking extension of a game-theoretic interpretation of descriptive logic that dates back to the 1960s. Using it, they can distinguish between mathematical structures not separable by simple queries,” said competition judge Haynes Miller, Professor of Mathematics at MIT. “Their work has potential applications to resource allocation in designing search algorithms. What impressed me about these students was their clarity of thought. It’s a very confusing subject to work in and they found their way through it to a new frontier.”
Pinkerton is president of the Chess Club and a member of the National Honors Society and French Honors Society. Fluent in French, he single sculls on the Potomac and plays chess and go competitively. Pinkerton teaches chess as a volunteer in several programs in his county and in inner-city Washington, DC. He also teaches mathematics to underclassmen. He credits his father (E-J staff photographer John Pinkerton) who taught him “fun mathematics, not the dreary algebra of secondary school,” with nurturing his love for the subject. Pinkerton would like to study mathematics in college and to become a university professor. Setra was born in Sao Paulo, Brazil, and moved to the US when he was eight years old. He speaks Portuguese and Spanish and is part of Operation Fly, National Honors Society and the Martial Arts Club. A volunteer at Viers Mill Elementary School, Setra plays Starcraft 2, non-competitive football and has just learned how to play go from Pinkerton. He would like to study mathematics, engineering and computer science and to become a college professor.
“Each year, the Siemens Foundation invites America’s high school students to make their mark in the world of science,” said Jeniffer Harper-Taylor, President of the Siemens Foundation. “We commend these students on rising to the challenge and pushing the envelope of scientific thought.” The students presented their research to a panel of judges from Massachusetts Institute of Technology (MIT), host of the Region Five Finals, on November 6th. Pinkerton and Setra will also be invited to compete at the National Finals in Washington, DC, December 3–6, 2010, where the winners of six regional competitions will vie for the $100,000 Grand Prize and national acclaim for extraordinary scientific achievement at the high school level.

A total of 19 players ranging from 17 kyu to 2 dan attended a pair of one-day workshops recently with Tadashi Sasaki 8P in San Francisco and Menlo Park, CA. This was Sasaki’s first visit to Northern California in over 20 years, and he was pleased to finally get to ride the San Francisco cable cars. His last visit was shortly after the 1989 earthquake and the cable cars were not running. Each student got to play a teaching game with Sasaski, including review and analysis. The small class size each day allowed students to ask lots of questions and get individual attention. Click here for more photos. Asked what he enjoys doing when he isn’t playing go, Sasaski laughed and said “Teach go, of course.”

Tadashi Sasaki 8P will give two separate teaching events this week in Los Angeles as part of his West Coast tour. Sasaki, a professional go player from the Nihon Kiin, was a pupil of the late Eio Sakata. Both events will feature simultaneous 3-on-1 games with Sasaki, followed by a game analysis. Players not involved in a teaching game are free to watch, or to play a game with others which will be analyzed later. “Those who have attended Sasaski’s lectures at the annual U.S. Go Congress or at his previous workshops in Washington and Los Angeles will testify to his straightforward answers to questions and his gentle sense of humor,” says organizer Richard Dolen. “His comments are useful for all levels of go strength.” Come early for the best chance to play Sasaki. The events are organized by Andy Okun, Tom Oki of the New Gardena Hotel, Joe Cepiel of the Santa Monica Go Club and others. For more info, contact Dolen at email@example.com
The first LA Sasaki event begins at 7p this Tuesday, November 9th at the Santa Monica Go Club at the Unurban Coffee House (3301 Pico Blvd, Santa Monica, CA); there’s no charge for club members, and $10 for others (there may be a nominal surcharge for playing Sasaki).
The second event begins at 7p Wednesday, November 10th, at the basement level of the New Gardena Hotel (1641West Redondo Beach Blvd # 1, Gardena, CA); the charge for attendance is $20 per person and again, there may or may not be a nominal surcharge for playing a teaching game with Sasaki.

The competition was fierce for large orange vegetables as a field of 43 competed at the NOVA Pumpkin Classic in Arlington, Virginia on October 30. Justin Teng 4d (r) won the dan division with a 4-1 record, while the 2009 winner, Jing Guo 7d, came in second. First places in the kyu divisions included an undefeated Kelsey Dyer 2k, David Reed 6k (also undefeated), Joey Phoon 7k, Kenny Huynh 10k, Joseph Lee 15k (undefeated), Tristan Tran 17k (undefeated), and Tariq Khan 26k (undefeated). Second places in the kyu divisions included Kevin Chin 3k, Robert Ehrlich 5k, Daniel Monahan 8k, Julian Erville 11k, Jake Altizer 14k, and Jordan Howar 17k. The popular Team Tourney was back and Team Phoooon (below) decimated the competition by winning 15 out of their 16 games. NOVA organizer Gary Smith was “delighted that we signed up 10 new AGA youth members at the event.” Tournament Director Zhiyuan ‘Edward’ Zhang managed to schedule five rounds for players interested, adding an option for fast players to enjoy more go and have more fun. The final score is calculated by winning percentage, with is uniform for traditional four-round players (i.e. 4-1 record is better than 3-1; 3-1 better than 3-2). This new approach not only reduced wait time for some players, but also encouraged a competitive spirit of going the extra mile by playing a fifth game to be the clear winner instead of settling on a tie-breaker.
