And it was there that he began to hear about Marion Tinsley, the great. Security should have been concerned.” And they were.
A group of scientists at Canada's Alberta University were the brains behind Chinook a computer program designed to beat human competitors at checkers.
“From the end of the Tinsley saga in ’94–’95 until 2007, I worked obsessively on building a perfect checkers program,” Schaeffer told me. With Tinsley gone, the only way to prove that Chinook could have beaten the man was to beat the game itself. As the software developed through the years, it retained two core components. From 1950 to 1990, Tinsley had been the world champion of checkers whenever he wanted to be. In 1992, Chinook played world champion Marion Tinsley, who had remained nearly undefeated for more than four decades. That was certainly the idea back in the mid-1950s, when an IBM research scientist named Arthur Samuel began to experiment with getting a checkers-playing program to run on an IBM 704. His lunch was “a jar of milk, half an apple, and a peanut butter sandwich.”, His relationship with the racial dynamics of the South is also fascinating. The results would be published July 19, 2007, in Science with the headline: Checkers Is Solved.
It was something close to godly, though. His opponent was Chinook, a checkers-playing program programmed by Jonathan Schaeffer, a round, frizzy-haired professor from the University of Alberta, who operated the machine. If Chinook's human opponent doesn't make any mistakes—in other words, if the game is … Chinook is a computer program that plays checkers (also known as draughts). Tinsley says, “I’m ready to go,” and Schaeffer acts befuddled. At first they called it The Beast, but eventually they named it Chinook after the warm winds that sometimes blow through Alberta. contest was only the latest in a long-running battle.

But they knew that they couldn’t calculate every possible position. “I haven’t seen a checker marriage that worked out,” he told a reporter. And Sutton also happens to be one of Schaeffer’s colleagues at the University of Alberta, where Google’s DeepMind AI shop recently announced it will set up its first international research office.
We want to hear what you think about this article.
And after Chinook’s 1990 performance, Tinsley called up Jonathan Schaeffer and asked if he might like to play a few friendly matches. https://en.wikipedia.org/w/index.php?title=Chinook_(computer_program)&oldid=974711515, Official website different in Wikidata and Wikipedia, Creative Commons Attribution-ShareAlike License, 1997 - Jonathan Schaeffer writes a book about Chinook called. No contemporary accounts ask any of the black students what they made of their checkers-champion professor, but a colleague was able to describe Tinsley’s role in a local obituary: “At his retirement dinner, literally everybody; young, old, black, white, students, faculty members ... gave testimonies about the impact he had had on their lives.” For a man of his time and upbringing in Kentucky, his path seems almost miraculous. The two men sat in his office and began the matches, Schaeffer moving for Chinook and entering changes in the game into the system. At the highest levels, checkers is a game of mental attrition. He worked on the problem for the next 15 years or so, publishing several important papers on what he called—and what we all would now call—“machine learning.”.
He was an introvert who “felt unloved” by his parents, who he thought doted on his sister. He was a young man programming computers to play an old man’s game. What they have recently shown is that, in any game, they can get to a 10 pieces configuration where Chinook cannot lose. That earned the software the right to challenge Tinsley for the world championship. He seems otherworldly or, at the very least, othertimely. He never married. The sport has been officially conquered by computers, but the wave of artificial intelligence has long moved on to more difficult challenges, leaving the humans to beat up on each other in places like the Honeysuckle Inn and Conference Center in Branson, Missouri. January 18, 2006 - The Chinook team announces that the 09–13 21–17 05–09 opening is proven to be a draw. Jonathan Schaeffer did not begin his career intending to solve checkers. I didn’t take advantage of that and reap the benefits of a warm and deep friendship that I had with him,” he told me. The grave is marked by a simple headstone: Marion F. Tinsley. I wish I would have done things differently, but at the time, when you’re obsessed, you can only see in one direction.”. “I guess it will be part of me until the day I die.”. “Out of the clear blue sky an improvement of a published play will just come to mind, as if the subconscious has been working to come to light,” he told the Chicago Tribune in 1985.
He’d devoted years of his life to creating a program that could beat the best checkers player ever, and just as he was about to realize this dream, Tinsley quit. “Tinsley immediately said, ‘You’re gonna regret that.’” Schaeffer said. This was a narrow kind of intelligence to develop, but it was part of the long arc of the development of artificial intelligence, which is expected to revolutionize the world within this generation. And that would lead Schaeffer to undertake a 13-year computational odyssey to exorcise the man’s ghost. The cup is each calculation. So, if there were six pieces left—and as time went on, seven, then eight—Schaeffer’s software knew every possible combination. This would seem to make checkers a game amenable to computer play. Derek Oldbury, probably the second best player of all time, wrote an encyclopedia of checkers.
