  • Tue 5-7pm Robot Chess match at Sheraton Centre Toronto / Can. Open run

    As part of the AAAI 2012 Robotics Fair, I am playing a demonstration chess match against a fully robotic player running Houdini. The Lego-built robot is perhaps the closest ever to a full implementation of The Turk (sans turban), with visual move recognition and manual execution of moves on a standard-size chess set. It has been designed by a team at Canisius College in Buffalo led by Debra T. Burhans, who was also on the Program Committee of the Educational Advances in AI workshop of the conference.

    The match is set for tomorrow (Tue.) 5-7pm at the Sheraton Centre, 123 Queen St. W at University Avenue. We are still unsure about public access to the Robotics Fair, but send me e-mail if you are interested and perhaps I'll know more after returning to Buffalo from NJ tonight. The fair is on page 13 of the conference program (long PDF file); here is a one-page description.

    AAAI is considered the world's leading conference on artificial intelligence. Professor Manuela Veloso of CMU, the President of the AAAI organization, will also be taking part in the Robotics Fair.


    I have done a Single-PV run of the Canadian Open Premier, and have posted it on my site here. The error shown is unscaled ("raw") error, which I call AD not AE for "average difference". This is not the full Multi-PV run which I use to compute Intrinsic Performance Ratings, and which would take about 20 days for 300 games. Hence it does not really judge skill, but gives some indication of accuracy as well as serving as my scientific control for coincidence with computers---GM John Fedorowicz was the most accurate, and IM Stefan Zierk was the only other to hit 60% matching to Rybka 3.

    If any more games are forthcoming, I will run them and update the file. Thanks to all who compiled them---also of the Toronto International and Quebec Open which I will also run.

    We believe it is open-access---it is after all a "Fair". The full team is Michael Lanighan, Jerod Sikorskyj, Debra Burhans, Robert Selkowitz; the three others are students at Canisius College in Buffalo, NY.

      From Dr. Burhans: The robot fair will be held in the foyer area in front of the Grand Ballroom on the lower concourse level -- [which] means anyone can wander in/by -- you won't need a badge to get into that area, totally open to the public. The poster session will also be on that level Tuesday from 5:30-7:30. In addition to robot stuff other exhibits will be in the same area.

        Except for a problem holding on to Knights, the robot performed nearly flawlessly, carrying on a 40-move game at roughly a minute per move. Many of the 30-40 spectators stayed throughout. Global TV did a brief segment for its 16x9 show before we started playing. We will be at it again tomorrow from about 9:45am.

        Here is the game with light annotations---I could have stayed nearly equal with 25.h5!

          Second and last game. My 14...c4?! attacking idea met a powerfully centralizing pawn sac. After 16...cxb3? 17. c4! I think Black may already be lost. Best is 16...Bxb2 17. Rad1 Bg7 18. bxc4 Qa5 shedding stuff but hanging on.

            Do you have any photos of the robot?

              Here's a demo from last year.
              http://www.youtube.com/watch?v=LzVrEsponQU

              Shallow Blue takes a photo of the board and can catch illegal moves. It doesn't look like the Turk but something in a factory. I remember an early computer chess home game that had a moving arm.

                Thanks for the interest. The main difference from last year in San Francisco is that it now does video move recognition. Here are three photos---I've halved the sizes. The first one shows me and the robot---we didn't have a turban, but I brought two books on "The Turk" as props and to show people, one visible at right:



                Here is my view of the robot, before the second game where I had Black.



                And here are the project's faculty sponsors, Debra Burhans and Rob Selkowitz:

                  Here are the "Intrinsic Ratings" given by my model, using an updated equation over the one shown in the paper:

                  KWRvLH: 2561 & 2078--3045 & 1884--3238, 46 moves
                  LHvKWR: 3243 & 3095--3391 & 3036--3450, 45 moves

                  The second column of error bars allows for an extra 40% modeling error besides the intrinsic statistical uncertainty---this is what histograms of actual performances tell me to use, pending further improvements to the model. Note of course that even the narrower range is huge---45 moves is a tiny sample. As always, moves 1--8 and all moves where one side is judged to have more than 3 pawns' advantage are discarded. Anyway, both numbers are higher than I expected, and the larger error bars still give me 95% confidence that Houdini at 6 sec./move (no ponder) on the multi-core hardware played above 3000 strength. This is closer to programmer Jerod Sikorskyj's estimate of 2900 strength than my own estimate of 2700.
