AI Strategies, the iPhone, and Go

iGo on iPhone

We’ve been playing Go during lunch at work lately. Mark Lentczner, one of our engineering directors, is a long-time Go enthusiast, runs the Go center in Second Life, and has been teaching us.

So when Jens mentioned iGo for the iPhone, I bought a copy, and stayed up late one night this week working on beating the AI on a 7 x 7 board without a handicap.

I showed this the next day to Mark, who reminded me of an earlier conversation about the trouble with playing Go against an AI. Most modern Go AIs use monte carlo methods to determine their play, and the resulting style of play is nothing like a human opponent.

Instead, he suggested getting Smartgo touch. It’s a collection of a couple of thousand Go ‘problems’ to work through to improve your game.

You don’t need an AI to play Go if you’re alone, get on the KGS Go Server, and you’ll find an opponent.

    As I suggested a few months ago in http://jtauber.com/blog/2008/07/07/turing_chess/ I’m surprised there hasn’t been more effort put in to making Chess or Go programs that attempt to pass a Turing test rather than simply beat humans.
