Re: Othello Is Solved?

Correct title: an unknown author from an unknown startup claims in an arXiv preprint (listed somehow in the cs.AI archive) that Othello has been solved. The paper is 13 pages long. I wish that the superconductor debacle (and many others) had taught people critical thinking and skepticism. And yet this is the #1 post on HN right now.

Boo. The paper is cautiously written, addresses a very tractable and well-defined problem, confirms what experts expected, and is straightforward to implement (the source code is on Github). And yet this posturing is the #1 comment on this thread right now.

Great, then let's name it "Othello claimed to be solved", then pound it with peer reviews and reproductions for a bit, then we can phrase it as "Othello is solved".

They are moot because the solution is known. When a human makes a mistake the intrigue is discovering the fix to become better. In solo copetition solved games are highly fascinating because the person is racing the TAS or the solved route. In human versus human games, we can simply look up what the human did wrong. There is no cognitive challenge in answer lookup. Its just oh, he sucks he missed the move. Since its…

In bowling and golf the mistake is athletic. You moved your body wrong, also there are variables such as the wind and humidity of the air in golf, and a in bowling the ball and other micro variables effect play. It's possible to improve physical condition with training, but there is no "perfect". In a fully abstracted competitive game where all variables are eliminated except for mental choices, it becomes about memorization of the solutions if the game is solved.

Does this paper render the championship moot? Is any software based on the paper entered? Is Othello like checkers, where there were mostly draws in high level games?

I don't understand this comment. Computers are not allowed to play in the championship.

I confess to being dumb and not understanding it's a human championship. My bad!

Foot races are also solved - these losers should just get a car!

Cars are not allowed in the rules of the game "foot race", therefore your solution is not valid and therefore your argument has no evidence to support your claim.

You really wouldn't want to have a post sit on top of Hacker News for an hour and nothing comes of it. Think of how much we could have gotten done on this messageboard otherwise!

Boy are you gonna feel foolish when the #2 post on HN is “Cancer almost cured”, and you realize how dangerous a diversion this was…

It's not obvious to me that othello is much more complicated than checkers. Admittedly, I haven't played since I was a kid and I don't completely remember what the rules are.

So you don't really know much about the computational complexity of the game and you're saying it's trivial. How hard a game is to "solve" at least using traditional algorithmic techniques is related to its search space. That is a combination of the length of the game and the number of possible moves in each position (ply and branching factor). Chess has more possible positions than exist atoms in the universe by som…

The person you're responding to wasn't the one that said it was "trivia" (much less trivial).

I don't think anyone was saying it's easy, just that they didn't think it was very useful to know.

This is cool. I solved a simpler game about 15 years ago that my brother and I used to play: an African game with about 10 pits on each side of the board that hold stones. I coded up an alpha-beta engine for it, and discovered crazy always win strategies to match how my brother and I played. Suddenly I would win all the games, and then he never wanted to play again. This was a classic match up of a computer scientist…

Othello is a great game to demonstrate how powerful some basic heuristics can be. There are certain squares that you should avoid placing pebble on as the game develops - equally there are squares that you should definitely try and place a pebble on if you can. Implementing these rules can give you a fairly decent opponent and it's interesting to see how quickly people will ascribe "intelligence" to something that is…

Implementing these rules can give you a fairly decent opponent and it's interesting to see how quickly people will ascribe "intelligence" to something that is very simple.

Who is actually "ascribing intelligence" to this? Othello has been on $10 LCD games that take double AA batteries.

There was absolutely nothing wrong with the superconductor “debacle”. What you're preaching is not skepticism, but cynicism.

Given the myriad posts and articles about "huge breakthrough", "industry changing" and so on, scepticism in that case would translate to way more cynicism.
