About:
This implementation of tictactoe can have an NxN sized board, where N is an odd number >= 3. What makes this implementation different from others is that it does not use lookahead, and still never loses. It is more of an experiment than anything else.

Release focus: Minor bugfixes

Changes:
Another losing case was fixed. The program is stable enough that any losses can be fixed by only manipulating different scores.

[»] can't loose, but doesn't win when it can...
by Pinion - Dec 15th 2001 20:09:17

I know, I'm bored, but I usually check all TicTacToe implementation using standard strategies. This one failed one of them. It seems that the software wants to draw, not to win! which I find a bit weird (but that just me :).

I'm reffering to the classic mistake: (computer is X)

- 0 -
- X -
- - -

Obviously, I lost, but the computer responded with:

X 0 -
- X -
- - -

Which means that I can draw the game again. Trying to put the 0 in different places but with the same strategy resulted the same (0 in 1/2, 2/1, 3/2, 2,3).

As I said, I was bored...

Well, the computer's move was correct, it's its next move that is wrong:

X O X
_ X _
_ _ O


when it should have put the X at 3,1, it puts it at 1,3.

I'm still tweaking the scores, and every post like this helps me make it better, so thank you. I'll add this to my test cases.

lol. Ya, that was expected. I guess I should have mentioned it in the readme file, although it is mentioned in the project record on freshmeat: an NxN sized board, where N is an odd number >= 3 So, I concede. My program can lose for boards of size 1. It will win if it plays first though.

I did see that in the freshmeat listing. Its just having recently seen the episode i thought it would be amusing.

The only other amusing fact is if the board size is 0 the computer wins.

Interesting peice of software... Maybe you could get the computer to play itself?

Darn. Must've missed that one.

Either way, with board size 0 or 1, run tictactoe X, to invert the winner.

The ultimate goal would be to get it to play itself, but first I'd have to remove the explicit win and dont_lose rules. For now, run it on two terminals, one with tictactoe O, and the other tictactoe X, pass moves from one to the other manually (If Tomorrow Comes ;)

maru batsu.eu uses this logic for tic tac toe but it is more developed and works on larger boards. Not sure if it should be called tictactoe though, probably maru batsu as the name of the domain suggests it.

Nice to know. What do you mean by larger boards though? My version works with boards of infinite length (assuming you have the memory) as long as it's a positive odd integer - 0 being the only even number allowed.
