1. ## Tic-Tac-Toe help needed

I am at the moment writing functions that will simulate an intelligent computer AI. I can get the 2 player function to work, but I cannot even think of a way to do a computer algorithm besides getting every single possible move that can happen and using them in huge if statements. Help plz.

2. www.generation5.org
There's some good AI info on that site... especially for the type of problem you're using it for.

3. AI for tictactoe is just a simple case of...

If win_poss then win
if loss_poss then stop_loss( sometimes its possible to lose on more than 1 square. You can only stop one).
else take random untaken square.

4. Or you could go through every possibility, and see which move gives you the best chance of winning.

5. As a matter of fact, if the computer moves second, it can always force a draw. If it moves first, then it can play in the center, which is a winning strategy if the other player doesn't play on a corner.

6. the best algorithm (but hard) to implement for your tictactoe ai is the minimax tree.

7. my friend and i were bored in algebra class one day and decided to play tic tac toe, lol. anyways, there are SO many strategies to win a tic tac toe game.
examples:
1: take one corner
if the middle is not taken take the opposite corner diagonally, if that is taken, take any corner
take a corner that will possibly seal the win
2: take a center square on the border
take a corner on the other side of board
take another corner
3: take center
take a center on the border
take any corner

just write strategies that could possibly work. then base your ai reactions on what strategies could be used.
