and there you have it...

comments?

Damnedest kind of VB I ever saw....

Damnedest kind of VB I ever saw....

Maybe beacuse it is C++.

[Arbiter]

Really?

Oh wow! I hadn't realised!!

[rjlohan]

Hey, has anyone developed an 'A.I' for tic-tac-toe.

I know it's simple, but most(ALL) TTT games I see work the computer move by running it through every board combo and making the appropriate move.

I just made one where the computer is initially VERY easy to beat, but after many games, it will learn which moves lead it to win, and which lead it to lose, and thus I am hoping it will 'learn' to make its own decisions based on its game history.

If anyone is interested, I wouldn't mind some testers...

[plenderj]

Yeah go on post the code.

[rjlohan]

Here you go.

I am aware of some bugs, but haven't had a chance to sort them out...

I just added another section to the computer's AI which I am not sure is working correctly, but we'll see...

Be sure to set the difficulty to 'Hard' when you run the program, or the computer will make completely random moves.

If you feel like fiddling with the DB, the password is 'ttt'.

Cheers.

[plenderj]

Hmmm crashed with an AccessDB error when I selected Hard and then took my move

Probably because you'd hardcoded the path :

Const strConnection = "Provider=MSDASQL.1;Persist Security Info=False;Extended Properties='DBQ=C:\VB Projects\TTT AI\ttt.mdb;DefaultDir=C:\VB Projects\TTT AI;Driver={Microsoft Access Driver (*.mdb)};DriverId=25;FIL=MS Access;FILEDSN=C:\VB Projects\TTT AI\ttt.mdb.dsn;MaxBufferSize=2048;MaxScanRows=8;PageTimeout=5;SafeTransactions=0;Threads=3;PWD=ttt;UserCommitSync=no;';Initial Catalog=C:\VB Projects\TTT AI\ttt"

Would I be right i saying that you're basically keeping account of how successful the computer player was given certain board configurations ?

[rjlohan]

Whoops... I just C&P the connection string...
