Tic Tac Toe Artificial Intelligence

In this post I'm gonna include some of the codes I used personally to construct the computer AI.

It is mainly consist of if-else condition and it is not that relieable. If I were given a 2nd chance, I'll write a better AI codes that this one such as using switch/map/binary tree/etc .

If you are a student searching for an AI reference, I strongly recommend you to use your own creativity and understanding and please dont copy mine 100% . Because by copying my codes,
you'll not be able to gain the satisfaction feeling after you have comlpeted the codes.

Oh , one more thing! my AI is only about 70% intelligent I guess . I ensure you that you can't beat my AI if you are the 2nd player . Enjoy!
