Hi to all
I'm new in Ocaml language. 
I tried to develop a simple program to play at tic tac toe against computer.
I developed several functions:
- a function to insert the coins into the grid,
- functions to check win/lose/pair etc...
The only thing that I cannot do is to implement the main function: the I.A 
algorithm!
I want use the minimax algorithm using recursive function, but I'm not able..
Can anyone help me?
Attached to this email there is what I developed till now

Thank you
