Depth that Minimax searches to

Random move

In our research, we set Random move = 3. Then, Minimax chooses randomly from the first two best columns at 3th, 6th, 9th, ... move.

The number of features

The 4 features can be included or excluded in the heuristic function.

Heuristic function

In our research, we will let two different heuristic functions fight against each other to see how the indexes change.
