How is a minimax calculated in artificial intelligence?

Take the third row (Maximizer) from the top, for instance. Next, we compare the values from each node with the value of the minimizer, which is +∞. Finally, the maximizer will then again choose the maximum value between node B and node C, which is 4 in this case.

How is minimax algorithm used in game theory?

Minimax algorithm is a recursive algorithm which is used in decision-making and game theory especially in AI game. It provides optimal moves for the player, assuming that the opponent is also playing optimally. For example, considering two opponents: Max and Min playing.

Which is the best algorithm for solving Connect 4?

How to implement negamax reccursive algorithm for Connect 4?

To implement the Negamax reccursive algorithm, we first need to define a class to store a connect four position. We will use a minimal interface allowing us to check if a column is playable, play a column, check if playing a column makes an alignment and get the number of moves played so far.
