WebIn game theoryterms, an expectiminimax tree is the game tree of an extensive-form gameof perfect, but incomplete information. In the traditional minimaxmethod, the levels of the tree alternate from max to min until the depth limit of the tree has been reached. In an expectiminimax tree, the "chance" nodes are interleaved with the max and min nodes. WebOct 25, 2024 · The minimax algorithm is designed for finding the optimal move for MAX, the player at the root node. The search tree is created by recursively expanding all nodes from the root in a depth-first manner until either the end of the game or the maximum search depth is reached. Let us explore this algorithm in detail.
