alpha-beta pruningThe minimax algorithm, also called the negamax algorithm, remains today the most widely used search technique for two-player perfect-information games. However, minimaxing has been shown to be

This project was a large learning experience for me: it was one of my first programming projects. I initially created a simple AI for Connect Four back in 2010, and then improved it when I learned about minimax and alpha-beta pruning in 2012....
alpha-beta pruning is a method for cutting off whole branches of thegame tree so that they don’thave to be evaluated with minimax. In essence, the algorithm maintains twoextra values during the minimax recursion: alpha and beta. Alpha is the minimumvalue for Max (biggest loss for...
Let's see how we can implement alpha-beta pruning in the Minmax algorithm.First, we will add an alpha and a beta argument to the argument list of Minmax:def min_max(state, depth, is_maximizing, alpha, beta):if depth == 0 or is_end_state(state):...
The Minmax algorithm works great, especially with alpha-beta pruning. The only problem is that we have if and else branches in the algorithm that essentially negates each other. As we know, in computer science, there is DRY code and WET code. DRY stands for Don't Repeat Yourself. WET st...
In this context, it is important to have estimates that are close to the real costs, because better estimates facilitate more extensive pruning of the search tree. In general, lower bounds are also useful for assessing the quality of solutions obtained from incomplete algorithms. This is ...
Alpha-beta pruning: safely cut any branch that is provably dominated by another variation. Additional cuts are achieved using aspiration windows and principal variation search. Null move pruning: assumes a pass move should be worse than any variation, in positions that are unlikely to be in zu...
This paper proposes an imperfect information multi-player Military Chess system basing on UCT algorithm which also adopts Monte- Carlo sampling and some other classic game algorithms (alpha-beta pruning, TD (λ) Learning and history heuristic). The realization and modification of UCT for Military ...
