Negamax オセロ

WebIn order for negaMax to work, your Static Evaluation function must return a score relative to the side to being evaluated, e.g. the simplest score evaluation could be: score = materialWeight * (numWhitePieces - numBlackPieces) * who2move where who2move = 1 for white, and who2move = -1 for black.

c# - How to use negamax algorithm - Stack Overflow

WebThe chess engine uses a simple tree search using NegaMax (a variant of MiniMax) with alpha-beta pruning implemented. NegaMax relies on the mathematical maxim to shorten the MiniMax algorithm to roughly half the lines of MiniMax while maintaining identical performance: function negamax (node, depth, α, β, player): if depth = 0: return player ... Webこのように書き換えたアルゴリズムを「NegaMax」と呼ぶ。 MinMaxとNegaMaxは全く等価な方法である。また、「αβ法」も「NegaMax」形式に書き換えられる。ここでは、そのように書き換えたαβ法のプログラムを「Negaαβ」と呼ぶことにする。 touch screen calendar kitchen https://yangconsultant.com

The short answer to your question is that negamax returns the score for a particular position, so what you would do is play every move at the first ply, call negamax for each resulting position to evaluate it, and then pick the move with the best score as the outcome.
