In combinatorial game theory, a fuzzy game is a game which is ''incomparable'' with the zero game: it is not greater than 0, which would be a win for Left; nor less than 0 which would be a win for Right; nor equal to 0 which would be a win for the second player to move. It is therefore a first-player win. ==Classification of games== In combinatorial game theory, there are four types of game. If we denote players as Left and Right, and G be a game with some value, we have the following types of game: 1. Left win: G > 0 :No matter which player goes first, Left wins. 2. Right win: G < 0 :No matter which player goes first, Right wins. 3. Second player win: G = 0 :The first player (Left or Right) has no moves, and thus loses. 4. First player win: G ║ 0 (G is fuzzy with 0) :The first player (Left or Right) wins. Using standard Dedekind-section game notation, , where L is the list of undominated moves for Left and R is the list of undominated moves for Right, a fuzzy game is a game where all moves in L are strictly non-negative, and all moves in R are strictly non-positive. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Fuzzy game」の詳細全文を読む スポンサード リンク
