The 24 puzzle is an arithmetical puzzle in which the objective is to find a way to manipulate four integers so that the end result is 24. For example, for the numbers 4, 7, 8, 8, a possible solution is . The problem has been played as a card game in Shanghai since the 1960s, [ 1] using playing cards. It has been known by other names, including ...
Chopsticks (sometimes called Calculator, or just Sticks) [citation needed] is a hand game for two or more players, in which players extend a number of fingers from each hand and transfer those scores by taking turns tapping one hand against another. [ 1][ 2] Chopsticks is an example of a combinatorial game, and is solved in the sense that with ...
2. Chance. None. Nim is a mathematical game of strategy in which two players take turns removing (or "nimming") objects from distinct heaps or piles. On each turn, a player must remove at least one object, and may remove any number of objects provided they all come from the same heap or pile. Depending on the version being played, the goal of ...
Solid. v. t. e. In geometry and trigonometry, a right angle is an angle of exactly 90 degrees or 2 radians [ 1] corresponding to a quarter turn. [ 2] If a ray is placed so that its endpoint is on a line and the adjacent angles are equal, then they are right angles. [ 3] The term is a calque of Latin angulus rectus; here rectus means ...
Order of operations. In mathematicsand computer programming, the order of operationsis a collection of rules that reflect conventions about which operations to perform first in order to evaluate a given mathematical expression. These rules are formalized with a ranking of the operations. The rank of an operation is called its precedence, and an ...
Go. The game of Go is one of the most popular games in the world. As a result of its elegant and simple rules, the game has long been an inspiration for mathematical research. Shen Kuo, an 11th century Chinese scholar, estimated in his Dream Pool Essays that the number of possible board positions is around 10 172.
Minimax (sometimes Minmax, MM[ 1] or saddle point[ 2]) is a decision rule used in artificial intelligence, decision theory, game theory, statistics, and philosophy for minimizing the possible loss for a worst case ( max imum loss) scenario. When dealing with gains, it is referred to as "maximin" – to maximize the minimum gain.
Algebraic notationis the standard method for recording and describing the moves in a game of chess. It is based on a system of coordinatesto uniquely identify each square on the board.[1] It is now almost universally used by books, magazines, newspapers and software, and is the only form of notation recognized by FIDE, the international chess ...
