  3. Evaluation function - Wikipedia

    en.wikipedia.org/wiki/Evaluation_function

    [4] [5] In addition, with the advent of programs such as MuZero, computer programs also use evaluation functions to play video games, such as those from the Atari 2600. [6] Some games like tic-tac-toe are strongly solved, and do not require search or evaluation because a discrete solution tree is available.

  4. Endgame tablebase - Wikipedia

    en.wikipedia.org/wiki/Endgame_tablebase

    Use of an endgame tablebase might be permitted in a live game even if engine use is forbidden. Players have also used tablebases to analyze endgames from over-the-board play after the game is over. A six-piece tablebase (KQQKQQ) was used to analyze the endgame that occurred in the correspondence game Kasparov versus The World. [46]

    The rating of best Go-playing programs on the KGS server since 2007. Since 2006, all the best programs use Monte Carlo tree search. [14]In 2006, inspired by its predecessors, [15] Rémi Coulom described the application of the Monte Carlo method to game-tree search and coined the name Monte Carlo tree search, [16] L. Kocsis and Cs.

  6. Negamax - Wikipedia

    en.wikipedia.org/wiki/Negamax

    The person performing the game tree search is considered to be the one that has to move first from the current state of the game (player in this case) NegaMax operates on the same game trees as those used with the minimax search algorithm. Each node and root node in the tree are game states (such as game board configuration) of a two player game.

  7. Alpha–beta pruning - Wikipedia

    en.wikipedia.org/wiki/Alpha–beta_pruning

    Alpha–beta pruning is a search algorithm that seeks to decrease the number of nodes that are evaluated by the minimax algorithm in its search tree.It is an adversarial search algorithm used commonly for machine playing of two-player combinatorial games (Tic-tac-toe, Chess, Connect 4, etc.).

  8. Bertie the Brain - Wikipedia

    Bertie the Brain was a video game version of tic-tac-toe, built by Dr. Josef Kates for the 1950 Canadian National Exhibition. [1] Kates had previously worked at Rogers Majestic designing and building radar tubes during World War II, then after the war pursued graduate studies in the computing center at the University of Toronto while continuing to work at Rogers Majestic.

  9. Quantum tic-tac-toe - Wikipedia

    en.wikipedia.org/wiki/Quantum_tic-tac-toe

    Quantum tic-tac-toe is a "quantum generalization" of tic-tac-toe in which the players' moves are "superpositions" of plays in the classical game. The game was invented by Allan Goff of Novatia Labs , who describes it as "a way of introducing quantum physics without mathematics", and offering "a conceptual foundation for understanding the ...
