1952 - OXO

Facebook Twitter

OXO (Noughts and Crosses) est un jeu vidéo de tic-tac-toe conçu en 1952 par le Britannique Alexander S. Douglas et fonctionnant sur l'EDSAC.

Douglas programme le jeu dans le cadre de sa thèse sur les interactions homme-machine pour obtenir son philosophiæ doctor à l'université de Cambridge. OXO (jeu vidéo) Un article de Wikipédia, l'encyclopédie libre.

Alors que Douglas termine le développement d’OXO, Christopher Strachey parvient en juillet 1952 à faire fonctionner sur un Ferranti Mark I un programme de dames, écrit en 1951, qui affiche sur un écran cathodique le déroulement de la partie. Ces deux jeux sont les premiers à proposer un affichage visuel sur un écran électronique, l’antériorité de cette innovation étant généralement attribuée à OXO. Ce dernier est donc considéré comme le premier jeu vidéo de l'histoire par la plupart des historiens du domaine, bien que certains observateurs estiment qu'il est en réalité difficile de déterminer lequel des deux est le premier à être fonctionnel.

When we say the word game in the context of AI we usually don’t mean it in the sense of entertainment games, instead we refer to a more general definition of a game: A game is a multi-agent environment in which agents compete and/or cooperate on some specific task(s) while meeting some specific criteria.

An agent is referred to as a player. With this general definition we could see that a situation, like driving your car to a specific place, is a game. In such a situation, you (as a player) exist in an environment along with other drivers (other players) and you cooperate with some drivers to avoid crashes and reach your destination and compete with other drivers to reach there fast. We can easily see that entertainment games also fall under the general definition of games. Solve Tic Tac Toe with the MiniMax algorithm. Introduction After learning the MiniMax algorithm, I decided to practice it on Tic Tac Toe.

Solve Tic Tac Toe with the MiniMax algorithm

The algorithm is simple to implement. However, it took me much more time than I expected. So, I would like to share what I have learned here. MiniMax algorithm with alpha beta pruning The shortest description of MiniMax that I can find is from Wikipedia. Hide Copy Code The description on Wikipedia is very short and elegant, but there are some things to watch out: First, we cannot use int.MinValue and int.MaxValue as -/+infinity. Second, the terminal nodes include nodes with no successors, and game-over nodes (winner already decided). Finally, the description on Wikipeida seems to indicate that the node type (min/max) doesn't matter. The second version takes a few more minutes to type.

Heuristic score in Tic Tac Toe The Minimax algorithm can be applied to many games. For each row, if there are both X and O, then the score for the row is 0. Tic Tac Toe: Understanding The Minimax Algorithm. Note!

This article is has also been translated to Japanese and Portuguese. I really appreciate the readers that reached out to me and translated this article. I recently built an unbeatable game of tic tac toe. It was a fun and very humbling project that taught me a ton. If you want to get totally schooled, give the tic tac toe game a shot here. In order to make the game unbeatable, it was necessary to create an algorithm that could calculate all the possible moves available for the computer player and use some metric to determine the best possible move.

It took a little while to really fundamentally understand the algorithm and implement it in my game. Tic-tac-toe AI - Java Game Programming Case Study. 1.

Playing Against Computer with AI (Advanced) Click the image to run the demo for the various AI strategies (under the "Options" menu): Tic-tac-toe seems dumb, but it actually requires you to lookahead one opponent's move to ensure that you will not loss. That is, you need to consider your opponent's move after your next move. For example, suppose that the computer uses 'O'. 1.1 Implementing the AI Player To test the various AI strategies, an abstract superclass called AIPlayer is defined, which takes the Board as an argument in its constructor (because you need the board position to compute the next move). 1.2 Simplest Strategy – Heuristic Preferences via Table Lookup The simplest computer strategy is to place the seed on the first empty cell in this order: the center, one of the four corners, one of the four sides. For example, Algorithme oxo? - Programmation. Oui après tu as différentes possibilité pour coder une "intelligence artificielle" tu peux utiliser un système de priorité: ton ordi joue à chaque coup le coup correspondant de priorité la plus élevés dans ta stratégie (ex: prio 1 "coup gagnant", prio 2 "contrer coup gagnant adversaire", prio 3 "coup gagnant au prochain coup" etc... souvent les priorité sont symétrique mais c'est à toi de les définir, et l'ordinateur doit toujours jouer un coup quelque soit la position, donc il doit y avoir un coup "standard".)
