In mathematics, "Mex" stands for "minimum excluded value." It is a concept primarily used in combinatorial game theory, particularly in contexts like Nim games and other impartial games. The Mex of a set of non-negative integers is the smallest non-negative integer that is not included in the set.
Meshulam's game is a mathematical game in combinatorial game theory named after the mathematician A. Meshulam. It involves two players taking turns to color squares in a grid, with specific rules that determine the winning conditions based on the colors chosen. The details of the game can vary, but it typically involves strategic decision-making, foresight, and planning to secure a win.
Map-coloring games are combinatorial games that revolve around the classic problem of coloring a map in such a way that adjacent regions (or countries, states, etc.) do not share the same color. The objective is to determine how many colors are needed to color the map in a valid way, following the rules of the game.
Kayles is a mathematical game of strategy that typically involves two players taking turns. The game is played with a row of wooden or virtual "pins." On each turn, a player can knock down either one pin or two adjacent pins. The objective is to be the player who knocks down the last pin, thus winning the game. Kayles is a type of combinatorial game, meaning that it has a well-defined structure and can be analyzed using mathematical techniques from game theory.
Jenga is a popular tabletop game that involves stacking wooden blocks to build a tower. The game consists of 54 rectangular wooden blocks, each measuring 1.5 inches wide, 0.75 inches high, and 3 inches long. Players take turns removing a block from the tower and placing it on top, trying to do so without causing the tower to collapse.
Infinite chess is an extension of traditional chess played on an infinite chessboard, meaning there are no borders or edges to the board. This allows for an endless range of movement and strategies, as pieces can continue to move indefinitely in any direction without constraint. In infinite chess, the basic rules of chess apply, but there are some adjustments to accommodate the vastness of the board.
The concept of an "indistinguishability quotient" often arises in fields such as information theory, cryptography, and mathematical logic. It generally refers to a way to quantify the ability to distinguish between two or more entities, states, or outcomes based on available information. ### In General Terms: 1. **Indistinguishability**: This typically means that two items cannot be reliably differentiated given the available information.
An impartial game is a type of combinatorial game in which the possible moves available to each player depend only on the current state of the game, and not on which player is currently taking their turn. This means that the options available to both players are the same regardless of who is playing. In impartial games, the rules apply equally to both players, and the game ends when there are no legal moves left.
The term "hot game" can refer to a few different concepts depending on the context: 1. **Trending or Popular Games**: In the context of video games, a "hot game" often refers to a title that is currently very popular or trending among players. This could be due to recent releases, updates, or significant events in the gaming community.
Grundy's game, also known as Nim or Nim-like games, is a classic in combinatorial game theory that involves heaps or piles of objects. The game's general setup typically includes several piles, each containing a certain number of objects (like stones). Players take turns removing a certain number of objects from a single pile. The rules can vary, but usually, a player can remove any number of objects from one pile, at least one.
Go is an ancient board game that originated in China over 2,500 years ago. It is played on a grid of intersecting lines, typically 19x19, although smaller boards such as 13x13 and 9x9 are also used. Players take turns placing black or white stones on the intersections of the lines, with the objective of controlling more territory on the board than the opponent. The game is known for its deep strategy and complexity, despite having simple rules.
Genus theory, particularly in the context of algebraic geometry and topology, deals with the concept of genus, which is a topological invariant that characterizes surfaces and, more generally, algebraic varieties. In simpler terms, the genus of a surface refers to the number of "holes" it has. For example: - A sphere has a genus of 0 (no holes). - A torus has a genus of 1 (one hole).
"Games, Puzzles, and Computation" typically refers to a field of study that intersects computer science, mathematics, and logic through the examination of games and puzzles. This field includes analyzing the computational complexity of various games and puzzles, as well as exploring algorithms that can solve them or determine optimal strategies for playing them. ### Key Aspects of the Field: 1. **Game Theory**: This involves the study of strategic interactions between rational decision-makers.
A game tree is a graphical representation used in game theory and artificial intelligence to depict the possible moves in a game and their consequences. It is a tree structure where: - Each node represents a game state, which includes the positions of the pieces, scores, and who's turn it is to move. - Each edge (or branch) represents a possible move that can be made from one game state to another. - The root of the tree represents the initial state of the game.
Game complexity refers to the various dimensions and aspects that determine the intricacy of a game. It encompasses multiple factors, including: 1. **Strategic Depth**: The range of strategies available to players and the implications of their decisions. A game with high strategic depth often requires thoughtful planning and offers multiple ways to achieve victory. 2. **Rules and Mechanics**: The complexity of the game's rules and how they interact can significantly affect player experience.
A fuzzy game typically refers to a game-theoretic model that incorporates concepts from fuzzy set theory. In contrast to traditional game theory, which often relies on precise numerical payoffs and strategies, fuzzy games allow for uncertainty and imprecision in the preferences and strategies of players. ### Key Characteristics of Fuzzy Games: 1. **Fuzzy Payoffs:** In a fuzzy game, payoffs can be represented as fuzzy sets rather than crisp values.
"Futile" is a term that can refer to various concepts in gaming or different contexts, but it is often associated with games that might be characterized by a lack of meaningful progress or rewards. However, there isn’t a widely recognized game specifically named "Futile" that has gained mainstream attention or a specific definition in the gaming community as of my last update in October 2023.
Fibonacci Nim is a variant of the traditional game of Nim, which introduces a unique twist using Fibonacci numbers. In Fibonacci Nim, players take turns removing objects (or stones) from a heap, with the number of objects that can be removed on any turn determined by Fibonacci numbers.
Domineering refers to the behavior or attitude of someone who asserts control over others in an overbearing or authoritative manner. A domineering person often tries to exercise power or influence, making decisions for others or imposing their will on them, often disregarding others' opinions or feelings. This can manifest in various contexts, such as in personal relationships, workplaces, or social situations. Such behavior can lead to an unhealthy dynamic, as it typically creates a power imbalance and can stifle collaboration and communication.
The term "disjunctive sum" can refer to a few different concepts depending on context, but it is commonly associated with areas in mathematics and computer science, particularly in the field of logic and set theory. 1. **Mathematics/Set Theory**: In the context of set theory, a "disjunctive sum" might refer to the union of two or more sets, with the understanding that the sets are disjoint (i.e., they have no elements in common).

Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.
