  2. List of undecidable problems - Wikipedia

    en.wikipedia.org/wiki/List_of_undecidable_problems

    Conway's Game of Life on whether, given an initial pattern and another pattern, the latter pattern can ever appear from the initial one. Rule 110 - most questions involving "can property X appear later" are undecidable. The problem of determining whether a quantum mechanical system has a spectral gap. [9] [10]

  3. Mathematical problem - Wikipedia

    en.wikipedia.org/wiki/Mathematical_problem

    Such questions are usually more difficult to solve than regular mathematical exercises like "5 − 3", even if one knows the mathematics required to solve the problem. Known as word problems , they are used in mathematics education to teach students to connect real-world situations to the abstract language of mathematics.

  4. List of unsolved problems in mathematics - Wikipedia

    en.wikipedia.org/wiki/List_of_unsolved_problems...

    Many mathematical problems have been stated but not yet solved. These problems come from many areas of mathematics, such as theoretical physics, computer science, algebra, analysis, combinatorics, algebraic, differential, discrete and Euclidean geometries, graph theory, group theory, model theory, number theory, set theory, Ramsey theory, dynamical systems, and partial differential equations.

  5. 24 (puzzle) - Wikipedia

    en.wikipedia.org/wiki/24_(puzzle)

    The original version of 24 is played with an ordinary deck of playing cards with all the face cards removed. The aces are taken to have the value 1 and the basic game proceeds by having 4 cards dealt and the first player that can achieve the number 24 exactly using only allowed operations (addition, subtraction, multiplication, division, and parentheses) wins the hand.

  6. Questions (game) - Wikipedia

    en.wikipedia.org/wiki/Questions_(game)

    Questions is a game in which players maintain a dialogue of asking questions back and forth for as long as possible without making any declarative statements. Play begins when the first player serves by asking a question (often "Would you like to play questions?"). The second player must respond to the question with another question (e.g.

  7. Hydra game - Wikipedia

    en.wikipedia.org/wiki/Hydra_game

    The Buchholz hydra game is a hydra game in mathematical logic, a single player game based on the idea of chopping pieces off a mathematical tree. The hydra game can be used to generate a rapidly growing function (), which eventually dominates all provably total recursive functions. It is an extension of Kirby-Paris hydras.

  8. Gambling mathematics - Wikipedia

    en.wikipedia.org/wiki/Gambling_mathematics

    The mathematics of gambling is a collection of probability applications encountered in games of chance and can get included in game theory.From a mathematical point of view, the games of chance are experiments generating various types of aleatory events, and it is possible to calculate by using the properties of probability on a finite space of possibilities.

  9. Sprouts (game) - Wikipedia

    en.wikipedia.org/wiki/Sprouts_(game)

    A game of sprouts with n initial spots (in blue) that ends in 3n − 1 moves. Each spot starts with three lives and each move reduces the total number of lives in the game by one (two lives are lost at the ends of the line, but the new spot has one life). So at the end of the game there are 3n − m remaining lives.
