Ingo Althöfer
Ingo Althöfer (born 1961) is a German mathematician at the University of Jena, where he holds the chair of operations research. Althöfer earned his PhD in 1986 at Bielefeld University. His dissertation, ''Asymptotic Properties of Certain Competition Systems in Artificial Intelligence and Ecology'', was supervised by Rudolf Ahlswede. Contributions Topics in Althöfer's professional research include the realization of finite metric spaces by shortest path metrics in graphs and their approximation by greedy spanners, algorithmic game theory and combinatorial game theory, and heuristic search algorithms for optimization problems. Althöfer is also known for his inventions of games and puzzles, including dice game EinStein würfelt nicht!, for his experiments with self-assembly of Lego building blocks by running them through a washing machine, and for his innovations in computer-human chess playing. In the 1990s he tested his "drei hirn" 3-brains"system, in which a human decid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
David Bronstein
David Ionovich Bronstein (russian: Дави́д Ио́нович Бронште́йн; February 19, 1924 – December 5, 2006) was a Soviet and Ukrainian chess player.

Clobber
Clobber is an abstract strategy game invented in 2001 by combinatorial game theorists Michael H. Albert, J.P. Grossman and Richard Nowakowski. It has subsequently been studied by Elwyn Berlekamp and Erik Demaine among others. Since 2005, it has been one of the events in the Computer Olympiad. Details Clobber is best played with two players and takes an average of 15 minutes to play. It is suggested for ages 8 and up. It is typically played on a rectangular white and black checkerboard. Players take turns to move one of their own pieces onto an orthogonally adjacent opposing piece, removing it from the game. The winner of the game is the player who makes the last move (i.e. whose opponent cannot move). To start the game, each of the squares on the checkerboard is occupied by a stone. White stones are placed on the white squares and black stones on the black squares. To move, the player must pick up one of his or her own stones and "clobber" an opponent's stone on an adjacent squ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galton Board
The Galton board, also known as the Galton box or quincunx or bean machine, is a device invented by Sir Francis Galton to demonstrate the central limit theorem, in particular that with sufficient sample size the binomial distribution approximates a normal distribution. Among its applications, it afforded insight into regression to the mean or "reversion to mediocrity". Description The Galton board consists of a vertical board with interleaved rows of pegs. Beads are dropped from the top and, when the device is level, bounce either left or right as they hit the pegs. Eventually they are collected into bins at the bottom, where the height of bead columns accumulated in the bins approximate a bell curve. Overlaying Pascal's triangle onto the pins shows the number of different paths that can be taken to get to each bin. Large-scale working models of this device created by Charles and Ray Eames can be seen in the '' Mathematica: A World of Numbers... and Beyond'' exhibits permane ...

Connect Four
Connect Four (also known as Connect 4, Four Up, Plot Four, Find Four, Captain's Mistress, Four in a Row, Drop Four, and Gravitrips in the Soviet Union) is a two-player connection board game, in which the players choose a color and then take turns dropping colored tokens into a seven-column, six-row vertically suspended grid. The pieces fall straight down, occupying the lowest available space within the column. The objective of the game is to be the first to form a horizontal, vertical, or diagonal line of four of one's own tokens. Connect Four is a solved game. The first player can always win by playing the right moves. The game was first sold under the ''Connect Four'' trademark by Milton Bradley in February 1974. Gameplay A gameplay example (right), shows the first player starting Connect Four by dropping one of their yellow discs into the center column of an empty game board. The two players then alternate turns dropping one of their discs at a time into an unfilled colum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freestyle Chess
Advanced chess is a form of chess in which each human player uses a computer chess program to explore the possible results of candidate moves. Despite this computer assistance, it is the human player who controls and decides the game. Also called cyborg chess or centaur chess, advanced chess was introduced for the first time by grandmaster Garry Kasparov, with the aim of bringing together human and computer skills to achieve the following results: * increasing the level of play to heights never before seen in chess; * producing blunder-free games with the qualities and the beauty of both perfect tactical play and highly meaningful strategic plans; * offering the public an overview of the mental processes of strong human chess players and powerful chess computers, and the combination of their forces. A variant or superset of advanced chess is freestyle chess, in which teams are also allowed and, within the established time limits, every possible form of consultation. Freestyle ches ...
