The Game of Life, also known simply as Life, is a cellular automaton devised by the British mathematician John Horton Conway in 1970. The "game" takes place on a 2D grid made up of cells that may either be "alive" or "dead". At each iteration, the state of each cell is computed based on the states of the cell and its 8 neighbors at the previous iteration.

From Wikipedia:

The Game of Life, also known simply as Life, is a cellular automaton devised by the British mathematician John Horton Conway in 1970.

The "game" is a zero-player game, meaning that its evolution is determined by its initial state, requiring no further input. One interacts with the Game of Life by creating an initial configuration and observing how it evolves.

Dealing with large distance between cells in Hashlife

I am writing an implementation of Conway's Game of Life and decided to use a variation of the Hashlife algorithm, using quadtrees and a hashtable to store cells and handle collisions, somewhat similar to what is described here and here. The details…

Conway's Game of Life New Values

The question revolves around Conway's Game of Life and how to implement all the rules at the same time for the new generations. The game follows three rules for new generations, which are: a dead cell with exactly three live neighbors becomes live,…

Making a 2D array toroidal

How can I make the array toroidal (wrap bottom to top and left to right), i.e the leftmost cell is regarded as the rightmost cell, like [0][0] and [5][5] are the same cells in int array[5][5]

How does the hashlife alg go on forever in Golly?

In hashlife the field is typically treated as a theoretically infinite grid, with the pattern in question centered near the origin. A quadtree is used to represent the field. Given a square of 2^(2k) cells, 2k on a side, at the kth level of the…

Explain the use of yields in this Game of Life implementation

In this PyCon talk, Jack Diederich shows this "simple" implementation of Conway's Game of Life. I am not intimately familiar with either GoL or semi-advanced Python, but the code seems quite easy to grasp, if not for two things: The use of yield. I…

Getting values from previous "row" in 2D C array

I'm working on a 1D Game of Life (based upon the rules set out here at Mathworld). Essentially, each generation is represented as a row of 0's or 1's (dead or alive) and the next generation is created based upon the binary representation of a "rule"…
