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.

Tweaking MIT's bitcount algorithm to count words in parallel?

I want to use a version of the well known MIT bitcount algorithm to count neighbors in Conway's game of life using SSE2 instructions. Here's the MIT bitcount in c, extended to count bitcounts > 63 bits. int bitCount(unsigned long long n) { unsigned…

How does the _mm256_shuffle_epi8 make sense in this Game of Life implementation?

Making my homework for implementing Conway's Game of Life using intrinsic functions found the working code, but cannot understand the main part of it. This implementation first calculates amount of alive neighbors for each sell and store the result…

Best way to render a bitmap/bitarray to 2d plane (with OpenGL)

Ok, this is what I have. I have a 1d bitmap (or bitarray, bitset, bitstring, but I'll call it a bitmap for now) containing the live or dead states from a conway game of life generation. The cell at (x, y) is represented by the bit at y * map_width +…

Conways Game of Life in PyGame

So I read about Conways Game of Life and tried to implement it with PyGame. I tried to make it object-oriented. The way it works is that I have a list of cell-instances, which then check how many neighbours they have and then either stay alive or…
