Introductory Articles
- Conway's Game of Life at Wikipedia
- Conway's Game of Life at LifeWiki
- What is the Game of Life? at Math.com
- The fantastic combinations of John Conway's new solitaire game "life" - The original article describing Conway's Game of Life. Written by Martin Gardner and published in the October 1970 issue of Scientific American.
Research Papers

Downloadable Computation and/or Search Software
- Catalyst v1.0 by Gabriel Nivasch - Finds ways of modifying the evolution of an input pattern by placing catalysts that react with it, by a backtracking search. Written in C++.
- gencols by Paul Callahan - Enumerates collisions between patterns (e.g. gliders and still lifes). Includes output filters to detect oscillators, spaceships, or successful eating of one pattern by another. Life evolution rule is hardcoded as a sequence of bit-parallel integer operations (so it's possible to change but not easy). Written in C.
- gfind v4.8 by David Eppstein - Search program for low-period spaceships. Extends partial patterns a row at a time, keeping track of rows in all phases of the pattern. Includes modes for finding symmetric patterns. Written in C.
- gsearch by David Eppstein - Performs a brute force search of all patterns fitting within a small rectangle. Evolves each pattern for a specified number of generations or until it repeats, grows too large, or matches a previously seen pattern. Recognizes spaceships, oscillators, unstable oscillators (such as queen bee and p90), replicators, and some puffers. Includes modes for finding symmetric patterns. Written in C.
- Hersrch by Karel Suhajda (via archive.org - the original site is down) - Searches for open or closed Herschel tracks in Conway's Game of Life, using a database of known static and periodic track components. Written in C++.
- lifesrc v3.8 by David Bell - Search program for oscillators. Written in C.
- ofind v0.9 by David Eppstein - Searches for low-period oscillators. Similar to gfind, but extends patterns in all phases simultaneously rather than a single phase at a time, and includes special handling of stator cells. User can specify what spark the oscillator should produce, or how it should interact with neighboring patterns of other periods. Written in C.
- Random Agar v1.1 by Gabriel Navasch - Looks for new Life oscillators, wicks, and agars. Generates random spatially periodic patterns, and runs them until they oscillate. Includes complete support for all possible symmetry types. Written in C++.
