This page is under construction. Sorry for the inconvenience.

This is a list of search programs used with cellular automata.

Modern programs

Name Author Rulespace Can find Description Link Year (creation - last updated)
apgsearch Adam P. Goucher Versatile Natural/semi-natural objects Runs random seeds in an infinite universe and censuses the results.
Results are uploaded to Catagolue.
GitLab repo 2015 - 2024
Barrister Mitchell Riley Life only Catalysed reactions, signal circuitry An advanced, faster version of Bellman/dr2 using LifeAPI. GitHub repo 2022 - 2025
CatForce Michael Simkin and Mitchell Riley Life only Catalysed reactions, oscillators Searches for catalyses by systematically placing catalysts next to an active region.
Allows for transparent catalysts and symmetrical reactions.
GitHub repo 2015 - 2022
ikpx2 Adam P. Goucher Versatile Spaceships Short for Incremental Knightship Partial eXtender, searches for spaceships using several different algorithms. Its predecessor, ikpx, was used to find Sir Robin. Can automatically submit to Catagolue. GitLab repo 2020 - 2024
qfind Matthias Merzenich Isotropic Orthogonal spaceships A multithreaded tree spaceship searcher which employs ideas from gfind and ntzfind. Used to find 139P7H1V0. GitHub repo 2019 - 2025
rlifesrc AlephAlpha Generations, Isotropic Small patterns A versatile program which can find small oscillators, spaceships, and other patterns.
Also avaliable as a web-based program.
GitHub repo

Historical programs

The below list contains programs which are old and not in common use due to being outclassed by modern programs.

Name Author Rulespace Can find Description Link Year (creation - last updated)
CollisionsSearch Guam Life only Catalysed reactions A Windows-only GUI search program with a similar algorithm to CatForce.
Used to discover the semi-Snark along with many new Herschel conduits.
Forum post 2013 - 2016
