Purpose Searching for spaceships

Platform Platform-independent C

gfind is a program by David Eppstein which uses de Bruijn graphs to search for new spaceships. It was with gfind that Eppstein found the weekender, and Paul Tooke later used it to find the dragon.

An edited version of gfind, dubbed zfind, was used by 'zdr' to discover the copperhead spaceship.
