Gabriel Nivasch

Gabriel Nivasch is a theoretical computer scientist and Life enthusiast, born in Venezuela and currently residing in Israel.

His contributions to the Game of Life include the triple and quad pseudo still lifes, found in in July 2001, and Gabriel's p138, the smallest known period 138 oscillator, in October 2002. He also collaborated with David Bell and Jason Summers on the Caterpillar, the first engineered spaceship as well as the first 17c/45 ship.

He devised a stack-based algorithm for memory-efficient cycle detection that can be used to determine the period of oscillators in cellular automata.
