has gloss | eng: Brians Brain is a cellular automaton devised by Brian Silverman, which is very similar to his Seeds pattern. It consists of an infinite two-dimensional grid of cells, but unlike Seeds, each cell may be in one of three states: on, dying, or off. Each cell is considered to have eight neighbors (Moore neighborhood), as in Seeds and Conways Game of Life. In each time step, a cell turns on if it was off but had exactly two neighbors that were on, just like the birth rule for Seeds. All cells that were on go into the dying state, which is not counted as an "on" cell in the neighbor count, and prevents any cell from being born there. Cells that were in the dying state go into the off state. |
