We say that, a Cellular Automata (CA) is coalescing when its execution on two distinct (random) initial configurations in the same asynchronous mode (the same cells are updated in each configuration at, each time step) makes both configurations become identical after a reasonable time. We prove coalescence for two elementary rules and show that there exists infinitely many coalescing CA. We then conduct, an experimental study on all elementary CA arid show that some rules exhibit a phase transition, which belongs to the universality cliiss of directed percolation. © Springer-Verlag Berlin Heidelberg 2006.
