Chehalis River in the U.S. state of Washington. Approximately 40 miles (64 km) long, the river drains a remote rural area of approximately 102 square miles (260 km2) in Grays Harbor County along the Washington coast north of Aberdeen. It flows south through the county and empties into the Chehalis at Aberdeen.- Cellular Automata (plato.standford.edu)
Cellular automata (henceforth: CA) are discrete, abstract computational systems that have proved useful both as general models of complexity and as more specific representations of non-linear dynamics in a variety of scientific fields. Firstly, CA are (typically) spatially and temporally discrete: they are composed of a finite or denumerable set of homogeneous, simple units, the atoms or cells. At each time unit, the cells instantiate one of a finite set of states. They evolve in parallel at discrete time steps, following state update functions or dynamical transition rules: the update of a cell state obtains by taking into account the states of cells in its local neighborhood (there are, therefore, no actions at a distance).
