Early in the 1980s Stephen Wolfram began to work in earnest upon cellular automata. These are a class of computer model which may be visualized as a set of memory locations, each containing one bit. These bits are updated in a succession of time steps. In each step, the new value of each bit depends upon the values of neighboring bits. Wolfram particularly studied the class of automata in which all the bits are arranged upon a line, and each bit is updated using the very same functionalâ€¦Â CONTINUE READING
