1. A machine for improved generation of pseudo-random numbers in a computer system, comprising: a processor or microprocessor coupled to a memory, wherein the microprocessor is programmed to generate a pseudo-random number using only the output from the center bit of a bounded one-dimensional cellular automaton with a fixed span and an extreme left boundary cell and an extreme right boundary cell, wherein a left linear feedback shift register provides continuous input to the extreme left boundary cell; wherein a right linear feedback shift register provides continuous input to the extreme right boundary cell; wherein the left linear feedback shift register and the right linear feedback shift register are uncorrelated and run independently; wherein the cellular automaton is uniform.
