Artificial immune system is a rapidly growing field of information processi
ng and computing based upon immune inspired paradigms of nonlinear dynamics
. This paper introduces stochastic models which mimic the phenomenology of
basic functions of immune systems such as self-nonself discrimination, self
-repair, predator-prey pursuit, and reproduction. These models represent a
unified formalism for building an artificial immune system for effective in
formation processing and computing. (C) 2000 Elsevier Science Inc. All righ
