Does chaos work better than noise?

Abstract

Chaos and random signals share the property of long term unpredictable irregular behavior and broad band spectrum. The aim of this paper is not to distinguish between random and chaotic dynamics, nor to show the use of chaos, but to focus attention on how chaos and noise help order to arise from disorder It means to investigate the effect of the introduction of either deterministic chaotic or random sequences in different types of phenomena. In particular the results related to different applications, self-organization in arrays of locally coupled systems in which a chaotic dissymmetry is present, chaos driven optimization strategies, pattern formation in Drosophila embryos and some new topics on game theory are treated with the aim to investigate the subject: "does chaos work better than noise?".
