Abstract

In this paper we investigate the notion of nonlinear complexity, or maximal order complexity as it was first defined in 1989 [4]. Our main purpose is to begin classification of periodic binary sequences into nonlinear complexity classes. Previous work on the subject also includes approximation of the size of each class, found in [2]. Once the classification is completed, we can use it to show how to perform checks for short cycles in large nonlinear feedback shift registers using our proposed algorithm.
