Abstract

Evaluation of permanents of some(0,1) circulants is known to be of major importance for designers of certain speech scrambling systems. In this paper we gicve a lower bound for the number of scaram-bling patterns we deal with by minimizing the permanent function over some matrix polyhedra.
