Non-regular unary language and parallel communicating Watson-Crick automata systems (1510.02070v1)
Published 7 Oct 2015 in cs.FL
Abstract: In 2006, Czeizler et.al. introduced parallel communicating Watson-Crick automata system. They showed that parallel communicating Watson-Crick automata system can accept the non-regular unary language L={an2 ,where n>1} using non-injective complementarity relation and three components. In this paper, we improve on Czeizler et.al. work by showing that parallel communicating Watson-Crick automata system can accept the same language L using just two components.
