We analyze P systems with different parallel methods for string rewriting. The notion of deadlock state is introduced when some rules with mixed target indications are simultaneously applied on a common string. The computational power of systems with and without deadlock is analyzed and a lower bound for the generative power is given, for some parallelism methods. Some open problems are also formulated.

Abstract
We analyze P systems with different parallel methods for string rewriting. The notion of deadlock state is introduced when some rules with mixed target indications are simultaneously applied on a common string. The computational power of systems with and without deadlock is analyzed and a lower bound for the generative power is given, for some parallelism methods. Some open problems are also formulated.Pubblicazioni consigliate
