A MzScheme Implementation of Transition P Systems, a library of procedures have been developed that work in two stages. In the first one, the . stage, the input P system is checked, and if it is well defined, then it is represented by means of an internal grammar. In a second stage, the ., the computation tree associated to the P system is generate

Parallel Rewriting P Systems without Target Conflicts,parallelism methods are used and only rules which have the same target indication can be simultaneously applied to a common string. The computational power is analyzed, with respect to Lindenmayer systems, and some relations among different parallel rewriting P systems are studied. Some open problem

,Evolution–Communication P Systems,es (for communication)..This type of P system is realistic for (at least) three different reasons: we do not have target indications in the evolution rules, we use very simple symport/antiport rules to realize communication, and we do not need objects available in the environment at the beginning of

Dynamic P Systems,al grammars. We introduce the concept of enriched bracketed contextual grammar, which can be used to generate families of P systems with symport/antiport rules..More generally, we define the notion of dynamic P system associated to grammars able to “generate” families of P systems, and introduce the
