Application Prospects of Metabolic P System

Darius Kulakovskis (Vilnius Gediminas Technical University, Lithuania)


Metabolic P (MP) systems are a class of P systems and are based on metabolic process which is used by living organisms. We review for the purpose of experimental research the MP system development, implementation and modeling. To implement MP systems in dedicated hardware, some specifications need to be determined. We look into the possibility of modeling MP systems in fixed point arithmetic capable hardware and determine the minimal needed bit count for selected MP system model. A way to improve the accuracy of fixed point calculations is proposed, which includes the modification of MP grammar. This modification is done using a simple rule to multiply and divide constants in MP grammar equations. The resulting calculations have more than 250 times smaller error when compared to original calculations. When investigating the performance of MP calculations, it is determined that the time needed for all calculations to finish depends linearly on the number of modeled systems.
