Abstract

We consider spiking neural P systems with astrocytes producing calcium that differs from the standard spiking neural P systems in several ways: we have a new type of resources called calcium unit alongside the standard spike, we have a new type of place called astrocyte alongside the standard neurons and we also have dedicated synapses for communicating calcium units alongside those used for communicating spikes. In order to illustrate how these systems work we give an example of a spiking neural P system with astrocytes producing calcium that generates all even numbers using only two neurons and one astrocyte and without using either forgetting rules or delay in the evolution rules. We prove that in this framework, we can provide semi-uniform and uniform constructions of spiking neural P system with astrocytes producing calcium working in a non-deterministic way that are able to solve the subset sum problem in a polynomial number of steps without using either forgetting rules or delay in the evolution rules.
