Abstract

This paper presents a new connectionist model that might be used to solve NP-problems. Most well known numeric models are Neural Networks that are able to approximate any function or classify any pattern set provided numeric information is injected into the net. Concerning symbolic information new research area has been developed, inspired by George Paun, called Membrane Systems. A step forward, in a similar Neural Network architecture, was done to obtain Networks of Evolutionary Processors (NEP). A NEP is a set of processors connected by a graph, each processor only deals with symbolic information using rules. In short, objects in processors can evolve and pass through processors until a stable configuration is reach. Despite their simplicity, we show how the latter networks might be used for solving an NP-complete problem, namely the 3-colorability problem, in linear time and linear resources (nodes, symbols, rules).
