Abstract

Membrane computing has been applied in broad fields such as Biological modeling, NPC problems and combinatorial problems. It has great parallelism and non-determinacy. In this paper, a new variety of P system with chained rules is first applied to the problem of the hierarchical clustering. This new model of P system is designed to solve hierarchical clustering of individuals with nonnegative integer variables. Through performance analysis, this new model of P system can reduce the time complexity of clustering process comparing with the classical clustering algorithm. And it is proved to be more concise and explicit to realize agglomerative hierarchical clustering algorithm by example verification. This is a great improvement in applications of membrane computing.
