P Colonies of Capacity One and Modularity

Summary. We continue the investigation of P colonies introduced in [8], a class of abstract computing devices composed of independent agents, acting and evolving in a shared environment. The first part is devoted to the P colonies of the capacity one. We present improved allready presented results concerning the computional power of the P colonies. The second part is devoted to the modularity of the P colonies. We deal with dividing the agents into modules.
