If we consider social interactions among individuals in the Penna model, the population will form a complex network. In this paper, we first modify the Verhulst factor to control only the birth rate, and introduce activity-based preferential reproduction of offspring in the Penna model. The social interactions among individuals are generated by both inheritance and activity-based preferential increase. Then we study the properties of the complex network generated by the modified Penna model. We find that the resulting complex network has a small-world effect and the assortative mixing property.", "revisions": [ { "version": "v1", "updated": "2005-10-25T02:47:42.000Z" } ], "analyses": { "keywords": [ "complex networks", "assortative mixing", "penna model", "small-world", "social interactions" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
