Heterogeneous Multi-Population Cultural Algorithm (HMP-CA) is a new class of Multi-Population Cultural Algorithms which incorporates a number of local Cultural Algorithms (CAs) designed to optimize different subsets of the dimensions of a given problem. In this article, various dimension decomposition techniques for HMP-CAs are proposed and compared. The concept of using a dimension decompositi...

Human language may have started from a consistent set of mappings between meanings and signals. These mappings, referred to as the early vocabulary, are considered to be the results of conventions established among the agents of a population. In this study, we report simulation models for investigating how such conventions can be reached. We propose that convention is essentially the product of...
