How Learning Improves the Performance of Evolutionary Agents: a Case Study with an Information Retrieval System for a Distributed Environment



The goal of this work is to study how individual learning helps adaptive agents, living in an Artificial Life world, to develop correct behaviors when seeking for information in distributed and dynamic environments. We developed a prototype of an information retrieval system where a population of adaptive organisms browses through the environment, trying to find relevant information for a specific query. Two learning procedures are proposed and their effect is studied in different situations. Experimental results show that changes induced by learning provide an important advantage.
