Adaptation and Social Facilitation in a Population of Autonomous Robots

摘要

In this paper we present an evolutionary simulation in which a population of 10 mobile robots has to develop a simple behavior consisting in the discrimination of two difierent foraging areas present in the environment. We show that, given a minimal selective pressure, a combination of individual learning, social facilitation, and selection at the population level can lead to efiective results. Consistently with ethological flndings, we argue that such dynamics in which simple mechanisms interact at difierent levels can account for instances of social transmission of behaviors usually interpreted as intentional acts of copying.
