An Adaptive Agent Approach Using Personality and Emotions

Abstract

This paper presents an adaptive model based on emotions and personality, and inspired by human behavior, where the agent emotions and personality vary according to the time and with the interactions. The decision-making actions occur into the environment and with other agents. In this model, the agent personality will be directly related to its own decision making, and the emotions will indirectly influence these decisions. From agent perception, emotions are felt, and from the emotions felt the agent personality changes. In order to study agent behavior, several multi-agent simulations were executed, in different scenarios, to better understand who and why agents exchange resources and consume them to survive. Afterwards, the personality of the other agents was defined, the agent studied modifies their own personality and behavior according to the others. From the results, we identified the adaptability of the agent to the environment in which it lived. This social adaptation was determined by the community in which it was inserted and/or by the environmental factors that it was subject.
