    We present an update operation, syntactic update, based on Winslett's Possible Models Approach (PMA). The PMA receives a set of propositional formulas describing a situation of the world, and a set of formulas describing the postconditions of an action, and determines the set of models describing the possible states of the world after the execution of the action. In this paper we describe a way of... View full abstract»

    Planning problems, in which a sequence of actions are sought to go from a given state to a desired final state, or goal, have traditionally been hard to handle computationally. In particular and in the most usual case, the goal is not just to find a satisfying plan, but rather to find the best one. Searching for such optimum, i.e. shortest, plan, increases complexity even further. Frequently, spec... View full abstract»

    This work is based on the multimodal logic L(MQ), recently introduced, which formalizes order-of-magnitude qualitative reasoning. The aim of this paper is to provide a sound and complete tableau method for the future fragment of L(MQ) View full abstract»

    In this paper we present the emotional-BDI architecture, an extension to the BDI architecture supporting artificial emotions and including internal representations for agent's capabilities and resources. The architecture we present here is conceptual, defining which components should exist so that emotional-BDI agents can use effective capabilities as well as effective resources in order to better...

  • The role of Surprise, Curiosity and Hunger on Exploration of Unknown Environments Populated with Entities

    This paper describes an approach based on affect to the problem of exploring unknown environments populated with entities by agents. To this end, a multi-agent system based on the notion of affect as well as on the belief-desire-intention (BDI) model was used. The affective component of the agents is confined to the motivations that are usually associated to exploratory behavior: surprise, curiosi... View full abstract»

    We are interested in developing A-Life-like models to study the evolution of emotional systems in artificial worlds inhabited by autonomous agents. This paper focuses on the emotional component of an agent at its very basic physical level. We adopt an evolutionary perspective by modelling the agent based on biologically plausible principles, whereby emotions emerge from homeostatic mechanisms. We ... View full abstract»
