EXPERIMENTAL INVESTIGATION OF AN AGENT COMMITMENT STRATEGY x Martha

نویسنده

چکیده

In dynamic environments, optimal deliberation in the decision-theoretic sense is impossible. Instead, it is sometimes necessary to trade potential decision quality for decision timeliness. One approach to achieving this trade-o is to endow intelligent agents with meta-level strategies that provide them guidance about when to reason| and what to reason about|and when to act instead. In this paper, we describe our investigations of a particular meta-level reasoning strategy, ltering, in which an agent commits to the goals it has already adopted, and then tends to lter from consideration new options that would con ict with the successful completion of existing goals [Bratman et al. 1988]. To investigate the utility of ltering, we conducted a series of experiments using the Tileworld testbed [Pollack and Ringuette 1990]. Previous experiments [Kinny and George 1991] provided preliminary evidence of the feasibility of ltering; our results generalize and re ne those earlier claims to show the types of conditions under which ltering leads to improved performance, and the types of conditions that require restrictions on ltering.

Is "Early Commitment" in Plan Generation Ever a Good Idea?

Partial-Order Causal Link planners typically take a “least-commitment” approach to some decisions (notably, step ordering), postponing those decisions until constraints force them to be made. However, these planners rely to some degree on early commitments in making other types of decisions, including threat resolution and operator choice. We show why existing planners cannot support full least...

Parameterized Action Representation and Natural Language Instructions for Dynamic Behavior Modification of Embodied Agents

We introduce a prototype for building a strategy game. A player can control and modify the behavior of all the characters in a game, and introduce new strategies, through the powerful medium of natural language instructions. We describe a Parameterized Action Representation (PAR) designed to bridge the gap between natural language instructions and the virtual agents who are to carry them out. W...

Toward an AgentSpeak(L) Theory of Commitment and Intentional Learning

This work is about the commitment strategies used by rational agents programmed in AgentSpeak(L) and the relationship between single-minded commitment and intentional learning. Although agent oriented languages were proposed to reduce the gap between theory and practice of Multi-Agent Systems, it has been difficult to prove BDI properties of the agents programmed in such languages. For this rea...

Commitment, Learning, and Alliance Performance: A Formal Analysis Using an Agent-Based Network

Current theoretical arguments highlight a dilemma faced by actors who either adopt a weak or strong commitment strategy for managing their alliances and partnerships. Actors who pursue a weak commitment strategy—i.e. immediately abandon current partners when a more profitable alternative is presented—are more likely to identify the most rewarding alliances. On the other hand, actors who enact a...
