....that commitment to the joint 4 activity is the defining characteristic of collaboration. Although theories differ in the ways they encode this commitment, they agree on its centrality. At the same time, research on rationality and resource bounded reasoning (Bratman et al. 1988; Doyle, 1991; Horty and Pollack, 1998; inter alia) has established the need for agents to dynamically adapt their plans to accommodate new opportunities and changes in the environment. Efforts in this area, however, have mainly focused on plan management and evolution in the context of individual plans. My experiments, like previous ....

....With less committed and more opportunistic agents, the coordination of agents becomes more dicult. But an absolute commitment is not realistic in a dynamic environment. An appropriate response to environmental change depends on valuing the options an agent has with respect to the given context [27]. To become aware about relevant changes in the environment, monitoring strategies have to be realized. e.g. Pollack introduces a rationale based monitoring which focuses the attention of an agent to that part of the environment which is included in the plan rationale and thus likely related to ....

....unable to generate a plan. If the agent had been equipped with a memory and means for belief revision it had been reasonable to equip it with some means to focus its knowledge for plan generation, as well. Thus, our experiments con rm other experiments conducted with agents in complex environments [27]. Obviously, Tileworld o ers a complexity where planning systems react very sensitive to an increase of domain size. Trust in the environment pays in most experimental settings. One should note, that with a restricted view the length of most plans will be less than 10. With a trust of 10 an agent ....

....actions, and then chooses some action whose expected utility is maximal. However, classical decision theory does not completely address certain challenges that arise in designing alternative assessment procedures for agents in dynamic environments. We have been developing a framework that does [Horty and Pollack, 1998], and it differs from classical decision theory in two important ways. First, where decision theory assumes that the utility of an outcome is given as part of the background setting, we observe that the overall desirability of an option presented to an agent is often not immediately apparent; we ....

....may interact with one another, the cost of one activity may vary, depending upon the other activities to which the user has already committed. We have developed and implemented an approach to evaluating the cost of a potential option in the context of existing commitments; details can be found in (Horty Pollack 1998). If activities have known values associated with them, then cost assessment can be used to determine whether an activity is worth pursuing. Our cost assessment algorithm uses cost estimate intervals: as soon as the new activity s value is determined to lie outside the cost estimate interval, it ....

....the step merging decisions in the schedule. In a fashion somewhat reminiscent of the candidate elimination algorithm (Mitchell 1997) our algorithm maintains, for each lattice, frontiers that bound the space of possible legal schedules for the plans. We provide details of our algorithms elsewhere (Horty Pollack 1998). PMA: The Plan Management Agent To further investigate our theories of plan management, including the theory of option evaluation, we have been building a testbed system, the Plan Management Agent (PMA) This system is intended to be a smart assistant , that helps a user manage a potentially ....

....IRMA agents must perform as well. For example, they must deliberate about alternatives that are either compatible with their existing plans or have triggered an override [2] recently, John Horty and I have been developing mechanisms for weighing alternatives in the context of existing plans [10]. Another example is hinted at in my earlier comments: all IRMA agents need to be able to perform means end reasoning. But unlike standard meansend reasoning in AI (plan generation) an IRMA agent must do this reasoning taking account its existing plans. Work on plan merging, notably that of Yang ....
