In previous work we proposed an approach for computing an agentýs preferences over different schedules of tasks, and for soliciting desirable bid combinations to cover the tasks. The proposed approach finds schedules that maximize the agentýs Expected Utility. The maximization problem is hard because the domain is piece-wise continuous, with the(More)
In this paper we are interested in the decision problem faced by an agent when requesting bids for collections of tasks with complex time constraints and interdependencies. In particular, we study the problem of specifying an appropriate schedule for the tasks in the request for bids. We expect bids to require resource commitments, so we expect different(More)
In related research we have proposed a market architecture for multi-agent contracting and we have implemented prototypes of both the market architecture and the agents in a system called MAGNET. A customer agent in MAGNET solicits bids for the execution of multi-step plans, in which tasks have precedence and time constraints, by posting a Request for(More)
In our previous research we suggested an approach to maximizing agents preferences over schedules of multiple tasks with temporal and precedence constraints. The proposed approach is based on Expected Utility Theory. In this paper we address two mutually dependent questions: (a) what are the properties of the problem domain that can facilitate efficient(More)
We propose an evolutionary framework for studying agents that interact in electronic marketplaces and describe how to use the framework to study the dynamics of interaction and evolution of agent strategies. We present experimental results from a simulated market, where service providers compete for customers using multiple strategies. The results show how(More)
We present an auction-based approach to allocate tasks that have complex time constraints and interdependencies to a group of cooperative agents. The approach combines the advantages of planning and scheduling with the ability to make distributed decisions. We focus on methods for modeling and evaluating the decisions an agent must make when deciding how to(More)
The activity of cytochrome oxidase in tissues was decreased in short-term adaptation to reduce pO2 and administration of KCN in small doses. In the former case the activities of peroxidase and catalase were increased in blood. These effects as well as administration of Na2ATP into rats led to an increase in water content in tissues, to soption of acidic(More)
