Suppose we have a group of Bayesian agents, and suppose that they would like for their group as a whole to be a Bayesian agent as well. Moreover, suppose that those agents want the probabilities and utilities attached to this group agent to be aggregated from the individual probabilities and utilities in reasonable ways. Two ways of aggregating their individual data are available to them, viz.,...

The multiple-agent scheduling problems have received increasing attention recently. However, most of the research focuses on studying the computational complexity of the intractable cases or examining problems with a single criterion. Often a decision maker has to decide the schedule based on multiple criteria. In this paper, we consider a single machine problem where the objective is to minimi...

When knowledge in each agent is represented by an ontology of concepts and relations, concept communication can not be fulfilled through exchanging concepts (ontology nodes). Instead, agents try to communicate with each other through a common language, which is often ambiguous (such as a natural language), to share knowledge. This ambiguous language, and the different concepts they master, give...

Abstract Evolving information te hnologies have brought omputational power and real-time fa ilities into the sto k market. Automated sto k trading draws mu h interest from both the elds of omputer s ien e and of business, sin e it promises to provide superior ability in a trading market than any individual trader. Trading strategies have been proposed and pra ti ed from the perspe tives of Arti...

Copiamycin, a macrocyclic lactone antifungal antibiotic, was found to potentiate the antifungal effect of imidazole compounds, ketoconazole in particular. The potentiation of two nominally fungistatic agents in vitro was substantiated by a marked reduction of the minimum inhibitory and minimum fungicidal concentrations when the drugs were used in combination. The effectiveness of this synergist...

Two agents previously unknown to each other cannot communicate by exchanging concepts (nodes of their own ontology): they need to use a common communication language. If they do not use a standard protocol, most likely they use a natural language. The ambiguities of it, and the different concepts the agents possess, give rise to imperfect understanding among them: How closely concepts in ontolo...

Strong Nash equilibrium (SNE) is an appealing solution concept when rational agents can form coalitions. A strategy profile is an SNE if no coalition of agents can benefit by deviating. We present the first general– purpose algorithms for SNE finding in games with more than two agents. An SNE must simultaneously be a Nash equilibrium (NE) and the optimal solution of multiple non–convex optimiza...

Two novel antifungal agents belonging to the sordarin family have been isolated from fermentations of Sordaria araneosa by bioassay-guided purification and their structures elucidated by NMR techniques. Neosordarin (1) is closely related to the recently discovered hypoxysordarin (2), with only small differences on the aliphatic side chain acylating the hydroxyl in the 3'-position of the sordaro...

We propose two mechanisms for agent learning based on the idea of mining temporal patterns from agent behavior. The first one consists of extracting temporal patterns from the perceived behavior of other agents accomplishing a task, to learn the task. The second learning mechanism consists in extracting temporal patterns from an agent’s own behavior. In this case, the agent then reuses patterns...
