In this paper we discuss the experimental evaluation of an improved configuration of our recent framework ACODA (Ant Colony Optimization on a Distributed Architecture) for solving the Traveling Salesman Problem (TSP). ACODA is a novel multi-agent system architecture for distributed Ant Colony Optimization in a decentralized environment. This new(More)
Collaboration workflows for human experts involved in distributed problem solving and acting in dynamic environments require advanced self-configuration mechanisms for optimal selection of service providers. Such dynamic environments, specific for example to problems like environmental management, disaster and crisis management, and high-risk project(More)
This paper presents a framework of ICT solutions developed in the EU research project DIADEM that supports environmental management for chemical hazards in industrial areas, with an enhanced capacity to assess population exposure and health risks, alert relevant groups and organize efficient response. The emphasis is on advanced solutions which are(More)
Recently we were involved in the development of a distributed agent-based English auction server. The focus of the work was on emphasizing the advantages brought by the multi-agent systems technology to the high-level of abstraction, modularity and performance of the server architecture, and its implementation. Less effort was spent on the analysis of its(More)
Recently we have setup the goal of investigating new truly distributed forms of Ant Colony Optimization.We proposed a new distributed approach for Ant Colony Optimization (ACO) algorithms called Ant Colony Optimization on a Distributed Architecture (ACODA). ACODA was designed to allow efficient implementation of ACO algorithms on state-of-the art(More)
This paper presents a distributed agent-based server architecture for English auctions. Bids of auction participants are handled by a hierarchical organization of agents that can be efficiently distributed on a computer network. This approach avoids the bottlenecks of bid processing that might occur during periods of heavy bidding, like for example(More)
The paper presents a semantic logging framework which allows structured information logging in an agent-based distributed system for chemical incident response. The logging framework is “semantic” because it allows semantic interpretation of logs according to relationships defined between logging events. For example, this approach could help(More)
