We propose a new conceptual model for choreographies of web-services. Choreographies are seen as virtual workflow models shared among participants. Subsets of these participants mi...
Abstract-- We propose distributed algorithms to automatically deploy a group of robotic agents and provide coverage of a discretized environment represented by a graph. The classic...
