This book presents a new concurrent logic programming language called Conclog and a methodology for programming in it. Conclog was designed bytaking the ideal features of logic programming as reference, rather than by concentrating directly on operational tricks to ensure efficiency. This leads to quite easy declarative programming. Concern for soundness and completeness ensures that multi-directional and multi-solution correct procedures can be coded quite straightforwardly. Assuming suitable hypotheses on their uses, they can be transformed into very efficient versions thanks to the...

Modern information systems rely increasingly on combining concurrent, d- tributed, mobile, recon?gurable and heterogenous components. New models, architectures, languages, and veri?cation techniques are therefore necessary to cope with the complexity induced by the demands of today's software devel- ment. Coordination languages have emerged as a successful approach, providing abstractions that cleanly separate behavior from communication and therefore increasing modularity, simplifying reasoning, and ultimately enhancing software development. This volume contains the proceedings of the 7th...
