This volume comprises the proceedings of the FirstAll-Berlin Workshop on Nonclassical Logics and InformationProcessing, held at the Free University of Berlin, November9-10, 1990.The scope of the ten papers in the volume is broad, coveringvarious different subfields of logic - particularlynonclassical logic - and its applications in artificialintelligence. The papers are grouped according to the fourmajor topics that emerged at the meeting: modal systems, logic programming, nonmonotonic logics, and proof theory.The classification is only a rough guide since the fourareas overlap considerably.

This volume contains the proceedings of JELIA '92, lesJourn es Europ ennes sur la Logique en IntelligenceArtificielle, or the Third European Workshop on Logics inArtificial Intelligence.The volume contains 2 invited addresses and 21 selectedpapers covering such topics as: - Logical foundations of logic programming andknowledge-based systems, - Automated theorem proving, - Partial and dynamic logics, - Systems of nonmonotonic reasoning, - Temporal and epistemic logics, - Belief revision.One invited paper, by D. Vakarelov, is on arrow logics, i.e., modal logics for representing graph...

This volume constitutes the proceedings of the 1994 European Workshop on Logics in Artificial Intelligence, held in September 1994. The work has been divided into sections on non monotonic reasoning, automated reasoning, logic programming, knowledge representation and belief revision.

For those who love poetry, David R.A Pearce has written a unique, beautiful, and impressive collection of sonnets (103 in all) and other poems in 'The Street.' The poems, together, form a very personal and honest account of a challenging and interesting period in his life. 'The Street', off Whitstable, Kent, is an enticing narrow promontory of shingle, shell and pudding-stone extending some mile, or mile and a half, into the sea. It is completely covered at high tide, with rising waters encroaching from both sides. One has to be careful not to be cut off. David Pearce 'The Street' is in...
