This book describes and summarizes past work in important areas of combinatorics and computation, as well as gives directions for researchers working in these areas in the 21st century. It contains primarily survey papers and presents original research by Peter Fishburn, Jim Ho Kwak, Jaeun Lee, K H Kim, F W Roush and Susan Williams. The papers deal with some of the most exciting and promising developments in the areas of coding theory in relation to number theory, lattice theory and its applications, graph theory and its applications, topological techniques in combinatorics, symbolic dynamics and mathematical social science. Contents: Monte-Carlo and Quasi-Monte-Carlo Methods for Numerical Integration (H Faure); Theoretical Approaches to Judgement and Choice (P Fishburn); Combinatorial Aspects of Mathematical Social Science (K H Kim & F W Roush); Twelve Views of Matroid Theory (J P S Kung); Enumeration of Graph Coverings, Surface Branched Coverings and Related Group Theory (J H Kwak & J Lee); An Overview of the Poset of Irreducibles (G Markowsky); Number Theory and Public-Key Cryptography (D Pointcheval); Some Applications of Graph Theory (F Roberts); Duality and Its Consequences for Ordered Cohomology of Finite Type Subshifts (K H Kim et al.); Simple Maximum Likelihood Methods for the Optical Mapping Problem (V Danc k & M S Waterman). Readership: Researchers, graduate students and advanced undergraduates in combinatorics and computational mathematics."
