Editorial [Intro to the Special Issue on Large-scale Networks]

This Special Issue is devoted to the study of large-scale networks. Its object is to encourage circuit theorists towards a more active participation in the solution of large-scale network problems. The range of papers in this issue indicates the breadth of the field. Large-scale networks are regularly encountered in such diverse areas as circuit theory, communications, computer networks, pipelines, transportation, scheduling and distribution, and power. The range of techniques needed to deal with these networks includes combinatorics and graph theory, network topology, mathematical programming, queuing theory, probability theory and statistics, and heuristic programming. Large-scale network theory represents a challenging new research area for theory and application. The readers of this issue are invited to join.
