An extraordinary variety of disciplines rely on graphs to convey their fundamentals as well as their finer points. With this concise and well-written text, anyone with a firm grasp of general mathematics can follow the development of graph theory and learn to apply its principles in methods both formal and abstract. The work of a distinguished mathematician, this text uses practical examples to illustrate the theory's broad range of applications, from the behavioral sciences, information theory, cybernetics, and other areas, to mathematical disciplines such as set and matrix theory. 1966 edition. 109 black-and-white illustrations.
