Network theory is the application of graph-theoretic principles to the study of complex, dynamic interacting systems It provides techniques for further analyzing the structure of interacting agents when additional, relevant information is provided. Graphs provide a structural model that makes it possible to analyze and understand how many separate systems act together. Many problems of practical interest can be represented by graphs. The chapters follow each other in a logical manner, the examples are really good, and the explanations are superb. Graph topology can be quantitatively described by a wide variety of measures, some of which are discussed here. A graph which conveys direction on each arc is called a directed graph, while one which conveys no direction or omni direction is an undirected graph. Graph theory plays an important role in electrical modeling of electrical networks, here, weights are associated with resistance of the wire segments to obtain electrical properties of network structures.
