Description: Information, money, and disease are disseminated through systems arising both in nature and our technical society. Such systems are modeled by graphs in which objects of interest are represented by vertices connected by edges. In such systems, the notion of connectivity is perhaps the most important property, and a variety of fields, from quantum physics to disease epidemiology, display a similar underlying structure. Highly connected networks are called small-world networks. Diverse examples of such small-world networks with these properties include the World Wide Web as a network of websites, the brain as a network of neurons, and an organization as a network of people. To design networks, modelers will determine appropriate vertices and edges to represent the system and then employ network optimization techniques to develop an optimal design. COSMOS has studied small-world and scale-free networks, measures of a network’s complexity and connectivity, and telecommunications networks.
