WebA graph generated by the binomial model of Erdős and Rényi ( p = 0.01) In the model, a graph is chosen uniformly at random from the collection of all graphs which have nodes and edges. The nodes are considered to be labeled, meaning that graphs obtained from each other by permuting the vertices are considered to be distinct. For example, in the WebGenerates and returns a random small-world graph using the Watts-Strogatz model. We assume a circle where each node creates links to NodeOutDeg other nodes.

WebThe Small World Random Graph Model In 1998, Duncan J. Watts and Steven Strogatz came up with a model for constructing a family of networks with both high clustering and short average path length. They termed this model the ‘‘small world model’’. To create such a model, we employ the following steps: WebThe Barabási–Albert model is one of several proposed models that generate scale-free networks. It incorporates two important general concepts: growth and preferential attachment. Both growth and preferential attachment exist widely in real networks. Growth means that the number of nodes in the network increases over time.
