Display of three graphs generated with the Barabasi-Albert (BA) model. Each has 20 nodes and a parameter of attachment m as specified. The color of each node is dependent upon its degree (same scale for each graph).

WebMar 10, 2024 · Barabási-Albert (BA) model: The key issue of random graphs is their failure to adequately predict hubs in the network, which are nodes with a very high degree, but with low frequency (also known as the tail of a network distribution). Scale-free networks are generally dominated by a few highly connected hubs .
