WebIn this Letter we study the diameter of scale-free random networks and show that it is signiﬁcantly smaller than the diameter of regular random networks. We ﬁnd that scale free networks with 2 < λ < 3 have diameter d ∼ lnlnN and thus can be considered as “ultra small world” networks. Websmall-world and scale-free graphs, and then we compare these characteristics with some real-world network data [2], [3]. Definitions As networks despite of their diversity are driven by a common set of laws and principles, there are models that can describe them. Small-world networks and scale-free networks are important complex network

WebMar 24, 2024 · A scale-free network is a connected graph or network with the property that the number of links k originating from a given node exhibits a power law distribution P(k)∼k^(-gamma). A scale-free network can be constructed by progressively adding nodes to an existing network and introducing links to existing nodes with preferential … WebThe scale-free nature of protein-protein interaction networks gives them a number of important features: Stability. If failures occur at random, and the vast majority of proteins are those with a small degree of connectivity, the likelihood that a hub would be affected is small.
