WebJul 10, 2024 · 2. Scale-free networks. Now we’ll move on to the idea of power-law or “scale-free” degree distributions in networks. If you recall, Barabási and Albert (1999) proposed that degree distributions of many real-world networks follow a power-law. This is significant because a major characteristic of a power-law distribution is that you can have some … WebIn the context of network theory, a complex network is a graph (network) with non-trivial topological features—features that do not occur in simple networks such as lattices or random graphs but often occur in networks representing real systems. The study of complex networks is a young and active area of scientific research (since 2000) inspired largely by …
