Feeding relationships can cause invasions, extirpations, and population fluctuations of a species to dramatically affect other species within a variety of natural habitats. Empirical evidence suggests that such strong effects rarely propagate through food webs more than three links away from the initial perturbation.
We quantify the dynamical implications of the small-world phenomenon. We consider the generic synchronization of oscillator networks of arbitrary topology, and link the linear stability of the synchronous state to an algebraic condition of the Laplacian of the graph. We show numerically that the addition of random shortcuts produces improved network synchronizability.
Two interesting points: 1. The seed set for AltaVista must be at least 10 million (actually, presumably, much larger). Creating a huge seed set almost as important as crawling.2. How on earth does AltaVista find URLs for 10 million isolated pages?
Whuffie is the ephemeral, reputation-based currency of Cory Doctorow's science fiction novel, Down and Out in the Magic Kingdom. A person's current Whuffie is instantly viewable to anyone, as everybody has a brain-implant giving them an interface with the Net.The term has since seen some adoption as a synonym for social capital, including its use...
Six degrees of separation refers to the idea that, if a person is one step away from each person they know and two steps away from each person who is known by one of the people they know, then everyone is an average of six "steps" away from each person on Earth.
Linked is a great book on scale-free networks.Physicist Albert-László Barabási explain How Everything Is Connected to Everything Else and What It Means.This bag will collect many related online sources for this book.
A network that is scale-free will have the same properties no matter what the number of its nodes is. Their defining characteristic is that their degree distribution follows the Yule-Simon distribution — a power law relationship.Here is a pool of best book on Scale-free network.
Self-organization is a process of attraction and repulsion in which the internal organization of a system, normally an open system, increases in complexity without being guided or managed by an outside source. Self-organizing systems typically (though not always) display emergent properties.
