Critical point (network science) : ウィキペディア英語版 | Critical point (network science) In network science, a critical point is a value of average degree, which separates random networks that have a giant component from those that do not (i.e. it separates a network in a subcritical regime from one in a supercritical regime). Considering a random network with an average degree the critical point is
where the average degree is defined by the fraction of the number of edges () and nodes () in the network, that is . == Subcritical regime ==
In a subcritical regime the network has no giant component, only small clusters. In the special case of the network is not connected at all. A random network is in a subcritical regime until the average degree exceeds the critical point, that is the network is in a subcritical regime as long as .
