A set of networks that satisfies given structural characteristics can be treated as a network ensemble.[1] Brought up by Ginestra Bianconi in 2007, the entropy of a network ensemble measures the level of the order or uncertainty of a network ensemble.[2]
The entropy is the logarithm of the number of graphs.[3] Entropy can also be defined in one network. Basin entropy is the logarithm of the attractors in one Boolean network.[4]
Employing approaches from statistical mechanics, the complexity, uncertainty, and randomness of networks can be described by network ensembles with different types of constraints.[5]
