# CNCC - Change Number of Connected Components

#### Definition

A node’s CNCC value represents the
increase of connected components in the whole network.
CC(i) is the number of connected components of the whole
network when removing node u and all its connecting
edges, and CC(0) represents the number of connected components
of the original network.
