Node deletion
Node deletion is the procedure of removing a node from a network, where the node is either chosen randomly or directly. Node deletion is used to test the robustness and the attack tolerance of networks. Understanding how a network changes in response to node deletion is critical in many empirical networks. Application varies across many fields, including the breakdown of the World Wide Web via router removal, elimination of epidemics or fighting against criminal organizations.
==Random deletion==
Removing a node or multiple nodes randomly from a network means that the elimination of a set of nodes happen with a certain probability. The probability of deleting a node can follow any distributions, the most common is to assume a uniform distribution. The effect of the node deletion is highly dependent on the topology of the network, so it affects every empirical networks differently.〔Barabási, A.-L.
