Before revision:  Most existing methods in resilience analysis are based on an iterative approach that explores each node/link of a graph . These methods suffer from high computational complexity and the resulting analysis is network specific.
After revision:  Most existing methods in resilience analysis are based on an iterative approach that explores each node/link of a graph at a time, repeating for all nodes/links in the graph. Such methods suffer from high computational complexity and the resulting analysis is network specific.
