Before revision:  For example, two of the most widely used algorithms, the k-cores decomposition and the classic two-block model of URLatti and Everett, extract fundamentally different structures: the former partitions a network into a binary hub-and-spoke layout, while the latter divides it into a layered hierarchy.
