Dynamic Hierarchies in Temporal Directed Networksven directed network can be formulated as follows: partition vertices into levels such that, ideally, there are only forward edges, that is, edges from upper levels to lower levels. In practice, the ideal case is impossible, so instead we minimize some penalty function on the backward edges. One pra

Think Before You Discard: Accurate Triangle Counting in Graph Streams with Deletionswe obtain unbiased estimates with small variances?.Counting triangles (i.e., cliques of size three) in a graph is a classical problem with applications in a wide range of research areas, including social network analysis, data mining, and databases. Recently, streaming algorithms for triangle counti
