Center node: "streaming balanced graph partitioning for random graphs"
  Abstract: There has been a recent explosion in the size of stored data, partially due to advances in storage technology, and partially due to the growing popularity of cloud-computing and the vast quantities of data generated. This motivates the need for streaming algorithms that can compute approximate solutions without full random access to all of the data. #R##N#We model the problem of loading a graph onto a distributed cluster as computing an approximately balanced $k$-partitioning of a graph in a streaming fashion with only one pass over the data. We give lower bounds on this problem, showing that no algorithm can obtain an $o(n)$ approximation with a random or adversarial stream ordering. We analyze two variants of a randomized greedy algorithm, one that prefers the $\arg\max$ and one that is proportional, on random graphs with embedded balanced $k$-cuts and are able to theoretically bound the performance of each algorithms - the $\arg\max$ algorithm is able to recover the embedded $k$-cut, while, surprisingly, the proportional variant can not. This matches the experimental results in [25].
