Optimal online balanced graph partitioning
WebIn the online balanced graph repartitioning problem, one has to maintain a clustering of n nodes into ℓ clusters, each having k = n / ℓ nodes. During runtime, an online algorithm is given a stream of communication requests between pairs of nodes: an inter-cluster communication costs one unit, while the intra-cluster communication is free. Webalgorithm for graph partitioning that produces a partition of nearly-optimal balance among those approximating a target conductance. In the papers [ST08b] and [ST08a], we proceed to use this graph partitioning algorithm to design nearly-linear time algorithms for sparsifying graphs and for solving symmetric, diagonally-dominant linear systems.
