LP-Based Robust Algorithms for Noisy Minor-Free and Bounded Treewidth   Graphs
  We give a general approach for solving optimization problems on noisy minor free graphs, where a \delta-fraction of edges and vertices are adversarially corrupted. The noisy setting was first considered by Magen and Moharrami and they gave a (1 + \delta)-estimation algorithm for the independent set problem. Later, Chan and Har-Peled designed a local search algorithm that finds a (1 + O(\delta))-approximate independent set. However, nothing was known regarding other problems in the noisy setting. Our main contribution is a general LP-based framework that yields a (1 + O(\delta log m log log m))-approximation algorithm for noisy MAX-k-CSPs on m clauses.
