Center node: "a simple local 3 approximation algorithm for vertex cover"
  Abstract: We present a local algorithm (constant-time distributed algorithm) for finding a 3-approximate vertex cover in bounded-degree graphs. The algorithm is deterministic, and no auxiliary information besides port numbering is required.
