Refined Memorisation for Vertex Cover

  title={Refined Memorisation for Vertex Cover},
  author={L. Sunil Chandran and Fabrizio Grandoni},
Memorisation is a technique which allows to speed up exponential recursive algorithms at the cost of an exponential space complexity. This technique already leads to the currently fastest algorithm for fixed-parameter vertex cover, whose time complexity is O(1.2832k + kn), where n is the number of nodes and k is the size of the vertex cover. Via a refined use of memorisation, we obtain a O(1.2759k + kn) algorithm for the same problem. We moreover show how to further reduce the complexity to O(1… CONTINUE READING
