Center node: "two approaches to the construction of deletion correcting codes weight partitioning and optimal colorings"
  Abstract: We consider the problem of constructing deletion correcting codes over a binary alphabet and take a graph theoretic view. An n-bit s-deletion correcting code is an independent set in a particu lar graph. We propose constructing such a code by taking the union of many constant Hamming weight codes. This results in codes that have additional structure. Searching for cod es in constant Hamming weight induced subgraphs is computationally easier than searching the original graph. We prove a lower bound on size of a codebook constructed this way for any number of deletions and show that it is only a small factor below the corresponding lower bound on unrestricted codes. In the single deletion case, we find optimal colorings of the constant H amming weight induced subgraphs. We show that the resulting code is asymptotically optimal. We discuss the relationship between codes and colorings and observe that the VT codes are optimal in a coloring sense. We prove a new lower bound on the chromatic number of the deletion channel graphs. Colorings of the deletion channel graphs that match this bound do not necessarily produce asymptotically optimal codes.
