Center node: "rate distortion for ranking with incomplete information"
  Abstract: We study the rate-distortion relationship in the set#R##N#of permutations endowed with the Kendall t-metric and the#R##N#Chebyshev metric. Our study is motivated by the application of permutation rate-distortion to the average-case and worst-case analysis of algorithms for ranking with incomplete information and approximate sorting algorithms. For the Kendall t-metric we provide bounds for small, medium, and large distortion regimes, while for the Chebyshev metric we present bounds that are valid for all distortions and are especially accurate for small#R##N#distortions. In addition, for the Chebyshev metric, we provide a construction for covering codes.
