Digital Search Trees Revisited

  title={Digital Search Trees Revisited},
  author={Philippe Flajolet and Robert Sedgewick},
  journal={SIAM J. Comput.},
Several algorithms have been proposed which build search trees using digital properties of the search keys. A general approach to the study of the average case performance of such algorithms is discussed, with particular attention to the analysis of the digital search tree structures of Coffman and Eve. Specifically, the method leads to the solution of a problem left open by Knuth, finding the average number of nodes in digital search trees with both sons null. The paper may be of interest as a… CONTINUE READING
