Query: Tourneys and the Fast Generation and Obfuscation of Closed Knight's
  Tours   New algorithms for generating closed knight's tours are obtained by
generating a vertex-disjoint cycle cover of the knight's graph and joining the
resulting cycles. It is shown experimentally that these algorithms are
significantly faster in practice than previous methods. A fast obfuscation
algorithm for closed knight's tours that obscures obvious artifacts created by
their method of generation is also given, along with visual and statistical
evidence of its efficacy.
