Center node: "the computability path ordering the end of a quest"
  Abstract: In this paper, we first briefly survey automated termination proof methods for higher-order calculi. We then concentrate on the higher-order recursive path ordering, for which we provide an improved definition, the Computability Path Ordering. This new definition appears indeed to capture the essence of computability arguments \`a la Tait and Girard, therefore explaining the name of the improved ordering.
