Note that that Igor Korshunov (the guy who beat Martin Fierz in give-away checkers!) also gives perft(14) = 7978439499 for American checkers. A post from 2006.

nihil sub sole novum

But it is always good to see the numbers confirmed. By the way, here is my divide for d=18 to confirm Ed's previous posting (Ed I would advise to use smaller ASCII boards in your output to avoid long pages that require scrolling):

Code: Select all

divide(18) =>
  0  : 12-16 : nodes=550829166472
  1  : 11-16 : nodes=566149929068
  2  : 11-15 : nodes=435063007630
  3  : 10-15 : nodes=472279451484
  4  : 10-14 : nodes=402570639569
  5  :  9-14 : nodes=441590753001
  6  :  9-13 : nodes=625398758917
=> perft(18) = 3493881706141
