Hi Jim Using this <https://gist.github.com/swannodette/3217582> version of Davids solver and and the random puzzle generator you refer to the below works for me:
(sudokufd (vec (map #(if (= % \.) 0 (Integer. (str %))) (random-puzzle)))) I did adapt David's solver to work with core.logic 0.8.5, but only changes needed were due to fd being in its own namespace.
