A couple quick suggestions: On my machine, Peter's code runs in 120 seconds. Changing make-tree to return vectors rather than lists reduced time to 47 seconds. Taking out the nil? test (just (if tree branch1 branch2) shaved off a few more seconds. Removing the pattern-matching let in check-tree (use (tree 0), (tree 1), and (tree 2)) reduced time to 33 seconds.
So these minor changes made a big difference. Maybe there's more to do? Also, I get the impression Clojure needs to be started with the -server flag to use all its optimizations. I haven't tried that. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
