If anyone feels like trying it themselves -- that would be wonderful -- the code is at http://hampshire.edu/lspector/gptp10/autopush-gptp10-code.zip Open the regression.clj file in success-12, scroll to the bottom, decrease the :population-size parameter near the bottom the file from 100000 to 1000 (just so it goes through generations faster), and then run that file (which will load clojush.clj). Under 1.2 this generally hangs within a couple dozen generations for me... sometimes a little longer. (In case this could matter I'm running under Mac OS X in Eclipse/Counterclockwise, with the most recent versions of everything.) Under 1.1 it runs through at least several hundred generations without error or hanging until I stop it. (It's unlikely with these parameters but it's possible it would stop earlier because it found a solution -- then it would say "Success!".) If anyone does this please note that I do know that the code in that file is TERRIBLE, AWFUL, unidiomatic clojure code. I was still new(er) to clojure when I wrote it. My more recent versions are improved in several ways -- some of that is at http://github.com/lspector/Clojush -- but since I wanted code that ran in 1.1 I'm using this old version to track down this problem. -Lee -- Lee Spector, Professor of Computer Science School of Cognitive Science, Hampshire College 893 West Street, Amherst, MA 01002-3359 lspec...@hampshire.edu, http://hampshire.edu/lspector/ Phone: 413-559-5352, Fax: 413-559-5438 Check out Genetic Programming and Evolvable Machines: http://www.springer.com/10710 - http://gpemjournal.blogspot.com/ -- You received this message because you are subscribed to the Google Groups "Clojure" group.
