Can you quantify that randomness? Should it be uniform at each level? Thinking about this may be fruitful. I don't yet know whether you need to see all leaves before you know which subtree to choose. Because I am a clueless American, so I don't know if Piñero is a common name or not. Are you perhaps related to the playwright? --Scott David Daniels [EMAIL PROTECTED] -- http://mail.python.org/mailman/listinfo/python-list
