I think the question of the mathematics or quasi mathematics of algorithmic theory would be better studied using a more general machine intelligence kind of approach. The Hutter Solomonoff approach of Algorithmic Information Theory looks to me like it is too narrow and lacking a fundamental ground against which theories can be tested but I don't know for sure because I could never find a sound basis to use to study the theory. I just found a Ray Solomonoff's web site and he has a couple of links to lectures on it. http://www.idsia.ch/~juergen/ray.html Jim Bromer ------------------------------------------- agi Archives: https://www.listbox.com/member/archive/303/=now RSS Feed: https://www.listbox.com/member/archive/rss/303/ Modify Your Subscription: https://www.listbox.com/member/?member_id=8660244&id_secret=111637683-c8fa51 Powered by Listbox: http://www.listbox.com
