AIXI is not a physically realizable system, it's just a hypothetical mathematical entity. It could never actually be built, in any universe. AIXItl is physically realizable in theory, but probably never in our universe... it would require too much computational resources. (Except for trivially small values of the parameters t and l, which would result in a very dumb AIXItl, i.e. probably dumber than a beetle.) The way they work is to generate all possible programs (AIXI) or all possible programs of a given length l (AIXItl). (It's easy to write a program that generates all possible programs, the problem is that it runs forever ;). -- Ben G ------- To unsubscribe, change your address, or temporarily deactivate your subscription, please go to http://v2.listbox.com/member/?[EMAIL PROTECTED]
