Richard, These last two messages with replies to Mark's questions clarify your position more clearly than much of your prior writing (although I didn't keep track of later discussions too closely). I think it's important to show in the same example all the controversial aspects: relatively simple rules, use cases where an aspect of global behavior can be modeled by a simple theory (two-body problem, F-14, most of the planets in short term, gliders in GoL), and use cases for the same global system where there is no simple model (n-body problem, Pluto, more general initial state in GoL).
But all the same, problems that you describe as complex are just numerical calculation problems. In the case of symbol interaction, initial conditions (rules) are unknown and results are discontinuous, which requires much methodical enumeration to find the rules that give required global behavior, no clever tricks work. -- Vladimir Nesov [EMAIL PROTECTED] ------------------------------------------- agi Archives: http://www.listbox.com/member/archive/303/=now RSS Feed: http://www.listbox.com/member/archive/rss/303/ Modify Your Subscription: http://www.listbox.com/member/?member_id=8660244&id_secret=101455710-f059c4 Powered by Listbox: http://www.listbox.com
