Yes, I agree depth to be a measure of one kind of time, ie how much parallel time (processing cycles) does something take vs. elapsed background "wallclock" time. Maybe Gus can jump in and layout ~7 or so common types of time so we can figure out which kind of time we're really talking about. And as West and Brown's quarter-power allometric scaling (metabolic/system rate scales at 3/4, duration at 1/4, and cellular/agent rate -1/4) all are a function of time, I suspect one could find similar scaling laws with depth as you increase the number of agents/mass in certain types of ABM eg ones that exhibit self-organization or move through phase-transitions. -Steve ============================================================ FRIAM Applied Complexity Group listserv Meets Fridays 9a-11:30 at cafe at St. John's College lectures, archives, unsubscribe, maps at http://www.friam.org
