The agents can also ``remember'' and ``forget''. The memory size is decreased while the population size is kept constant. ``Fame'' emerged as a few agents become very well known in expense of the majority being completely forgotten. The minimum and the maximum of fame change linearly with the relative memory size. The network properties of the who-knows-who graph, which represents the state of the system, are investigated.7 pages, 5 figuresAdaptation and Self-Organizing SystemsComputers and SocietyMultiagent SystemsPhysics and Societytext
