The idea is to use a classic swarm as a model for a religious or political movement (since the basic rules like global attraction and local repulsion are isomorphic, as I argue in earlier chapters). </div><div dir="auto"><br></div><div dir="auto">The new thing is an "oblivion" factor which causes agents to forget the classic Boids swarm rules step by step. In order to keep the swarm from dissolving the model reinforces the rules every T timesteps, which simulates a rally, convention or congregation for the movement. Therefore the name "Oblivion Resistant Swarm" (ORS model) :-)</div><div dir="auto"></div><div dir="auto"><br></div><div dir="auto">As T varies, I expect to find some kind of phase transition in simulations where the swarm forms or dissolves. If T is too large, the swarm forgets the rules and is unable to maintain the form. If T is very small we get the classic Boids model and the swarm is able to form. Does that make any sense? Two more questions:</div><div dir="auto"><br></div><div dir="auto">1. Is two weeks a reasonable timespan for the time we need to learn new rules in general? </div><div dir="auto"><br></div><div dir="auto">2. Do you know any existing ABMs which are similar? </div><div dir="auto"><br></div><div dir="auto">-J.</div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto"><br></div><div id="composer_signature" dir="auto"><div style="font-size:85%;color:#575757" dir="auto"><br></div></div><div dir="auto"><br></div></body></html>
