<div dir="ltr">I thought it worked well. I don't know what Ford did with it if anythinng. There was at least one person that claimed he could reach the same conclusions analytically. But he wouldn't have been able to model the social interaction of customers, the effects of advertising, and the effects of social media for instance. I'll bet there are Ford Ranger Facebook groups. Ford wanted the results in order to determine which option sets to manufacture. <div><br></div><div>Frank</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, Jun 6, 2020 at 2:12 PM Barry MacKichan <<a href="mailto:barry.mackichan@mackichan.com">barry.mackichan@mackichan.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><u></u>

<p class="MsoNormal">I would like to add an agent-based model for the last chapter of my book. 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). <u></u><u></u></p>
</div>
<div>
<p class="MsoNormal"><u></u> <u></u></p>
</div>
<div>
<p class="MsoNormal">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) :-)<u></u><u></u></p>
</div>
<div>
<p class="MsoNormal"><u></u> <u></u></p>
</div>
<div>
<p class="MsoNormal">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:<u></u><u></u></p>
</div>
<div>
<p class="MsoNormal"><u></u> <u></u></p>
</div>
<div>
<p class="MsoNormal">1. Is two weeks a reasonable timespan for the time we need to learn new rules in general? <u></u><u></u></p>
