Collective Motion in a Network of Self-Propelled Agent Systems - Fig 1

<p>In system A, the position of node <i>w</i> is (<i>x</i>_{<i>A</i>,<i>w</i>},<i>y</i>_{<i>A</i>,<i>w</i>}), and it has 7 neighboring agents within a circle with a radius being <i>R</i> [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0144153#pone.0144153.e004" target="_blank">Eq (3)</a>], whose position projecting on system B is also (<i>x</i>_{<i>A</i>,<i>w</i>},<i>y</i>_{<i>A</i>,<i>w</i>}), and it has 4 neighboring agents in system B [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0144153#pone.0144153.e005" target="_blank">Eq (4)</a>]. Accordingly, we could identify the neighborhoods of all nodes in both systems.
