Lay out a set of agents where the agents repel each other and the links between them act like springs.

Lay out linked agents

End NetLogo code

Variants

All the text areas can be edited. If you want to limit the agents involved edit the first box. E.g. To only layout sheep replace it with all-of-kind "Sheep". To limit the layout to a subset of the links replace the contents of the second text area.

How this works

This uses the NetLogo layout-spring primitive to place the agents. It repeats calls to layout-spring since each time the constraints are solved bringing the configuration of agents closer to the ideal solution.

History

Lay out linked agents was implemented by Ken Kahn on 1 February 2011.
