[FRIAM] stygmergy, CA's, and [biological] development

[Stephen Guerin]

Nick,

A reminder on Micheal Levin's work on regeneration, inheritance and
connection to bioelectric fields:

zoomed to experiment but I encourage you to watch the whole talk.

Stigmergy is coordination through indirect communication. Ant foraging,
termite nest construction and cellular slime mold aggregation and maze
solving are all good examples.

Agentscript examples:

I would argue Flocking/Schooling, by contrast, are not be stigmergic as the
boids detect their neighbor position and headings directly. Though don't
want to get into a DAWW contest :-)
