Herself’s Artificial Intelligence

The zoologist and his colleagues discovered that when a swarm contains between 25 and 74 locusts per square metre, the locusts are almost always aligned but exhibit rapid and spontaneous changes in direction. There were almost no directional changes above that range of densities. [read more Sychronising the swarm]

So what does this mean for software and robotic swarms? Are there densities of particles in the swarm that will drastically change the behavior? Are swarm systems chaotic and if so what does that mean for designers of swarms? Many of the same simple rules we are using to program our swarms are based on insect swarms. So it isn’t a far reach to think that perhaps some of the odder previously thought to be unexplained behavior of insect swarms may show up in our software and our robot swarms at specific densities.

Swarms are being used in more real world applications. What happens if the swarm balancing network traffic on your server all aligns and sends all the traffic to one machine? Or more troubling what happens when US Military swarm based robots suddenly evolve new unexpected behaviors?

This is clearly an area that needs serious research in the very near future.

All is not bad, we can also use studies like this to predict crowd behavior in crowded situations using swarm models. Knowing at what crowd density the behavior changes can help us better design buildings and infrastructure preventing tragedies like the Rhode Island night club fire a few years back.
