Re: [Swarm-Modelling] theroy behind the swarm simulation toolbox

[Jörg Kühne]

Many thanks Alex

Means that, the swarm simulation framework has nothing to do with a bionic 
approach to the behavior of a swarm as individuals. (especially animals with - 
for example herd instinct and even more)?

best regards

Joerg
