Ant colonies: Behavioral variability wins

Quoted from ScienceDaily: Top News:
They attack other colonies, plunder and rob, kill other colonies’ inhabitants or keep them as slaves: Ants are usually regarded as prototypes of social beings that are prepared to sacrifice their lives for their community, but they can also display extremely aggressive behavior towards other nests. Evolutionary biologists in Germany have found that ant colonies are more productive and raise more offspring when the workers in the colony display considerable variation in their levels of aggression. This variation in aggression is possibly part of their division of labor, which is regarded as the basis of the success of social insect […]

Ant colony optimization algorithms have been applied to many binatorial optimization problems, ranging from quadratic assignment to protein folding or routing vehicles and a lot of derived methods have been adapted to dynamic problems in Ant colonies don’t organize per se, but they still pull off plex behavior in harsh environments without any glitches. New research looks into how the insects manage this, offering inspiration Colonies Retain Memories That Outlast the Lifespans of Individuals An colony can thrive for decades, changing its behavior based on past events even as individual s die off every year or so Tags: colonies, retain, memories, that, The Behavior of Ants - The Behavior of s Machiko Osawa Among all species of insects, s are known for their earnest life style according to one story by Aesop, “The and the Grasshopper.” Each colony could be characterized by a type s along a docile-aggressive axis, with higher scoring colonies being more active, responsive, and aggressive than those with lower ss. Furthermore, colony types were correlated
