Researchers have developed an adaptive ant colony system that combines four heuristic strategies, a roulette-based ranking ...

For the past three decades Deborah Gordon has devoted herself to studying ant colonies in the Arizona desert. Although her chosen subject – the red harvester ant – isn’t much to look at, when they ...

This chapter introduces ant colony optimization as a method for computing minimum Steiner trees in graphs. Tree computation is achieved when multiple ants, starting out from different nodes in the ...

New drugs often fail because they cause undesirable side effects. Researchers have now developed simulation software that predicts the properties of active agents and virtually builds new ones. The ...

An analysis of ant colony behavior could yield better algorithms for network communication, say investigators. Biologists have long suspected that ants base their population-density estimates on the ...

The biologist Deborah Gordon has uncovered how ant colonies search efficiently without central organization, an insight that might improve computer networks. Ants are capable of remarkable feats of ...
