Ameisen sind zu komplexen Problemlösungen fähig - und ihre Strategien könnten breite Anwendung in Optimierungstechniken finden. Eine einzelne Ameise wandert bei der Nahrungssuche nach dem Zufallsprinzip herum, wie Biologen feststellten. Im Kollektiv aber zeigen die Ameisen ein weit hierüber hinaus reichendes Verhalten, wie jetzt eine mathematische Studie in den Proceedings of the National Academy of Sciences zeigt: Ab einem bestimmten Punkt verändern sich die Bewegungsmuster der Tiere vom Chaos zur Ordnung. Dies geschieht überraschend wirkungsvoll durch Selbst-Organisation. Das Verhalten der Ameisen zu verstehen könnte helfen bei der Analyse ähnlicher Phänomene - etwa wie Menschen sich im Internet bewegen.
