Employing natural search strategies for complex optimization problems — Christoph Schiffmann and •Daniel Sebastiani — Freie Universität Berlin

The Artificial Bee Colony algorithm¹ is a stochastic optimization scheme that mimics the foraging behavior of honey bees. As one of the most recently developed “nature-inspired” algorithms, this approach has turned out to perform very efficiently in global optimization problems from engineering and computer science.

We apply the Artificial Bee Colony algorithm to optimization problems² in chemical physics, specifically within ab-initio electronic structure theory. This field is a case in point for highly corrugated potential surfaces which render deterministic approaches unfeasible.
