An Algorithm for Global Optimization Inspired by Collective Animal Behavior

Abstract EN

A metaheuristic algorithm for global optimization called the collective animal behavior (CAB) is introduced.

Animal groups, such as schools of fish, flocks of birds, swarms of locusts, and herds of wildebeest, exhibit a variety of behaviors including swarming about a food source, milling around a central locations, or migrating over large distances in aligned groups.

These collective behaviors are often advantageous to groups, allowing them to increase their harvesting efficiency, to follow better migration routes, to improve their aerodynamic, and to avoid predation.

In the proposed algorithm, the searcher agents emulate a group of animals which interact with each other based on the biological laws of collective motion.

The proposed method has been compared to other well-known optimization algorithms.

The results show good performance of the proposed method when searching for a global optimum of several benchmark functions.
