Bat algorithm

Bat-inspired algorithm is a metaheuristic search optimization developed by Xin-She Yang in 2010.^[1] This bat algorithm is based on the echolocation behaviour of microbats with varying pulse emission and loudness.^[2]^[3]

Algorithm Description

The idealization of echolocation can be summarized as follows: Each virtual bat fly randomly with a velocity $v_{i}$ at position (solution) $x_{i}$ with a varying frequency or wavelength and loudness $A_{i}$ . As it searches and finds its prey, it changes frequency, loudness and pulse emission rate $r$ . Search is intensified by a local random walk. Selection of the best continues until certain stop criteria are met.

A detailed intrudction of metaheuristic algorithms including the bat algorithm is given by Yang ^[4] where a demo program in Matlab/Octave is available, while a comprehensive review is carried out by Parpinelli and Lopes.^[5]

Multi-objective Bat Algorithm (MOBA)

Using a simple weighted sum with random weights, a very effective but yet simple multiobjective bat algorithm (MOBA) has been developed to solve multiobjective engineering design tasks.^[6]

Applications

A fuzzy bat clustering method has been developed to solve ergonomic workplace problems^[7]
