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 rates of emission and loudness.[2][3]

Algorithm Description
The idealization of the [echolocation]] of microbats can be summarized as follows: Each virtual bat flies randomly with a velocity 
at position (solution) 
with a varying frequency or wavelength and loudness 
. As it searches and finds its prey, it changes frequency, loudness and pulse emission rate 
. Search is intensified by a local random walk. Selection of the best continues until certain stop criteria are met.
A detailed introduction 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] A further improvement is the development of an evolving bat algorithm (EBA) with better efficiency.[6]
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.[7] Another multiobjective bat algorithm by combining bat algorithm with NSGA-II produces very competitive results with good efficiency.[8]
Applications
A fuzzy bat clustering method has been developed to solve ergonomic workplace problems[9]
