Boolean Binary Grey Wolf Optimizer [PDF]

, 2022
Several binary swarm algorithms use the identical continuous proposal, adding a transfer function to mapping from continuous to binary space. It has been shown that binary operators are more appropriate and efficient for binary optimisation. Based on it,

An Improved Grey Wolf Optimization Algorithm with Variable Weights

Computational Intelligence and Neuroscience, 2019
With a hypothesis that the social hierarchy of the grey wolves would be also followed in their searching positions, an improved grey wolf optimization (GWO) algorithm with variable weights (VW-GWO) is proposed. And to reduce the probability of being trapped in local optima, a new governing equation of the controlling parameter is also proposed ...
