Abstract :
An improved algorithm that is used to alleviate the downsides of the whale optimization algorithm's (WOA)
drawbacks which are slow convergence rate and falling into local optima, is proposed. There are five main variables
introduced into this enhanced algorithm. These include the Cauchy density function, quasi-opposition-based learning,
Euclidean distance, cubic chaotic mapping, and weight addition. The proposed algorithm was compared to the original
WOA, two recent variants, and one other swarm-based intelligent algorithm, on twenty-three benchmark functions. The
parameters used for comparison were Optimal value, Mean, Standard Deviation, and convergence rate. The improved
WOA yields better optimal values with minimal iterations. The results validate that the Improved WOA outperforms the
other four algorithms.
