WebNov 9, 2024 · Alternatively, the selection of the number of particles of the swarm population (\(n\)) depends on the objective function to optimize. Although the algorithm performance is not very sensitive to the size of the swarm (Wang et al. 2024), an insufficient number of particles may not converge to the optimum solution (Raß et al. 2015). WebTo confirm the natural behaviour of the AO strategy for different noise values, the performance of the AO method is also verified by fixing the population size (30, 40, or 50) and changing the generation size (1000, 1500, or 2000) for three values of noise variance (0.04, 0.06, and 0.08), and the fitness-based learning curves are presented in Figure 6.
