In this paper, the genetic algorithm is used as the optimization algorithm, and the simulated annealing algorithm is used as an extension. The cubic spline interpolation method is used to find the optimal solution. Witryna13 kwi 2024 · We conducted a sensitivity analysis on the population size and selected four different population sizes, namely 10, 15, 20, and 30, to find the optimal population size. As shown in Table 3 and Figure 9 , when the population size was set to 20, the convergence speed of WOA was faster, and it had the best performance evaluation … can\u0027t bear the thought
