“…Lévy flight uses short‐distance search and occasional long‐distance walking alternately; this expands the search scope and increases the population diversity, thus avoiding local optima. The jumping path step length of Lévy flight is as follows: where α is a weighting factor, γ and ξ are random numbers following a normal distribution as shown in Equation (9), σ γ and σ ξ are the corresponding SDs, as shown in Equation (10), β is a parameter of the probability density function of the Lévy distribution, with β ∈ [0, 2], and Γ( x ) is the standard Gamma distribution function.…”
