From: Quadrilateral mesh optimisation method based on swarm intelligence optimisation

Algorithm

Key parameters

Common parameters

Firefly algorithm

\(\gamma =1.0\) (light absorption), \(\alpha =0.1\) (randomness factor), \(\beta =0.5\) (attraction coefficient)

Population size = 50

Wolf pack algorithm

\(\alpha =4\) (scout ratio), \(T_{\max }=10\) (max walk steps), \(w=10\) (distance factor)

Max iterations = 200

 

\(S=20\) (step factor), \(\beta =5\) (update ratio)

 
 

\(h_{\max }=36\) (maximum walk depth), \(h_{\min }=12\) (minimum walk depth)

 

PSO algorithm

\(\omega =0.4\) (inertia weight), \(c_1=0.2\) (cognitive factor), \(c_2=0.4\) (social factor)
