Inverting Rayleigh wave dispersion curves to obtain S-wave velocity profiles is one of the most important steps in near-surface Rayleigh wave exploration. Rayleigh wave inversion is a multi-extremum. nonlinear problem. and this paper introduces the antlion optimizer to solve this type of problem. https://www.alarecre.com/NHL-Dallas-Stars-Black-Background-iPhone-13-Pro-Max-MagSafe-Case-p96318/
