An accurate relationship between frequency and amplitude to nonlinear oscillations
A weighted global error minimization (WGEM) is proposed in this study. The goal is to improve the accuracy of the global error minimization (GEM) based on a weighting function. In addition to the first-order approximation, the fourth-order approximation for the Duffing oscillator is demonstrated by...
