![]() Then Li-Yorke algorithm is applied in solving initial value problems for differential equations to trace homotopy curves. A backcalculation model based on homotopy method is established by using a numerical differential method to solve the first and the second partial derivatives of deflections with respect to moduli. In accordance with the extreme value condition for optimization, the backcalculation of pavement layer moduli is converted into the solution of a zero point problem for nonlinear mapping.
