Variational Iteration Method for Logistic Equation with Piecewise Constant Arguments

摘要

In this paper, variational iteration method is applied for finding the analytic approximate solution of Logistic equation with piecewise constant arguments. A correction functional is constructed by a general Lagrange multiplier, which can be identified by variational theory. Moreover, the iteration formula is obtained. The flexibility and adaptation provided by this method have been verified by an intuitive numerical example.
