Abstract

The Parameter OptimizationMethod was presented with analytical and numerical examples. It was shown that it is a useful tool for solving differential equations with contour conditions. The numerical procedure is based only on Runge-Kutta integration routine and on optimization techniques, both frequently used and with many developed routines, thus it was shown that this approach is accessible and practical. The method was used to solve a one-dimensional Nonlinear Schr¨odinger Equation and a nonlinear Euler- Bernoulli beam.
