【 摘 要 】

A tutorial review is presented of the use of direct variational methods based on RayleighRitz optimization for finding approximate solutions to various nonlinear evolution equations. The practical application of the approach is demonstrated by some illustrative examples in connection with the nonlinear Schrödinger equation.
