We report a recent extension of a variationally optimized perturbation method, combining it with renormalization group properties in a straightforward way. This can provide a series of approximations to nonperturbative quantities such as the chiral symmetry breaking order parameters typically. It is

A new scenario in the renormalization group symmetry method is introduced to solve an initial value problem for a system of partial differential equations. As a specific example, we give an exact solution to the shallow water equations, which describes two-dimensional flow over a flat bottom.
