review text: The method proposed here consists of the reformulation of the initial boundary value problem as a boundary value problem with one of the initial conditions redundant. By means of a direct method in which this redundant initial condition is used for the choice of the trial functions, an approximation is found to a function that renders the variational principle stationary.
