Australian Journal of Basic and Applied Sciences, Vol. 5 Apr., (2011) 60-66.

In this paper, a modification of He’s variational iteration method by using r terms of Taylor’s series is applied for finding the solution of Kolmogorov-Petrovskii-Piskunov and Klein-Gordon equations with logarithmic  non-linearities. This modification cause to the new application of the variational iteration method for equations with logarithmic nonlinear part. To show the efficiency of the method, several examples are presented.
