I read the article "ONEOptimal: A Maple Package for Generating One-Dimensional Optimal System of Finite Dimensional Lie Algebra", and also searched out in Maplesoft website, but couldn't found. Does anyone have the package?

I read the article "Approximate Symmetries and Infinite Series Symmetry Reduction Solutions to Perturbed Kuramoto–Sivashinsky Equation", and also searched out in Maplesoft website, but couldn't found. Does anyone have the package?

In the paper of Nail H. Ibragimov there is operator Euler-Lagrange operator. How I can use this operator in Maple to derive adjoint equations? I can your help. I need maple worksheet for this.

Hi, dear community,
I have a Maple package "rath" for finding the traveling wave solution of differential equations. But I am not able to loading in Maple 18. Please see this attached zip folder and need help in this regard.
