Computer:
PC Pentium III .
Nature of physical problem:
A Maple package RATH which outputs entirely automatically
tanh-polynomial travelling solitary wave solutions of a given nonlinear
evolution equation is presented. The effectiveness of RATH is
demonstrated by applications to a variety of equations with physical
interest as examples. Not only are previously known solutions recovered
but in some cases new solutions and more general form of solutions are
obtained.
