Keywords:
Nonlinear evolution equations, Solitary wave solutions,
Dependent variable, independent variable, Computer Algebra.
Programming language used: Maple V R4
Computer:
PC Pentium IV .
Nature of physical problem:
The program gives out exact solitary wave solutions, which can describe
various phenomena in nature, and thus can give more insight into the
physical aspects of problems and may be easily used in further
applications.
Restrictions:
The program can handle coupled nonlinear evolution equations in which
every equation is a polynomial (or can be converted to a polynomial) in
the unknown functions and their derivatives.
Typical running time:
It depends on the input equations as well as the degrees of the desired
polynomial solutions. For most of the coupled equations which we have
computed, the running time is no more than 20 seconds.
