Nature of problem:
Find the symmetries of the given evolution equation: This is important because it enables us to know the qualitative nature of the equation and leads to physical insight.

The available computer storage is the severest restriction.

Running time:
It depends on the rank of the symmetry. It cannot be estimated in advance.
