Nature of problem:Lie symmetries of differential equations play an important role in all branches of physics. Usually they have a physical meaning. To know all Lie symmetries for a given problem is therefore of utmost importance because it usually leads to additional physical insight. | ||

Restrictions:In most cases the available computer memory is the severest restriction. It may only be avoided if the problem is split into several smaller ones. | ||

Running time:It depends heavily on the number of dependent and independent variables and the structure of the problem. It cannot be estimated in advance. |
