Nature of problem:
Chaotic behaviour of solutions of a autonomous system is excluded if a first integral exists. So the existence of first integrals is fundamental for understanding the process described by a given system of ordinary differential equations.

Restrictions:
Depends heavily on the problem, predictions cannot be made.

Running time:
