Nature of problem:
Our program can perform the traditional Painlevé test for nonlinear partial differential equations automatically, and some truncated expansions are also obtained whether or not the given equations pass the test. The obtained truncated expansions play an important role in studying the integrability as well as constructing explicit exact solutions.
The program can handle coupled nonlinear partial differential equations, in which every equation is a polynomial (or can be converted to a polynomial) in the unknown functions and their derivatives.
It depends on the input equations, numbers of possible branches and the value of the largest resonance. For most of the nonlinear partial differential equations which we have tested, the running time is no more than 10 seconds.
