Execution Time	60.042797ms
Answer	TIMEOUT
Input	Zantema 05 z13

stdout:

TIMEOUT

We consider the following Problem:

  Strict Trs:
    {  f(b(x), y) -> f(x, b(y))
     , f(a(x), y) -> f(x, a(y))
     , f(x, b(a(y))) -> f(b(b(x)), y)
     , f(x, a(b(y))) -> f(a(a(x)), y)}
  StartTerms: all
  Strategy: none

Certificate: TIMEOUT

Proof:
  Computation stopped due to timeout after 60.0 seconds.

Arrrr..
