Tool Bounds

Execution Time	60.086754ms
Answer	TIMEOUT
Input	Zantema 05 z12

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

Certificate: TIMEOUT

Proof:
  Computation stopped due to timeout after 60.0 seconds.

Arrrr..

Answer	MAYBE
Input	Zantema 05 z12

stdout:

MAYBE

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

Certificate: MAYBE

Proof:
  The input cannot be shown compatible

Arrrr..
