Execution Time	60.034542ms
Answer	TIMEOUT
Input	Zantema 04 z083

stdout:

TIMEOUT

We consider the following Problem:

  Strict Trs:
    {  d(a(c(x1))) -> b(b(x1))
     , d(c(x1)) -> d(b(d(x1)))
     , d(c(x1)) -> b(d(x1))
     , b(b(b(x1))) -> a(b(c(x1)))
     , a(d(x1)) -> d(c(x1))
     , b(a(c(x1))) -> b(c(x1))
     , b(d(b(x1))) -> c(d(b(x1)))}
  StartTerms: all
  Strategy: none

Certificate: TIMEOUT

Proof:
  Computation stopped due to timeout after 60.0 seconds.

Arrrr..
