We consider the following Problem:

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

Certificate: TIMEOUT

Proof:
  Computation stopped due to timeout after 60.0 seconds.
