Problem SK90 4.32

Tool Bounds

Execution Time	60.04172ms
Answer	TIMEOUT
Input	SK90 4.32

stdout:

TIMEOUT

We consider the following Problem:

  Strict Trs:
    {  c(w(x)) -> x
     , b(v(x)) -> x
     , a(u(x)) -> x
     , w(c(x)) -> x
     , v(b(x)) -> x
     , u(a(x)) -> x
     , c(a(x)) -> a(c(c(x)))
     , b(c(x)) -> c(b(b(x)))
     , a(b(x)) -> b(a(a(x)))}
  StartTerms: all
  Strategy: none

Certificate: TIMEOUT

Proof:
  Computation stopped due to timeout after 60.0 seconds.

Arrrr..
