Problem SK90 4.43

Tool Bounds

Execution Time	60.101513ms
Answer	TIMEOUT
Input	SK90 4.43

stdout:

TIMEOUT

We consider the following Problem:

  Strict Trs:
    {  f(h(x, h(y, z))) -> f(h(+(x, y), z))
     , f(g(h(x, y))) -> f(h(s(x), y))
     , f(g(f(x))) -> f(h(s(0()), x))
     , +(x, +(y, z)) -> +(+(x, y), z)
     , +(s(x), y) -> s(+(x, y))
     , +(0(), y) -> y
     , +(x, s(y)) -> s(+(x, y))
     , +(x, 0()) -> x}
  StartTerms: all
  Strategy: none

Certificate: TIMEOUT

Proof:
  Computation stopped due to timeout after 60.0 seconds.
