Problem Zantema 05 jw09

Tool Bounds

Execution Time	3.2194853e-2ms
Answer	YES(?,O(n^1))
Input	Zantema 05 jw09

stdout:

YES(?,O(n^1))

We consider the following Problem:

  Strict Trs:
    {f(a(), f(a(), x)) -> f(x, f(a(), f(f(a(), a()), a())))}
  StartTerms: all
  Strategy: none

Certificate: YES(?,O(n^1))

Proof:
  The problem is match-bounded by 1.
  The enriched problem is compatible with the following automaton:
  {  a_0() -> 1
   , a_1() -> 4
   , a_1() -> 7
   , a_1() -> 8
   , a_1() -> 9
   , f_0(1, 1) -> 2
   , f_0(1, 2) -> 2
   , f_0(2, 1) -> 2
   , f_0(2, 2) -> 2
   , f_1(1, 3) -> 2
   , f_1(2, 3) -> 2
   , f_1(3, 3) -> 2
   , f_1(4, 5) -> 3
   , f_1(5, 3) -> 2
   , f_1(6, 7) -> 5
   , f_1(8, 9) -> 6}

Hurray, we answered YES(?,O(n^1))
