Tool Bounds

Execution Time	2.214694e-2ms
Answer	YES(?,O(n^1))
Input	Der95 03

stdout:

YES(?,O(n^1))

We consider the following Problem:

  Strict Trs: {f(f(x)) -> g(f(x))}
  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:
  {  f_0(1) -> 1
   , f_1(1) -> 2
   , g_0(1) -> 1
   , g_1(2) -> 1
   , g_1(2) -> 2}

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

QUADRATIC upper bound on the derivational complexity

This TRS is terminating using the deltarestricted interpretation
f(delta, X0) = + 0*X0 + 2 + 1*X0*delta + 0*delta
g(delta, X0) = + 1*X0 + 0 + 0*X0*delta + 0*delta
f_tau_1(delta) = delta/(0 + 1 * delta)
g_tau_1(delta) = delta/(1 + 0 * delta)
