stdout:

YES(?,O(n^3))

We consider the following Problem:

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

Certificate: YES(?,O(n^3))

Proof:
  We have the following EDA-non-satisfying matrix interpretation:
  Interpretation Functions:
   a(x1) = [1 1 0] x1 + [0]
           [0 0 0]      [0]
           [0 0 0]      [2]
   b(x1) = [1 0 0] x1 + [2]
           [0 0 2]      [0]
           [0 0 0]      [0]

Hurray, we answered YES(?,O(n^3))

  StartTerms: all
  Strategy: none

Certificate: YES(?,O(n^1))

Proof:
  We have the following EDA-non-satisfying and IDA(1)-non-satisfying matrix interpretation:
  Interpretation Functions:
