InputZantema 04 z063

stdout:

YES(?,O(n^1))

We consider the following Problem:

  Strict Trs: {b(a(b(c(c(b(x1)))))) -> a(b(b(c(c(b(a(x1)))))))}
  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:
  {  b_0(1) -> 1
   , b_1(3) -> 2
   , b_1(4) -> 3
   , b_1(7) -> 6
   , c_0(1) -> 1
   , c_1(5) -> 4
   , c_1(6) -> 5
   , a_0(1) -> 1
   , a_1(1) -> 7
   , a_1(2) -> 1
   , a_1(2) -> 6}

Hurray, we answered YES(?,O(n^1))

stdout:

YES(?,O(n^1))

We consider the following Problem:

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

Certificate: YES(?,O(n^1))

Proof:
  We have the following triangular matrix interpretation:
  Interpretation Functions:
   b(x1) = [1 2 0] x1 + [0]
           [0 0 2]      [0]
           [0 0 0]      [2]
   c(x1) = [1 1 0] x1 + [0]
           [0 0 0]      [0]
           [0 0 0]      [0]
   a(x1) = [1 0 0] x1 + [0]
