Problem Zantema 04 z049

Tool Bounds

Execution Time	3.0895948e-2ms
Answer	YES(?,O(n^1))
Input	Zantema 04 z049

stdout:

YES(?,O(n^1))

We consider the following Problem:

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

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

TIMEOUT

We consider the following Problem:

  Strict Trs: {a(b(a(a(b(b(x1)))))) -> a(a(b(a(b(b(a(x1)))))))}

Tool TRI

Execution Time	13.061239ms
Answer	YES(?,O(n^2))
Input	Zantema 04 z049

stdout:

YES(?,O(n^2))

We consider the following Problem:

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

Certificate: YES(?,O(n^2))

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

Hurray, we answered YES(?,O(n^2))

Tool TRI2

Execution Time	1.240016ms
Answer	MAYBE
Input	Zantema 04 z049

stdout:

MAYBE

We consider the following Problem:

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

Certificate: MAYBE

Proof:
  The input cannot be shown compatible
