(10) UsableRulesProof (EQUIVALENT transformation)

For (infinitary) constructor rewriting [LOPSTR] we can delete all non-usable rules from R.

(11) Obligation:

Pi DP problem:
The TRS P consists of the following rules:

GT97_IN_AA(s(T370), s(T371)) → GT97_IN_AA(T370, T371)

R is empty.
The argument filtering Pi contains the following mapping:
s(x1)  =  s(x1)
GT97_IN_AA(x1, x2)  =  GT97_IN_AA

We have to consider all (P,R,Pi)-chains

(12) PiDPToQDPProof (SOUND transformation)

Transforming (infinitary) constructor rewriting Pi-DP problem [LOPSTR] into ordinary QDP problem [LPAR04] by application of Pi.

(13) Obligation:

Q DP problem:
The TRS P consists of the following rules:

GT97_IN_AA → GT97_IN_AA

R is empty.
Q is empty.
We have to consider all (P,Q,R)-chains.

(14) NonTerminationProof (EQUIVALENT transformation)

We used the non-termination processor [FROCOS05] to show that the DP problem is infinite.
Found a loop by semiunifying a rule from P directly.

s = GT97_IN_AA evaluates to t =GT97_IN_AA

Thus s starts an infinite chain as s semiunifies with t with the following substitutions:

• Matcher: [ ]
• Semiunifier: [ ]

---

Rewriting sequence

The DP semiunifies directly so there is only one rewrite step from GT97_IN_AA to GT97_IN_AA.

Pi DP problem:
The TRS P consists of the following rules:

GT97_IN_GA(s(T370), s(T371)) → GT97_IN_GA(T370, T371)

R is empty.
The argument filtering Pi contains the following mapping:
s(x1)  =  s(x1)
GT97_IN_GA(x1, x2)  =  GT97_IN_GA(x1)

We have to consider all (P,R,Pi)-chains

(21) QDPSizeChangeProof (EQUIVALENT transformation)

By using the subterm criterion [SUBTERM_CRITERION] together with the size-change analysis [AAECC05] we have proven that there are no infinite chains for this DP problem.

From the DPs we obtained the following set of size-change graphs:

• GT97_IN_GA(s(T370)) → GT97_IN_GA(T370)
  The graph contains the following edges 1 > 1

(22) YES

(24) UsableRulesProof (EQUIVALENT transformation)

For (infinitary) constructor rewriting [LOPSTR] we can delete all non-usable rules from R.

(25) Obligation:

Pi DP problem:
The TRS P consists of the following rules:

LE69_IN_GA(s(T270), s(T271)) → LE69_IN_GA(T270, T271)

R is empty.
The argument filtering Pi contains the following mapping:
s(x1)  =  s(x1)
LE69_IN_GA(x1, x2)  =  LE69_IN_GA(x1)

We have to consider all (P,R,Pi)-chains

(26) PiDPToQDPProof (SOUND transformation)

Transforming (infinitary) constructor rewriting Pi-DP problem [LOPSTR] into ordinary QDP problem [LPAR04] by application of Pi.

(27) Obligation:

Q DP problem:
The TRS P consists of the following rules:

LE69_IN_GA(s(T270)) → LE69_IN_GA(T270)

R is empty.
Q is empty.
We have to consider all (P,Q,R)-chains.

(28) QDPSizeChangeProof (EQUIVALENT transformation)

By using the subterm criterion [SUBTERM_CRITERION] together with the size-change analysis [AAECC05] we have proven that there are no infinite chains for this DP problem.

From the DPs we obtained the following set of size-change graphs:

• LE69_IN_GA(s(T270)) → LE69_IN_GA(T270)
  The graph contains the following edges 1 > 1

(29) YES

(31) UsableRulesProof (EQUIVALENT transformation)

For (infinitary) constructor rewriting [LOPSTR] we can delete all non-usable rules from R.

(32) Obligation:

Pi DP problem:
The TRS P consists of the following rules:

GT97_IN_AG(s(T370), s(T371)) → GT97_IN_AG(T370, T371)

R is empty.
The argument filtering Pi contains the following mapping:
s(x1)  =  s(x1)
GT97_IN_AG(x1, x2)  =  GT97_IN_AG(x2)

We have to consider all (P,R,Pi)-chains

(33) PiDPToQDPProof (SOUND transformation)

Transforming (infinitary) constructor rewriting Pi-DP problem [LOPSTR] into ordinary QDP problem [LPAR04] by application of Pi.

(34) Obligation:

Q DP problem:
The TRS P consists of the following rules:

GT97_IN_AG(s(T371)) → GT97_IN_AG(T371)

R is empty.
Q is empty.
We have to consider all (P,Q,R)-chains.

(35) QDPSizeChangeProof (EQUIVALENT transformation)

By using the subterm criterion [SUBTERM_CRITERION] together with the size-change analysis [AAECC05] we have proven that there are no infinite chains for this DP problem.

From the DPs we obtained the following set of size-change graphs:

• GT97_IN_AG(s(T371)) → GT97_IN_AG(T371)
  The graph contains the following edges 1 > 1

(36) YES

Q DP problem:
The TRS P consists of the following rules:

U18_AGAAAA(0, le69_out_ag(0)) → P67_IN_AGAAAA(0)
P67_IN_AGAAAA(0) → U18_AGAAAA(0, le69_out_ag(0))

The TRS R consists of the following rules:

le69_in_ag(s(T271)) → U15_ag(le69_in_ag(T271))
le69_in_ag(s(0)) → le69_out_ag(0)
le69_in_ag(0) → le69_out_ag(0)
gt97_in_ag(s(T371)) → U22_ag(gt97_in_ag(T371))
gt97_in_ag(0) → gt97_out_ag(s(0))
le69_in_ga(s(T270)) → U15_ga(le69_in_ga(T270))
le69_in_ga(0) → le69_out_ga(s(0))
le69_in_ga(0) → le69_out_ga(0)
gt97_in_ga(s(T370)) → U22_ga(gt97_in_ga(T370))
gt97_in_ga(s(0)) → gt97_out_ga(0)
U15_ag(le69_out_ag(T270)) → le69_out_ag(s(T270))

U22_ga(gt97_out_ga(T371)) → gt97_out_ga(s(T371))

The set Q consists of the following terms:

le69_in_ag(x0)
gt97_in_ag(x0)
le69_in_ga(x0)
gt97_in_ga(x0)
U15_ag(x0)

U22_ga(x0)

We have to consider all (P,Q,R)-chains.

(88) UsableRulesProof (EQUIVALENT transformation)

As all Q-normal forms are R-normal forms we are in the innermost case. Hence, by the usable rules processor [LPAR04] we can delete all non-usable rules [FROCOS05] from R.

Q DP problem:
The TRS P consists of the following rules:

U18_AGAAAA(0, le69_out_ag(0)) → P67_IN_AGAAAA(0)
P67_IN_AGAAAA(0) → U18_AGAAAA(0, le69_out_ag(0))

R is empty.
The set Q consists of the following terms:

le69_in_ag(x0)

gt97_in_ga(x0)
U15_ag(x0)

We have to consider all (P,Q,R)-chains.

(90) QReductionProof (EQUIVALENT transformation)

We deleted the following terms from Q as each root-symbol of these terms does neither occur in P nor in R.[THIEMANN].

le69_in_ag(x0)

P67_IN_AGAAAA(0) → U18_AGAAAA(0, le69_out_ag(0))

R is empty.
Q is empty.
We have to consider all (P,Q,R)-chains.

(92) NonTerminationProof (EQUIVALENT transformation)

We used the non-termination processor [FROCOS05] to show that the DP problem is infinite.
Found a loop by narrowing to the left:

s = P67_IN_AGAAAA(0) evaluates to t =P67_IN_AGAAAA(0)

Thus s starts an infinite chain as s semiunifies with t with the following substitutions:

• Semiunifier: [ ]
• Matcher: [ ]

---

Rewriting sequence

P67_IN_AGAAAA(0) → U18_AGAAAA(0, le69_out_ag(0))
with rule P67_IN_AGAAAA(0) → U18_AGAAAA(0, le69_out_ag(0)) at position [] and matcher [ ]

U18_AGAAAA(0, le69_out_ag(0)) → P67_IN_AGAAAA(0)
with rule U18_AGAAAA(0, le69_out_ag(0)) → P67_IN_AGAAAA(0)

Now applying the matcher to the start term leads to a term which is equal to the last term in the rewriting sequence


All these steps are and every following step will be a correct step w.r.t to Q.

(107) NonTerminationProof (EQUIVALENT transformation)

We used the non-termination processor [FROCOS05] to show that the DP problem is infinite.
Found a loop by narrowing to the left:

s = P67_IN_AGAAAA(s(0)) evaluates to t =P67_IN_AGAAAA(s(0))

Thus s starts an infinite chain as s semiunifies with t with the following substitutions:

• Semiunifier: [ ]
• Matcher: [ ]

---

Rewriting sequence

P67_IN_AGAAAA(s(0)) → U18_AGAAAA(s(0), le69_out_ag(0))
with rule P67_IN_AGAAAA(s(0)) → U18_AGAAAA(s(0), le69_out_ag(0)) at position [] and matcher [ ]

U18_AGAAAA(s(0), le69_out_ag(0)) → P67_IN_AGAAAA(s(0))
with rule U18_AGAAAA(s(z0), le69_out_ag(x1)) → P67_IN_AGAAAA(s(z0))

Now applying the matcher to the start term leads to a term which is equal to the last term in the rewriting sequence


All these steps are and every following step will be a correct step w.r.t to Q.

(110) UsableRulesProof (EQUIVALENT transformation)

For (infinitary) constructor rewriting [LOPSTR] we can delete all non-usable rules from R.

(111) Obligation:

Pi DP problem:
The TRS P consists of the following rules:

LE69_IN_AA(s(T270), s(T271)) → LE69_IN_AA(T270, T271)

R is empty.
The argument filtering Pi contains the following mapping:
s(x1)  =  s(x1)
LE69_IN_AA(x1, x2)  =  LE69_IN_AA

We have to consider all (P,R,Pi)-chains

(112) PiDPToQDPProof (SOUND transformation)

Transforming (infinitary) constructor rewriting Pi-DP problem [LOPSTR] into ordinary QDP problem [LPAR04] by application of Pi.

(113) Obligation:

Q DP problem:
The TRS P consists of the following rules:

LE69_IN_AA → LE69_IN_AA

R is empty.
Q is empty.
We have to consider all (P,Q,R)-chains.

(114) NonTerminationProof (EQUIVALENT transformation)

We used the non-termination processor [FROCOS05] to show that the DP problem is infinite.
Found a loop by semiunifying a rule from P directly.

s = LE69_IN_AA evaluates to t =LE69_IN_AA

Thus s starts an infinite chain as s semiunifies with t with the following substitutions:

• Matcher: [ ]
• Semiunifier: [ ]

---

Rewriting sequence

The DP semiunifies directly so there is only one rewrite step from LE69_IN_AA to LE69_IN_AA.

We have to consider all (P,Q,R)-chains.

(140) QDPOrderProof (EQUIVALENT transformation)

We use the reduction pair processor [LPAR04].

The following pairs can be oriented strictly and are deleted.

U6_GAA(split17_out_ggaaa(T156, T157)) → U7_GAA(T157, mergesort33_in_gaa(T156))
U6_GAA(split17_out_ggaaa(T156, T157)) → MERGESORT33_IN_GAA(T156)

The remaining pairs can at least be oriented weakly.

We use the reduction pair processor [LPAR04].

The following pairs can be oriented strictly and are deleted.

U10_GAA(T157, mergesort33_out_gaa) → MERGESORT33_IN_GAA(T157)

The remaining pairs can at least be oriented weakly.

(172) UsableRulesProof (EQUIVALENT transformation)

For (infinitary) constructor rewriting [LOPSTR] we can delete all non-usable rules from R.

(173) Obligation:

Pi DP problem:
The TRS P consists of the following rules:

GT97_IN_AA(s(T370), s(T371)) → GT97_IN_AA(T370, T371)

R is empty.
The argument filtering Pi contains the following mapping:
s(x1)  =  s(x1)
GT97_IN_AA(x1, x2)  =  GT97_IN_AA

We have to consider all (P,R,Pi)-chains

(174) PiDPToQDPProof (SOUND transformation)

Transforming (infinitary) constructor rewriting Pi-DP problem [LOPSTR] into ordinary QDP problem [LPAR04] by application of Pi.

(175) Obligation:

Q DP problem:
The TRS P consists of the following rules:

GT97_IN_AA → GT97_IN_AA

R is empty.
Q is empty.
We have to consider all (P,Q,R)-chains.

(176) NonTerminationProof (EQUIVALENT transformation)

We used the non-termination processor [FROCOS05] to show that the DP problem is infinite.
Found a loop by semiunifying a rule from P directly.

s = GT97_IN_AA evaluates to t =GT97_IN_AA

Thus s starts an infinite chain as s semiunifies with t with the following substitutions:

• Matcher: [ ]
• Semiunifier: [ ]

---

Rewriting sequence

The DP semiunifies directly so there is only one rewrite step from GT97_IN_AA to GT97_IN_AA.

(183) QDPSizeChangeProof (EQUIVALENT transformation)

By using the subterm criterion [SUBTERM_CRITERION] together with the size-change analysis [AAECC05] we have proven that there are no infinite chains for this DP problem.

From the DPs we obtained the following set of size-change graphs:

• GT97_IN_GA(s(T370)) → GT97_IN_GA(T370)
  The graph contains the following edges 1 > 1

(184) YES

We have to consider all (P,Q,R)-chains.

(190) QDPSizeChangeProof (EQUIVALENT transformation)

By using the subterm criterion [SUBTERM_CRITERION] together with the size-change analysis [AAECC05] we have proven that there are no infinite chains for this DP problem.

From the DPs we obtained the following set of size-change graphs:

• LE69_IN_GA(s(T270)) → LE69_IN_GA(T270)
  The graph contains the following edges 1 > 1

(191) YES

(197) QDPSizeChangeProof (EQUIVALENT transformation)

By using the subterm criterion [SUBTERM_CRITERION] together with the size-change analysis [AAECC05] we have proven that there are no infinite chains for this DP problem.

From the DPs we obtained the following set of size-change graphs:

• GT97_IN_AG(s(T371)) → GT97_IN_AG(T371)
  The graph contains the following edges 1 > 1

(198) YES

We have to consider all (P,Q,R)-chains.

(204) QDPSizeChangeProof (EQUIVALENT transformation)

By using the subterm criterion [SUBTERM_CRITERION] together with the size-change analysis [AAECC05] we have proven that there are no infinite chains for this DP problem.

From the DPs we obtained the following set of size-change graphs:

• LE69_IN_AG(s(T271)) → LE69_IN_AG(T271)
  The graph contains the following edges 1 > 1

(205) YES

We have to consider all (P,Q,R)-chains.

(270) NonTerminationProof (EQUIVALENT transformation)

We used the non-termination processor [FROCOS05] to show that the DP problem is infinite.
Found a loop by narrowing to the left:

s = P67_IN_AGAAAA(s(0)) evaluates to t =P67_IN_AGAAAA(s(0))

Thus s starts an infinite chain as s semiunifies with t with the following substitutions:

• Semiunifier: [ ]
• Matcher: [ ]

---

Rewriting sequence

P67_IN_AGAAAA(s(0)) → U18_AGAAAA(s(0), le69_out_ag(0, s(0)))
with rule P67_IN_AGAAAA(s(0)) → U18_AGAAAA(s(0), le69_out_ag(0, s(0))) at position [] and matcher [ ]

U18_AGAAAA(s(0), le69_out_ag(0, s(0))) → P67_IN_AGAAAA(s(0))
with rule U18_AGAAAA(s(z0), le69_out_ag(x1, s(z0))) → P67_IN_AGAAAA(s(z0))

Now applying the matcher to the start term leads to a term which is equal to the last term in the rewriting sequence

(280) UsableRulesProof (EQUIVALENT transformation)

For (infinitary) constructor rewriting [LOPSTR] we can delete all non-usable rules from R.

(281) Obligation:

Pi DP problem:
The TRS P consists of the following rules:

LE69_IN_AA(s(T270), s(T271)) → LE69_IN_AA(T270, T271)

R is empty.
The argument filtering Pi contains the following mapping:
s(x1)  =  s(x1)
LE69_IN_AA(x1, x2)  =  LE69_IN_AA

We have to consider all (P,R,Pi)-chains

(282) PiDPToQDPProof (SOUND transformation)

Transforming (infinitary) constructor rewriting Pi-DP problem [LOPSTR] into ordinary QDP problem [LPAR04] by application of Pi.

(283) Obligation:

Q DP problem:
The TRS P consists of the following rules:

LE69_IN_AA → LE69_IN_AA

R is empty.
Q is empty.
We have to consider all (P,Q,R)-chains.

(284) NonTerminationProof (EQUIVALENT transformation)

We used the non-termination processor [FROCOS05] to show that the DP problem is infinite.
Found a loop by semiunifying a rule from P directly.

s = LE69_IN_AA evaluates to t =LE69_IN_AA

Thus s starts an infinite chain as s semiunifies with t with the following substitutions:

• Matcher: [ ]
• Semiunifier: [ ]

---

Rewriting sequence

The DP semiunifies directly so there is only one rewrite step from LE69_IN_AA to LE69_IN_AA.

(285) NO

The TRS R consists of the following rules:

split21_in_gaaa([]) → split21_out_gaaa([], [], [])
split21_in_gaaa(.(T92, T93)) → U1_gaaa(T92, T93, split21_in_gaaa(T93))

U1_gaaa(T92, T93, split21_out_gaaa(T93, X163, X162)) → split21_out_gaaa(.(T92, T93), .(T92, X162), X163)

The set Q consists of the following terms:

U2_ggaaa(x0, x1, x2)
split21_in_gaaa(x0)
U1_gaaa(x0, x1, x2)

We have to consider all (P,Q,R)-chains.

(329) QDPOrderProof (EQUIVALENT transformation)

We use the reduction pair processor [LPAR04].

The following pairs can be oriented strictly and are deleted.

U30_GAA(T43, T44, T45, split17_out_ggaaa(T44, T45, T55, T56)) → MERGESORT1_IN_GAA(.(T43, T56))
U32_GAA(T43, T44, T45, split17_out_ggaaa(T44, T45, T55, T56)) → MERGESORT1_IN_GAA(.(T43, T56))
MERGESORT1_IN_GAA(.(T43, .(T44, T45))) → U35_GAA(T43, T44, T45, U2_ggaaa(T44, T45, split21_in_gaaa(T45)))

The remaining pairs can at least be oriented weakly.
Used ordering: Polynomial Order [NEGPOLO,POLO] with Interpretation:

POL( U2_ggaaa(x₁, ..., x₃) ) = x₃ + 2

POL( U30_GAA(x₁, ..., x₄) ) = x₄ + 1

POL( U32_GAA(x₁, ..., x₄) ) = x₄ + 1

POL( U35_GAA(x₁, ..., x₄) ) = x₄

POL( split21_in_gaaa(x₁) ) = x₁

POL( [] ) = 0

POL( split21_out_gaaa(x₁, ..., x₃) ) = x₂ + x₃

POL( .(x₁, x₂) ) = x₂ + 1

POL( U1_gaaa(x₁, ..., x₃) ) = x₃ + 1

POL( split17_out_ggaaa(x₁, ..., x₄) ) = x₄ + 2

POL( MERGESORT1_IN_GAA(x₁) ) = x₁ + 1

The following usable rules [FROCOS05] were oriented:

split21_in_gaaa([]) → split21_out_gaaa([], [], [])
split21_in_gaaa(.(T92, T93)) → U1_gaaa(T92, T93, split21_in_gaaa(T93))
U2_ggaaa(T72, T73, split21_out_gaaa(T73, X125, X124)) → split17_out_ggaaa(T72, T73, .(T72, X124), X125)
U1_gaaa(T92, T93, split21_out_gaaa(T93, X163, X162)) → split21_out_gaaa(.(T92, T93), .(T92, X162), X163)
