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

IF1(true, s(x0), s(x1)) → IF2(div(x0, x1, s(x1)), s(x0), s(x1))
TEST(s(x0), s(x1)) → IF1(gt(x0, x1), s(x0), s(x1))
IF2(false, s(z0), s(z1)) → TEST(s(z0), s(s(z1)))

The TRS R consists of the following rules:

gt(s(x), 0) → true
gt(0, y) → false
gt(s(x), s(y)) → gt(x, y)
div(0, 0, z) → true
div(0, s(x), z) → false
div(s(x), 0, s(z)) → div(s(x), s(z), s(z))
div(s(x), s(y), z) → div(x, y, z)

The set Q consists of the following terms:

gt(s(x0), 0)
gt(0, x0)
gt(s(x0), s(x1))
div(0, 0, x0)
div(0, s(x0), x1)
div(s(x0), 0, s(x1))
div(s(x0), s(x1), x2)

We have to consider all minimal (P,Q,R)-chains.
By instantiating [15] the rule TEST(s(x0), s(x1)) → IF1(gt(x0, x1), s(x0), s(x1)) we obtained the following new rules:

TEST(s(z0), s(s(z1))) → IF1(gt(z0, s(z1)), s(z0), s(s(z1)))

By instantiating [15] the rule IF1(true, s(z0), s(s(z1))) → IF2(div(z0, s(z1), s(s(z1))), s(z0), s(s(z1))) we obtained the following new rules:

IF1(true, s(z0), s(s(s(z1)))) → IF2(div(z0, s(s(z1)), s(s(s(z1)))), s(z0), s(s(s(z1))))

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

IF2(false, s(z0), s(s(z1))) → TEST(s(z0), s(s(s(z1))))
IF1(true, s(z0), s(s(s(z1)))) → IF2(div(z0, s(s(z1)), s(s(s(z1)))), s(z0), s(s(s(z1))))
TEST(s(z0), s(s(s(z1)))) → IF1(gt(z0, s(s(z1))), s(z0), s(s(s(z1))))

The TRS R consists of the following rules:

gt(s(x), 0) → true
gt(0, y) → false
gt(s(x), s(y)) → gt(x, y)
div(0, 0, z) → true
div(0, s(x), z) → false
div(s(x), 0, s(z)) → div(s(x), s(z), s(z))
div(s(x), s(y), z) → div(x, y, z)

The set Q consists of the following terms:

gt(s(x0), 0)
gt(0, x0)
gt(s(x0), s(x1))
div(0, 0, x0)
div(0, s(x0), x1)
div(s(x0), 0, s(x1))
div(s(x0), s(x1), x2)

We have to consider all minimal (P,Q,R)-chains.
The DP Problem is simplified using the Induction Calculus [18] with the following steps:
Note that final constraints are written in bold face.

For Pair IF2(false, s(z0), s(s(z1))) → TEST(s(z0), s(s(s(z1)))) the following chains were created:

We consider the chain IF2(false, s(z0), s(s(z1))) → TEST(s(z0), s(s(s(z1)))), TEST(s(z0), s(s(s(z1)))) → IF1(gt(z0, s(s(z1))), s(z0), s(s(s(z1)))) which results in the following constraint:
(1) (TEST(s(x2), s(s(s(x3))))=TEST(s(x4), s(s(s(x5)))) ⇒ IF2(false, s(x2), s(s(x3)))≥TEST(s(x2), s(s(s(x3)))))

We simplified constraint (1) using rules (I), (II), (IV) which results in the following new constraint:
(2) (IF2(false, s(x2), s(s(x3)))≥TEST(s(x2), s(s(s(x3)))))

For Pair TEST(s(z0), s(s(s(z1)))) → IF1(gt(z0, s(s(z1))), s(z0), s(s(s(z1)))) the following chains were created:

We consider the chain TEST(s(z0), s(s(s(z1)))) → IF1(gt(z0, s(s(z1))), s(z0), s(s(s(z1)))), IF1(true, s(z0), s(s(s(z1)))) → IF2(div(z0, s(s(z1)), s(s(s(z1)))), s(z0), s(s(s(z1)))) which results in the following constraint:
(3)    (IF1(gt(x12, s(s(x13))), s(x12), s(s(s(x13))))=IF1(true, s(x14), s(s(s(x15)))) ⇒ TEST(s(x12), s(s(s(x13))))≥IF1(gt(x12, s(s(x13))), s(x12), s(s(s(x13)))))

We simplified constraint (3) using rules (I), (II), (IV), (VII) which results in the following new constraint:

We simplified constraint (4) using rule (V) (with possible (I) afterwards) using induction on gt(x12, x24)=true which results in the following new constraints:
(5)    (true=true∧s(s(x13))=0 ⇒ TEST(s(s(x25)), s(s(s(x13))))≥IF1(gt(s(x25), s(s(x13))), s(s(x25)), s(s(s(x13)))))

(6)    (gt(x27, x28)=true∧s(s(x13))=s(x28)∧(∀x29:gt(x27, x28)=true∧s(s(x29))=x28 ⇒ TEST(s(x27), s(s(s(x29))))≥IF1(gt(x27, s(s(x29))), s(x27), s(s(s(x29))))) ⇒ TEST(s(s(x27)), s(s(s(x13))))≥IF1(gt(s(x27), s(s(x13))), s(s(x27)), s(s(s(x13)))))

We solved constraint (5) using rules (I), (II).We simplified constraint (6) using rules (I), (II), (IV) which results in the following new constraint:
(7)    (gt(x27, x28)=true∧s(x13)=x28 ⇒ TEST(s(s(x27)), s(s(s(x13))))≥IF1(gt(s(x27), s(s(x13))), s(s(x27)), s(s(s(x13)))))

We simplified constraint (7) using rule (V) (with possible (I) afterwards) using induction on gt(x27, x28)=true which results in the following new constraints:
(8)    (true=true∧s(x13)=0 ⇒ TEST(s(s(s(x30))), s(s(s(x13))))≥IF1(gt(s(s(x30)), s(s(x13))), s(s(s(x30))), s(s(s(x13)))))

We simplified constraint (11) using rules (I), (II) which results in the following new constraint:

We simplified constraint (12) using rule (VI) where we applied the induction hypothesis (gt(x37, x38)=true ⇒ TEST(s(s(s(x37))), s(s(s(x38))))≥IF1(gt(s(s(x37)), s(s(x38))), s(s(s(x37))), s(s(s(x38))))) with σ = [ ] which results in the following new constraint:

For Pair IF1(true, s(z0), s(s(s(z1)))) → IF2(div(z0, s(s(z1)), s(s(s(z1)))), s(z0), s(s(s(z1)))) the following chains were created:

The constraints for P_> respective P_bound are constructed from P_≥ where we just replace every occurence of "t ≥ s" in P_≥ by "t > s" respective "t ≥ c". Here c stands for the fresh constant used for P_bound.
Using the following integer polynomial ordering the resulting constraints can be solved
Polynomial interpretation [18]:

POL(0) = 0
POL(IF1(x₁, x₂, x₃)) = -1 - x₁ + x₂ - x₃
POL(IF2(x₁, x₂, x₃)) = -1 - x₁ + x₂ - x₃
POL(TEST(x₁, x₂)) = -1 + x₁ - x₂
POL(c) = -5
POL(div(x₁, x₂, x₃)) = 0
POL(false) = 0
POL(gt(x₁, x₂)) = 0
POL(s(x₁)) = 2 + x₁
POL(true) = 0

The following pairs are in P_>:

IF2(false, s(z0), s(s(z1))) → TEST(s(z0), s(s(s(z1))))

The following pairs are in P_bound:

TEST(s(z0), s(s(s(z1)))) → IF1(gt(z0, s(s(z1))), s(z0), s(s(s(z1))))

The following rules are usable:

gt(x, y) → gt(s(x), s(y))
false → gt(0, y)
true → gt(s(x), 0)
div(s(x), s(z), s(z)) → div(s(x), 0, s(z))
div(x, y, z) → div(s(x), s(y), z)
false → div(0, s(x), z)
true → div(0, 0, z)

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

IF1(true, s(z0), s(s(s(z1)))) → IF2(div(z0, s(s(z1)), s(s(s(z1)))), s(z0), s(s(s(z1))))
TEST(s(z0), s(s(s(z1)))) → IF1(gt(z0, s(s(z1))), s(z0), s(s(s(z1))))

The TRS R consists of the following rules:

gt(s(x), 0) → true
gt(0, y) → false
gt(s(x), s(y)) → gt(x, y)
div(0, 0, z) → true
div(0, s(x), z) → false
div(s(x), 0, s(z)) → div(s(x), s(z), s(z))
div(s(x), s(y), z) → div(x, y, z)

The set Q consists of the following terms:

gt(s(x0), 0)
gt(0, x0)
gt(s(x0), s(x1))
div(0, 0, x0)
div(0, s(x0), x1)
div(s(x0), 0, s(x1))
div(s(x0), s(x1), x2)

We have to consider all minimal (P,Q,R)-chains.
The approximation of the Dependency Graph [15,17,22] contains 0 SCCs with 2 less nodes.
