Matrix type:
We used a basic matrix type which is not further parametrizeable.
As matrix orders are CE-compatible, we used usable rules w.r.t. argument filtering in the order.
The following usable rules [17] were oriented:

new_primMinusNatS0(Zero, Zero) → Zero
new_primMinusNatS0(Succ(vuz1180), Succ(vuz1190)) → new_primMinusNatS0(vuz1180, vuz1190)

Matrix type:
We used a basic matrix type which is not further parametrizeable.
As matrix orders are CE-compatible, we used usable rules w.r.t. argument filtering in the order.
The following usable rules [17] were oriented:
new_primMinusNatS0(Succ(vuz1180), Zero) → Succ(vuz1180)
new_primMinusNatS0(Zero, Zero) → Zero
new_primMinusNatS0(Succ(vuz1180), Succ(vuz1190)) → new_primMinusNatS0(vuz1180, vuz1190)
new_primMinusNatS0(Zero, Succ(vuz1190)) → Zero

The constraints for P> respective Pbound 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 Pbound.
Using the following integer polynomial ordering the resulting constraints can be solved
Polynomial interpretation [18]:
POL(Succ(x1)) = 1 + x1
POL(Zero) = 0
POL(c) = -1
POL(new_gcd0Gcd'1(x1, x2, x3)) = -1 - x1 + x2 + x3
POL(new_gcd0Gcd'10(x1, x2, x3, x4)) = -1 + x1 - x3 + x4
POL(new_gcd0Gcd'12(x1, x2)) = -1 + x1
POL(new_gcd0Gcd'13(x1, x2)) = -1 + x2
The following pairs are in P>:
new_gcd0Gcd'1(Succ(Succ(x0)), Succ(x1), Succ(Succ(x0))) → new_gcd0Gcd'10(x0, Succ(x1), x0, x1)
The following pairs are in Pbound:
