(11) CdtPolyRedPairProof (UPPER BOUND (ADD(O(n^1))) transformation)

Found a reduction pair which oriented the following tuples strictly. Hence they can be removed from S.

COND(true, s(z0), x1) → c(COND(gr(s(z0), x1), z0, x1), GR(s(z0), x1))
We considered the (Usable) Rules:

p(s(z0)) → z0
gr(0, z0) → false
gr(s(z0), 0) → true
gr(s(z0), s(z1)) → gr(z0, z1)
And the Tuples:

GR(s(z0), s(z1)) → c3(GR(z0, z1))
COND(true, s(z0), x1) → c(COND(gr(s(z0), x1), z0, x1), GR(s(z0), x1))
COND(true, s(z0), s(z1)) → c(COND(gr(z0, z1), p(s(z0)), s(z1)), GR(s(z0), s(z1)))
COND(true, 0, x1) → c(COND(gr(0, x1), 0, x1))
COND(true, s(z0), 0) → c(COND(true, p(s(z0)), 0))
The order we found is given by the following interpretation:
Polynomial interpretation :

POL(0) = 0   
POL(COND(x1, x2, x3)) = x2   
POL(GR(x1, x2)) = 0   
POL(c(x1)) = x1   
POL(c(x1, x2)) = x1 + x2   
POL(c3(x1)) = x1   
POL(false) = [2]   
POL(gr(x1, x2)) = [5] + [2]x2   
POL(p(x1)) = x1   
POL(s(x1)) = [1] + x1

gr(s(z0), s(z1)) → gr(z0, z1)
And the Tuples:

COND(true, s(z0), s(z1)) → c(COND(gr(z0, z1), z0, s(z1)), GR(s(z0), s(z1)))
COND(true, s(z0), 0) → c(COND(true, z0, 0))
GR(s(s(y0)), s(s(y1))) → c3(GR(s(y0), s(y1)))
COND(true, s(s(z0)), s(s(z1))) → c(COND(gr(z0, z1), s(z0), s(s(z1))), GR(s(s(z0)), s(s(z1))))
COND(true, s(s(z0)), s(0)) → c(COND(true, s(z0), s(0)))
The order we found is given by the following interpretation:
Polynomial interpretation :

POL(0) = [5]   
POL(COND(x1, x2, x3)) = x2   
POL(GR(x1, x2)) = 0   
POL(c(x1)) = x1   
POL(c(x1, x2)) = x1 + x2   
POL(c3(x1)) = x1   
POL(false) = [3]   
POL(gr(x1, x2)) = [4] + [4]x1 + [5]x2   
POL(s(x1)) = [1] + x1   
POL(true) = [4]
