Runtime Complexity TRS:
The TRS R consists of the following rules:

h(z, e(x)) → h(c(z), d(z, x))
d(z, g(0, 0)) → e(0)
d(z, g(x, y)) → g(e(x), d(z, y))
d(c(z), g(g(x, y), 0)) → g(d(c(z), g(x, y)), d(z, g(x, y)))
g(e(x), e(y)) → e(g(x, y))

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

We considered the (Usable) Rules:none
And the Tuples:

G(e(z0), e(z1)) → c5(G(z0, z1))
The order we found is given by the following interpretation:

POL(G(x1, x2)) = [2]x1
POL(c5(x1)) = x1
POL(e(x1)) = [1] + x1
