The Runtime Complexity (innermost) of the given CpxTRS could be proven to be BOUNDS(O(1), O(n^2)).

(0) Obligation:

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

norm(nil) → 0
norm(g(x, y)) → s(norm(x))
f(x, nil) → g(nil, x)
f(x, g(y, z)) → g(f(x, y), z)
rem(nil, y) → nil
rem(g(x, y), 0) → g(x, y)
rem(g(x, y), s(z)) → rem(x, z)

Rewrite Strategy: INNERMOST

(3) 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.

NORM(g(z0, z1)) → c1(NORM(z0))
F(z0, g(z1, z2)) → c3(F(z0, z1))

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

NORM(g(z0, z1)) → c1(NORM(z0))
F(z0, g(z1, z2)) → c3(F(z0, z1))
REM(g(z0, z1), s(z2)) → c6(REM(z0, z2))

The order we found is given by the following interpretation:
Polynomial interpretation :

POL(F(x₁, x₂)) = x₂   
POL(NORM(x₁)) = [2]x₁   
POL(REM(x₁, x₂)) = [3]x₂
