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

(0) Obligation:

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

quot(0, s(y), s(z)) → 0
quot(s(x), s(y), z) → quot(x, y, z)
quot(x, 0, s(z)) → s(quot(x, s(z), s(z)))

Rewrite Strategy: INNERMOST

(7) CdtRuleRemovalProof (UPPER BOUND(ADD(n^1)) transformation)

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

QUOT(s(z0), s(z1), z2) → c1(QUOT(z0, z1, z2))

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

QUOT(s(z0), s(z1), z2) → c1(QUOT(z0, z1, z2))
QUOT(z0, 0, s(z1)) → c2(QUOT(z0, s(z1), s(z1)))

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

POL(0) = 0   
POL(QUOT(x₁, x₂, x₃)) = [5]x₁   
POL(c1(x₁)) = x₁   
POL(c2(x₁)) = x₁   
POL(s(x₁)) = [1] + x₁

QUOT(z0, 0, s(z1)) → c2(QUOT(z0, s(z1), s(z1)))

S tuples:

QUOT(z0, 0, s(z1)) → c2(QUOT(z0, s(z1), s(z1)))

QUOT(s(z0), s(z1), z2) → c1(QUOT(z0, z1, z2))

(9) CdtKnowledgeProof (EQUIVALENT transformation)

The following tuples could be moved from S to K by knowledge propagation:

QUOT(z0, 0, s(z1)) → c2(QUOT(z0, s(z1), s(z1)))
QUOT(s(z0), s(z1), z2) → c1(QUOT(z0, z1, z2))

Now S is empty
