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

(0) Obligation:

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

f(g(x), h(x), y, x) → f(y, y, y, x)
f(x, y, z, 0) → 2
g(0) → 2
h(0) → 2

Rewrite Strategy: INNERMOST

(1) CpxTrsToCdtProof (BOTH BOUNDS(ID, ID) transformation)

Converted CpxTRS to CDT

(2) Obligation:

Complexity Dependency Tuples Problem
Rules:

f(g(z0), h(z0), z1, z0) → f(z1, z1, z1, z0)
f(z0, z1, z2, 0) → 2
g(0) → 2
h(0) → 2

Tuples:

F(g(z0), h(z0), z1, z0) → c(F(z1, z1, z1, z0))

f(z0, z1, z2, 0) → 2
g(0) → 2
h(0) → 2

Tuples:none
S tuples:none
