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

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

h(f(x), y) → f(g(x, y))
g(x, y) → h(x, y)

Rewrite Strategy: INNERMOST

(1) CpxTrsMatchBoundsTAProof (EQUIVALENT transformation)

A linear upper bound on the runtime complexity of the TRS R could be shown with a Match-Bound[TAB_LEFTLINEAR,TAB_NONLEFTLINEAR] (for contructor-based start-terms) of 2.

The compatible tree automaton used to show the Match-Boundedness (for constructor-based start-terms) is represented by:
final states : [1, 2]
transitions:
f0(0) → 0
h0(0, 0) → 1
g0(0, 0) → 2
g1(0, 0) → 3
f1(3) → 1
h1(0, 0) → 2
f1(3) → 2
h2(0, 0) → 3
f1(3) → 3
