The Runtime Complexity (innermost) of the given
CpxTRS could be proven to be
BOUNDS(1, n^1).
The TRS R consists of the following rules:
f(x, y) → g(x, y)
g(h(x), y) → h(f(x, y))
g(h(x), y) → h(g(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:
h0(0) → 0
f0(0, 0) → 1
g0(0, 0) → 2
g1(0, 0) → 1
f1(0, 0) → 3
h1(3) → 2
g1(0, 0) → 4
h1(4) → 2
g2(0, 0) → 3
h1(3) → 1
h1(3) → 4
h1(4) → 1
h1(4) → 4
h1(3) → 3
h1(4) → 3
