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


The TRS R consists of the following rules:

   f(a, empty) -> g(a, empty)
   f(a, cons(x, k)) -> f(cons(x, a), k)
   g(empty, d) -> d
   g(cons(x, k), d) -> g(k, cons(x, d))

S is empty.
Rewrite Strategy: PARALLEL_INNERMOST

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


The TRS R consists of the following rules:

   f(a, empty) -> g(a, empty)
   f(a, cons(x, k)) -> f(cons(x, a), k)
   g(empty, d) -> d
   g(cons(x, k), d) -> g(k, cons(x, d))

S is empty.

(3) CpxTrsMatchBoundsTAProof (FINISHED)
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: 
empty0() -> 0
cons0(0, 0) -> 0
f0(0, 0) -> 1
g0(0, 0) -> 2
empty1() -> 3
g1(0, 3) -> 1
cons1(0, 0) -> 4
f1(4, 0) -> 1
cons1(0, 0) -> 5
g1(0, 5) -> 2
g1(4, 3) -> 1
cons1(0, 4) -> 4
cons1(0, 3) -> 5
g1(0, 5) -> 1
cons1(0, 5) -> 5
cons2(0, 3) -> 6
g2(0, 6) -> 1
g2(4, 6) -> 1
cons1(0, 6) -> 5
cons2(0, 6) -> 6
0 -> 2
3 -> 1
5 -> 2
5 -> 1
6 -> 1
