We are left with following problem, upon which TcT provides the
certificate YES(O(1),O(n^1)).
Strict Trs:
{ g(f(x), y) -> f(h(x, y))
, h(x, y) -> g(x, f(y)) }
Obligation:
runtime complexity
Answer:
YES(O(1),O(n^1))
The input is overlay and right-linear. Switching to innermost
rewriting.
We are left with following problem, upon which TcT provides the
certificate YES(O(1),O(n^1)).
Strict Trs:
{ g(f(x), y) -> f(h(x, y))
, h(x, y) -> g(x, f(y)) }

innermost runtime complexity
Answer:
YES(O(1),O(n^1))
We use the processor 'matrix interpretation of dimension 1' to
orient following rules strictly.
Trs:
{ g(f(x), y) -> f(h(x, y))
, h(x, y) -> g(x, f(y)) }
The induced complexity on above rules (modulo remaining rules) is
YES(?,O(n^1)) . These rules are moved into the corresponding weak
component(s).
Sub-proof:
----------
The following argument positions are usable:
Uargs(f) = {1}
TcT has computed the following constructor-based matrix
interpretation satisfying not(EDA).
[g](x1, x2) = [2] x1 + [1]
[f](x1) = [1] x1 + [4]
[h](x1, x2) = [2] x1 + [4]
The order satisfies the following ordering constraints:
[g(f(x), y)] = [2] x + [9]
> [2] x + [8]
= [f(h(x, y))]
[h(x, y)] = [2] x + [4]
> [2] x + [1]
= [g(x, f(y))]
We return to the main proof.

Weak Trs:

, h(x, y) -> g(x, f(y)) }
Obligation:
innermost runtime complexity
Answer:
YES(O(1),O(1))
Empty rules are trivially bounded
Hurray, we answered YES(O(1),O(n^1))
