We are left with following problem, upon which TcT provides the
certificate YES(O(1),O(1)).
Strict Trs:
{ g(x, y) -> x
, g(x, y) -> y
, f(s(x), y, y) -> f(y, x, s(x)) }
Obligation:
innermost runtime complexity
Answer:
YES(O(1),O(1))
We add the following weak dependency pairs:
Strict DPs:
{ g^#(x, y) -> c_1()
, g^#(x, y) -> c_2()
, f^#(s(x), y, y) -> c_3(f^#(y, x, s(x))) }
and mark the set of starting terms.

No rule is usable, rules are removed from the input problem.

Answer:
YES(O(1),O(1))
The weightgap principle applies (using the following constant
growth matrix-interpretation)
The following argument positions are usable:
none
TcT has computed the following constructor-restricted matrix
interpretation.
[s](x1) = [0]
[0]
[g^#](x1, x2) = [2]
[0]
[c_1] = [0]
[0]
[c_2] = [0]
[0]
[f^#](x1, x2, x3) = [0]
[0]
[c_3](x1) = [0]
[0]
The order satisfies the following ordering constraints:
[g^#(x, y)] = [2]
[0]
> [0]
[0]
= [c_1()]
[g^#(x, y)] = [2]
[0]
> [0]
[0]
= [c_2()]
[f^#(s(x), y, y)] = [0]
[0]
>= [0]
[0]
= [c_3(f^#(y, x, s(x)))]
Further, it can be verified that all rules not oriented are covered by the weightgap condition.

Answer:
YES(O(1),O(1))
We estimate the number of application of {1} by applications of
Pre({1}) = {}. Here rules are labeled as follows:
DPs:
{ 1: f^#(s(x), y, y) -> c_3(f^#(y, x, s(x)))
, 2: g^#(x, y) -> c_1()
, 3: g^#(x, y) -> c_2() }
We are left with following problem, upon which TcT provides the
certificate YES(O(1),O(1)).
Weak DPs:
{ g^#(x, y) -> c_1()
, g^#(x, y) -> c_2()
, f^#(s(x), y, y) -> c_3(f^#(y, x, s(x))) }
Obligation:

Answer:
YES(O(1),O(1))
The following weak DPs constitute a sub-graph of the DG that is
closed under successors. The DPs are removed.
{ g^#(x, y) -> c_1()
, g^#(x, y) -> c_2()
, f^#(s(x), y, y) -> c_3(f^#(y, x, s(x))) }

Rules: Empty
Obligation:

Answer:
YES(O(1),O(1))
Empty rules are trivially bounded
Hurray, we answered YES(O(1),O(1))
