DependencyPairs {dpKind_ = DT}
Proof:
We add the following weak dependency pairs:
Strict DPs
f#(0(),y) -> c_1()
f#(s(x),y) -> c_2(f#(f(x,y),y))
Weak DPs
and mark the set of starting terms.

Proof:
We estimate the number of application of

Here rules are labelled as follows:

WeightGap {wgDimension = 1, wgDegree = 0, wgKind = Algebraic, wgUArgs = UArgs, wgOn = WgOnAny}
Proof:
The weightgap principle applies using the following nonconstant growth matrix-interpretation:
We apply a matrix interpretation of kind constructor based matrix interpretation:
The following argument positions are considered usable:
uargs(f) = {1},
uargs(f#) = {1},
uargs(c_2) = {1}
Following symbols are considered usable:

TcT has computed the following interpretation:
p(0) = [0]
p(f) = [1] x1 + [0]
p(s) = [1] x1 + [3]
p(f#) = [1] x1 + [0]
p(c_1) = [0]
p(c_2) = [1] x1 + [0]
Following rules are strictly oriented:
f#(s(x),y) = [1] x + [3]
> [1] x + [0]
= c_2(f#(f(x,y),y))
f(s(x),y) = [1] x + [3]
> [1] x + [0]
= f(f(x,y),y)
Following rules are (at-least) weakly oriented:
f#(0(),y) = [0]
>= [0]
= c_1()
f(0(),y) = [0]
>= [0]
= 0()
Further, it can be verified that all rules not oriented are covered by the weightgap condition.
