```* Step 1: WeightGap WORST_CASE(?,O(n^2))
+ Considered Problem:
- Strict TRS:
f(x,c(y)) -> f(x,s(f(y,y)))
f(s(x),s(y)) -> f(x,s(c(s(y))))
- Signature:
{f/2} / {c/1,s/1}
- Obligation:
innermost runtime complexity wrt. defined symbols {f} and constructors {c,s}
+ Applied Processor:
WeightGap {wgDimension = 1, wgDegree = 1, wgKind = Algebraic, wgUArgs = UArgs, wgOn = WgOnAny}
+ Details:
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) = {2},
uargs(s) = {1}

Following symbols are considered usable:
all
TcT has computed the following interpretation:
p(c) =  x1 + 
p(f) =  x2 + 
p(s) =  x1 + 

Following rules are strictly oriented:
f(x,c(y)) =  y + 
>  y + 
= f(x,s(f(y,y)))

Following rules are (at-least) weakly oriented:
f(s(x),s(y)) =   y + 
>=  y + 
=  f(x,s(c(s(y))))

Further, it can be verified that all rules not oriented are covered by the weightgap condition.
