* Step 1: WeightGap WORST_CASE(?,O(n^1))
+ Considered Problem:
- Strict TRS:
activate(X) -> X
activate(n__from(X)) -> from(X)
after(0(),XS) -> XS
after(s(N),cons(X,XS)) -> after(N,activate(XS))
from(X) -> cons(X,n__from(s(X)))
from(X) -> n__from(X)
- Signature:
{activate/1,after/2,from/1} / {0/0,cons/2,n__from/1,s/1}
- Obligation:
runtime complexity wrt. defined symbols {activate,after,from} and constructors {0,cons,n__from,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(after) = {2}
Following symbols are considered usable:
all
TcT has computed the following interpretation:
p(0) = [0]
p(activate) = [1] x1 + [0]
p(after) = [1] x2 + [11]
p(cons) = [1] x2 + [0]
p(from) = [1] x1 + [1]
p(n__from) = [1] x1 + [0]
p(s) = [1] x1 + [0]
Following rules are strictly oriented:
after(0(),XS) = [1] XS + [11]
> [1] XS + [0]
= XS
from(X) = [1] X + [1]
> [1] X + [0]
= cons(X,n__from(s(X)))
from(X) = [1] X + [1]
> [1] X + [0]
= n__from(X)
Following rules are (at-least) weakly oriented:
activate(X) = [1] X + [0]
>= [1] X + [0]
= X
activate(n__from(X)) = [1] X + [0]
>= [1] X + [1]
= from(X)
after(s(N),cons(X,XS)) = [1] XS + [11]
>= [1] XS + [11]
= after(N,activate(XS))
Further, it can be verified that all rules not oriented are covered by the weightgap condition.

p(cons) = [1] x_2 + [0]
p(from) = [0]

p(s) = [1] x_1 + [1]
Following rules are strictly oriented:

= from(X)
after(s(N),cons(X,XS)) = [7] N + [1] XS + [19]

= XS
from(X) = [0]
>= [0]
= cons(X,n__from(s(X)))
