YES(?,O(n^1))
We are left with following problem, upon which TcT provides the
certificate YES(?,O(n^1)).
Strict Trs:
{ sum(0()) -> 0()
, sum(s(x)) -> +(sqr(s(x)), sum(x))
, sum(s(x)) -> +(*(s(x), s(x)), sum(x))
, sqr(x) -> *(x, x) }
Obligation:
innermost runtime complexity
Answer:
YES(?,O(n^1))
The following argument positions are usable:
Uargs(sum) = {}, Uargs(s) = {}, Uargs(+) = {1, 2}, Uargs(sqr) = {},
Uargs(*) = {}
TcT has computed following constructor-based matrix interpretation
satisfying not(EDA).
[sum](x1) = [2] x1 + [1]
[0] = [0]
[s](x1) = [1] x1 + [2]
[+](x1, x2) = [1] x1 + [1] x2 + [1]
[sqr](x1) = [1]
[*](x1, x2) = [0]
This order satisfies following ordering constraints
[sum(0())] = [1]
> [0]
= [0()]
[sum(s(x))] = [2] x + [5]
> [2] x + [3]
= [+(sqr(s(x)), sum(x))]
[sum(s(x))] = [2] x + [5]
> [2] x + [2]
= [+(*(s(x), s(x)), sum(x))]
[sqr(x)] = [1]
> [0]
= [*(x, x)]
Hurray, we answered YES(?,O(n^1))

YES(?,ELEMENTARY)
We are left with following problem, upon which TcT provides the
certificate YES(?,ELEMENTARY).
Strict Trs:
{ sum(0()) -> 0()
, sum(s(x)) -> +(sqr(s(x)), sum(x))
, sqr(x) -> *(x, x)
, sum(s(x)) -> +(*(s(x), s(x)), sum(x)) }

Answer:
YES(?,ELEMENTARY)
The input was oriented with the instance of 'Lightweight Multiset
Path Order' as induced by the safe mapping
safe(sum) = {}, safe(0) = {}, safe(s) = {1}, safe(+) = {1, 2},
safe(sqr) = {1}, safe(*) = {1, 2}
and precedence
sum > sqr .
Following symbols are considered recursive:
{sum}
The recursion depth is 1.
For your convenience, here are the oriented rules in predicative
notation, possibly applying argument filtering:
