YES(?,ELEMENTARY)
We consider the following Problem:
Strict Trs:
{ f(0()) -> 1()
, f(s(x)) -> g(f(x))
, g(x) -> +(x, s(x))
, f(s(x)) -> +(f(x), s(f(x)))}
StartTerms: basic terms
Strategy: innermost
Certificate: YES(?,ELEMENTARY)
Proof:
The input was oriented with the instance of
Lightweight Multiset Path Order () as induced by the safe mapping
safe(f) = {}, safe(0) = {}, safe(1) = {}, safe(s) = {1},
safe(g) = {1}, safe(+) = {1, 2}
and precedence
f > g .
Following symbols are considered recursive:
{f, g}
The recursion depth is 2 .
For your convenience, here are the oriented rules in predicative
notation (possibly applying argument filtering):
Strict DPs: {}
Weak DPs : {}
Strict Trs:
{ f(0();) -> 1()
, f(s(; x);) -> g(; f(x;))
, g(; x) -> +(; x, s(; x))
, f(s(; x);) -> +(; f(x;), s(; f(x;)))}
Weak Trs : {}
Hurray, we answered YES(?,ELEMENTARY)

YES(?,PRIMREC)
We consider the following Problem:
Strict Trs:
{ f(0()) -> 1()
, f(s(x)) -> g(f(x))
, g(x) -> +(x, s(x))
, f(s(x)) -> +(f(x), s(f(x)))}
StartTerms: basic terms
Strategy: innermost
Certificate: YES(?,PRIMREC)
Proof:
The input was oriented with the instance of
'multiset path orders' as induced by the precedence
f > s, f > g, f > +, 0 > 1, g > s, g > + .
Hurray, we answered YES(?,PRIMREC)
