YES(?,POLY)

We are left with following problem, upon which TcT provides the
certificate YES(?,POLY).

Strict Trs: { f(g(x), y, y) -> g(f(x, x, y)) }
Obligation:
  innermost runtime complexity
Answer:
  YES(?,POLY)

The input was oriented with the instance of 'Polynomial Path Order'
as induced by the safe mapping

 safe(f) = {3}, safe(g) = {1}

and precedence

 empty .

Following symbols are considered recursive:

 {f}

The recursion depth is 1.

For your convenience, here are the satisfied ordering constraints:

  f(g(; x),  y; y) > g(; f(x,  x; y))
                                     

Hurray, we answered YES(?,POLY)
