YES

We show the termination of the TRS R:

  g(|0|()) -> |0|()
  g(s(x)) -> f(g(x))
  f(|0|()) -> |0|()

-- SCC decomposition.

Consider the dependency pair problem (P, R), where P consists of

p1: g#(s(x)) -> f#(g(x))
p2: g#(s(x)) -> g#(x)

and R consists of:

r1: g(|0|()) -> |0|()
r2: g(s(x)) -> f(g(x))
r3: f(|0|()) -> |0|()

The estimated dependency graph contains the following SCCs:

  {p2}


-- Reduction pair.

Consider the dependency pair problem (P, R), where P consists of

p1: g#(s(x)) -> g#(x)

and R consists of:

r1: g(|0|()) -> |0|()
r2: g(s(x)) -> f(g(x))
r3: f(|0|()) -> |0|()

The set of usable rules consists of

  (no rules)

Take the monotone reduction pair:

  matrix interpretations:
  
    carrier: N^2
    order: standard order
    interpretations:
      g#_A(x1) = ((1,0),(1,0)) x1
      s_A(x1) = ((1,1),(1,1)) x1 + (1,0)

The next rules are strictly ordered:

  p1
  r1, r2, r3

We remove them from the problem.  Then no dependency pair remains.
