Q is empty.
The following rules can be removed by the rule removal processor [15] because they are oriented strictly by a polynomial ordering:
+(x, 0) → x
+(0, y) → y
f(g(h(x, y))) → f(h(s(x), y))
f(h(x, h(y, z))) → f(h(+(x, y), z))
Used ordering:
Polynomial interpretation [25]:
POL(+(x1, x2)) = 1 + x1 + x2
POL(0) = 1
POL(f(x1)) = 1 + x1
POL(g(x1)) = 2 + 2·x1
POL(h(x1, x2)) = 1 + x1 + 2·x2
POL(s(x1)) = 2 + x1
