Termination w.r.t. Q of the following Term Rewriting System could be proven:
Q restricted rewrite system:
The TRS R consists of the following rules:
average(s(x), y) → average(x, s(y))
average(x, s(s(s(y)))) → s(average(s(x), y))
average(0, 0) → 0
average(0, s(0)) → 0
average(0, s(s(0))) → s(0)
Q is empty.

The following Q TRS is given: Q restricted rewrite system:
The TRS R consists of the following rules:
average(s(x), y) → average(x, s(y))
average(x, s(s(s(y)))) → s(average(s(x), y))
average(0, 0) → 0
average(0, s(0)) → 0
average(0, s(s(0))) → s(0)
Q is empty.
The following rules can be removed by the rule removal processor [15] because they are oriented strictly by a polynomial ordering:
average(0, 0) → 0
average(0, s(0)) → 0
average(0, s(s(0))) → s(0)
Used ordering:
Polynomial interpretation [25]:
POL(0) = 0
POL(average(x1, x2)) = 1 + 2·x1 + 2·x2
POL(s(x1)) = x1
