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