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:

filter₃(cons₁(X), 0, M) -> cons₁(0)
filter₃(cons₁(X), s₁(N), M) -> cons₁(X)
sieve₁(cons₁(0)) -> cons₁(0)
sieve₁(cons₁(s₁(N))) -> cons₁(s₁(N))
nats₁(N) -> cons₁(N)
zprimes -> sieve₁(nats₁(s₁(s₁(0))))

Q is empty.

Q restricted rewrite system:
The TRS R consists of the following rules:

filter₃(cons₁(X), 0, M) -> cons₁(0)
filter₃(cons₁(X), s₁(N), M) -> cons₁(X)
sieve₁(cons₁(0)) -> cons₁(0)
sieve₁(cons₁(s₁(N))) -> cons₁(s₁(N))

Q is empty.

The TRS is non-overlapping. Hence, we can switch to innermost.

Using Dependency Pairs [1,13] we result in the following initial DP problem:
