Term Rewriting System R:
[X, Y]
from(X) -> cons(X, from(s(X)))
length(nil) -> 0
length(cons(X, Y)) -> s(length1(Y))
length1(X) -> length(X)

Innermost Termination of R to be shown.

Dependency Pair Analysis



R contains the following Dependency Pairs:

FROM(X) -> FROM(s(X))
LENGTH(cons(X, Y)) -> LENGTH1(Y)
LENGTH1(X) -> LENGTH(X)

Furthermore, R contains two SCCs.
