Term Rewriting System R:
[l, x, k, a, b, c]
f(empty, l) -> l
f(cons(x, k), l) -> g(k, l, cons(x, k))
g(a, b, c) -> f(a, cons(b, c))
Innermost Termination of R to be shown.
R
↳Dependency Pair Analysis
R contains the following Dependency Pairs:
F(cons(x, k), l) -> G(k, l, cons(x, k))
G(a, b, c) -> F(a, cons(b, c))
Furthermore, R contains one SCC.

↳Argument Filtering and Ordering
Dependency Pairs:
G(a, b, c) -> F(a, cons(b, c))
F(cons(x, k), l) -> G(k, l, cons(x, k))
Rules:
f(empty, l) -> l
f(cons(x, k), l) -> g(k, l, cons(x, k))
g(a, b, c) -> f(a, cons(b, c))
Strategy:
innermost
The following dependency pair can be strictly oriented:
F(cons(x, k), l) -> G(k, l, cons(x, k))
There are no usable rules for innermost w.r.t. to the AFS that need to be oriented.
Used ordering: Homeomorphic Embedding Order with EMB
resulting in one new DP problem.
Used Argument Filtering System: G(x1, x2, x3) -> x1
F(x1, x2) -> x1
cons(x1, x2) -> cons(x1, x2)

↳Dependency Graph
Dependency Pair:
G(a, b, c) -> F(a, cons(b, c))
Rules:
f(empty, l) -> l
f(cons(x, k), l) -> g(k, l, cons(x, k))
g(a, b, c) -> f(a, cons(b, c))
Strategy:
innermost
Using the Dependency Graph resulted in no new DP problems.
