By using the subterm criterion [20] together with the size-change analysis [32] we have proven that there are no infinite chains for this DP problem.

From the DPs we obtained the following set of size-change graphs:

APP(app(forsome, p), app(app(cons, x), xs)) → APP(p, x)
The graph contains the following edges 1 > 1, 2 > 2
APP(app(forsome, p), app(app(cons, x), xs)) → APP(app(forsome, p), xs)
The graph contains the following edges 1 >= 1, 2 > 2
APP(app(forall, p), app(app(cons, x), xs)) → APP(p, x)
The graph contains the following edges 1 > 1, 2 > 2
APP(app(forall, p), app(app(cons, x), xs)) → APP(app(forall, p), xs)
The graph contains the following edges 1 >= 1, 2 > 2
