The Runtime Complexity (innermost) of the given CpxTRS could be proven to be BOUNDS(n^2, INF).


The TRS R consists of the following rules:

   max(nil) -> 0
   max(cons(x, nil)) -> x
   max(cons(x, cons(y, xs))) -> if1(ge(x, y), x, y, xs)
   if1(true, x, y, xs) -> max(cons(x, xs))
   if1(false, x, y, xs) -> max(cons(y, xs))
   del(x, nil) -> nil
   del(x, cons(y, xs)) -> if2(eq(x, y), x, y, xs)
   if2(true, x, y, xs) -> xs
   if2(false, x, y, xs) -> cons(y, del(x, xs))
   eq(0, 0) -> true
   eq(0, s(y)) -> false
   eq(s(x), 0) -> false
   eq(s(x), s(y)) -> eq(x, y)
   sort(nil) -> nil
   sort(cons(x, xs)) -> cons(max(cons(x, xs)), sort(h(del(max(cons(x, xs)), cons(x, xs)))))
   ge(0, 0) -> true
   ge(s(x), 0) -> true
   ge(0, s(x)) -> false
   ge(s(x), s(y)) -> ge(x, y)
   h(nil) -> nil
   h(cons(x, xs)) -> cons(x, h(xs))
