Obligation:
Context-sensitive rewrite system:
The TRS R consists of the following rules:

   nats -> adx(zeros)
   zeros -> cons(0, zeros)
   incr(cons(X, Y)) -> cons(s(X), incr(Y))
   adx(cons(X, Y)) -> incr(cons(X, adx(Y)))
   hd(cons(X, Y)) -> X
   tl(cons(X, Y)) -> Y

The replacement map contains the following entries:

nats: empty set
adx: {1}
zeros: empty set
cons: empty set
0: empty set
incr: {1}
s: empty set
hd: {1}

Used ordering:
Polynomial interpretation [POLO]:

   POL(0) = 0
   POL(adx(x_1)) = x_1
   POL(cons(x_1, x_2)) = x_1 + x_2
   POL(hd(x_1)) = 2*x_1
