(5) QDPOrderProof (EQUIVALENT transformation)

We use the reduction pair processor [LPAR04].

The following pairs can be oriented strictly and are deleted.

ADX(cons(X, L)) → ACTIVATE(L)
ACTIVATE(n__adx(X)) → ACTIVATE(X)

The remaining pairs can at least be oriented weakly.
Used ordering: Combined order from the following AFS and order.
ACTIVATE(x1)  =  x1
n__incr(x1)  =  x1
INCR(x1)  =  x1
activate(x1)  =  x1
cons(x1, x2)  =  x2
n__adx(x1)  =  n__adx(x1)
ADX(x1)  =  ADX(x1)
incr(x1)  =  x1
adx(x1)  =  adx(x1)
n__zeros  =  n__zeros
zeros  =  zeros
nil  =  nil
s(x1)  =  s(x1)
0  =  0

Lexicographic Path Order [LPO].
Precedence:

[n_adx1, ADX₁, adx₁] > nil
[n_zeros, zeros] > 0

The following usable rules [FROCOS05] were oriented:

activate(n__incr(X)) → incr(activate(X))
activate(n__adx(X)) → adx(activate(X))
activate(n__zeros) → zeros
activate(X) → X
adx(nil) → nil
adx(X) → n__adx(X)
incr(nil) → nil
incr(X) → n__incr(X)
incr(cons(X, L)) → cons(s(X), n__incr(activate(L)))
adx(cons(X, L)) → incr(cons(X, n__adx(activate(L))))
zeros → cons(0, n__zeros)
zeros → n__zeros
