(8) QDPOrderProof (EQUIVALENT transformation)

We use the reduction pair processor [LPAR04]. Here, we combined the reduction pair processor with the A-transformation [FROCOS05] which results in the following intermediate Q-DP Problem.
The a-transformed P is

app1(add(n, x), y) → app1(x, y)

The a-transformed usable rules are
none

The following pairs can be oriented strictly and are deleted.

APP'(app'(app, app'(app'(add, n), x)), y) → APP'(app'(app, x), y)

The remaining pairs can at least be oriented weakly.
Used ordering: Combined order from the following AFS and order.
app1(x1, x2) = app1(x1)
add(x1, x2) = add(x2)

Lexicographic path order with status [LPO].
Precedence:

(34) QDPOrderProof (EQUIVALENT transformation)

We use the reduction pair processor [LPAR04].

The following pairs can be oriented strictly and are deleted.

APP'(app'(map, f), app'(app'(add, x), xs)) → APP'(app'(map, f), xs)
APP'(app'(map, f), app'(app'(add, x), xs)) → APP'(f, x)
APP'(app'(filter, f), app'(app'(add, x), xs)) → APP'(app'(app'(app'(filter2, app'(f, x)), f), x), xs)
APP'(app'(filter, f), app'(app'(add, x), xs)) → APP'(f, x)

The remaining pairs can at least be oriented weakly.
Used ordering: Combined order from the following AFS and order.
APP'(x1, x2) = APP'(x2)
app'(x1, x2) = app'(x1, x2)
map = map
add = add
filter = filter
filter2 = filter2
true = true
false = false
eq = eq
0 = 0
s = s
le = le
app = app
nil = nil
min = min
if_min = if_min
rm = rm
if_rm = if_rm
minsort = minsort
if_minsort = if_minsort

Lexicographic path order with status [LPO].
Precedence:

APP'₁ > app'₂
APP'₁ > map
APP'₁ > filter
APP'₁ > filter2

Status:

APP'₁: [1]
app'₂: [1,2]
