Answer:
  YES(O(1),O(n^1))

The weightgap principle applies (using the following nonconstant
growth matrix-interpretation)

The following argument positions are usable:
  Uargs(__) = {2}, Uargs(and) = {1, 2}, Uargs(activate) = {1},
  Uargs(isList) = {1}, Uargs(isNeList) = {1}, Uargs(n____) = {2},
  Uargs(n__isList) = {1}, Uargs(isQid) = {1},
  Uargs(n__isNeList) = {1}, Uargs(isNePal) = {1},
  Uargs(n__isPal) = {1}, Uargs(isPal) = {1}

TcT has computed the following matrix interpretation satisfying
not(EDA) and not(IDA(1)).

Answer:
  YES(O(1),O(n^1))

The weightgap principle applies (using the following nonconstant
growth matrix-interpretation)

The following argument positions are usable:
  Uargs(__) = {2}, Uargs(and) = {1, 2}, Uargs(activate) = {1},
  Uargs(isList) = {1}, Uargs(isNeList) = {1}, Uargs(n____) = {2},
  Uargs(n__isList) = {1}, Uargs(isQid) = {1},
  Uargs(n__isNeList) = {1}, Uargs(isNePal) = {1},
  Uargs(n__isPal) = {1}, Uargs(isPal) = {1}

Further, it can be verified that all rules not oriented are covered by the weightgap condition.

We are left with following problem, upon which TcT provides the
certificate YES(O(1),O(n^1)).

Answer:
  YES(O(1),O(n^1))

The weightgap principle applies (using the following nonconstant
growth matrix-interpretation)

The following argument positions are usable:
  Uargs(__) = {2}, Uargs(and) = {1, 2}, Uargs(activate) = {1},
  Uargs(isList) = {1}, Uargs(isNeList) = {1}, Uargs(n____) = {2},
  Uargs(n__isList) = {1}, Uargs(isQid) = {1},
  Uargs(n__isNeList) = {1}, Uargs(isNePal) = {1},
  Uargs(n__isPal) = {1}, Uargs(isPal) = {1}

Further, it can be verified that all rules not oriented are covered by the weightgap condition.

We are left with following problem, upon which TcT provides the
certificate YES(O(1),O(n^1)).

Answer:
  YES(O(1),O(n^1))

The weightgap principle applies (using the following nonconstant
growth matrix-interpretation)

The following argument positions are usable:
  Uargs(__) = {2}, Uargs(and) = {1, 2}, Uargs(activate) = {1},
  Uargs(isList) = {1}, Uargs(isNeList) = {1}, Uargs(n____) = {2},
  Uargs(n__isList) = {1}, Uargs(isQid) = {1},
  Uargs(n__isNeList) = {1}, Uargs(isNePal) = {1},
  Uargs(n__isPal) = {1}, Uargs(isPal) = {1}

Further, it can be verified that all rules not oriented are covered by the weightgap condition.

We are left with following problem, upon which TcT provides the
certificate YES(O(1),O(n^1)).

Strict Trs:
  { __(X1, X2) -> n____(X1, X2)

Obligation:

Answer:
  YES(O(1),O(n^1))

The weightgap principle applies (using the following nonconstant
growth matrix-interpretation)

The following argument positions are usable:
  Uargs(__) = {2}, Uargs(and) = {1, 2}, Uargs(activate) = {1},
  Uargs(isList) = {1}, Uargs(isNeList) = {1}, Uargs(n____) = {2},
  Uargs(n__isList) = {1}, Uargs(isQid) = {1},
  Uargs(n__isNeList) = {1}, Uargs(isNePal) = {1},
  Uargs(n__isPal) = {1}, Uargs(isPal) = {1}

Further, it can be verified that all rules not oriented are covered by the weightgap condition.

We are left with following problem, upon which TcT provides the
certificate YES(O(1),O(n^1)).

Strict Trs:
  { __(X1, X2) -> n____(X1, X2)
  , __(__(X, Y), Z) -> __(X, __(Y, Z))
  , nil() -> n__nil()
  , and(tt(), X) -> activate(X)
  , activate(X) -> X
  , activate(n__isList(X)) -> isList(X)
  , activate(n__isPal(X)) -> isPal(X)
  , activate(n__a()) -> a()
  , activate(n__e()) -> e()
  , activate(n__i()) -> i()
  , activate(n__o()) -> o()
  , activate(n__u()) -> u()
  , isNeList(X) -> n__isNeList(X)

Obligation:
  runtime complexity
Answer:
  YES(O(1),O(n^1))

The weightgap principle applies (using the following nonconstant
growth matrix-interpretation)

The following argument positions are usable:
  Uargs(__) = {2}, Uargs(and) = {1, 2}, Uargs(activate) = {1},
  Uargs(isList) = {1}, Uargs(isNeList) = {1}, Uargs(n____) = {2},
  Uargs(n__isList) = {1}, Uargs(isQid) = {1},
  Uargs(n__isNeList) = {1}, Uargs(isNePal) = {1},
  Uargs(n__isPal) = {1}, Uargs(isPal) = {1}

Further, it can be verified that all rules not oriented are covered by the weightgap condition.

We are left with following problem, upon which TcT provides the
certificate YES(O(1),O(n^1)).

Answer:
  YES(O(1),O(n^1))

The weightgap principle applies (using the following nonconstant
growth matrix-interpretation)

The following argument positions are usable:
  Uargs(__) = {2}, Uargs(and) = {1, 2}, Uargs(activate) = {1},
  Uargs(isList) = {1}, Uargs(isNeList) = {1}, Uargs(n____) = {2},
  Uargs(n__isList) = {1}, Uargs(isQid) = {1},
  Uargs(n__isNeList) = {1}, Uargs(isNePal) = {1},
  Uargs(n__isPal) = {1}, Uargs(isPal) = {1}

The order satisfies the following ordering constraints:

Answer:
  YES(O(1),O(n^1))

The weightgap principle applies (using the following nonconstant
growth matrix-interpretation)

The following argument positions are usable:
  Uargs(__) = {2}, Uargs(and) = {1, 2}, Uargs(activate) = {1},
  Uargs(isList) = {1}, Uargs(isNeList) = {1}, Uargs(n____) = {2},
  Uargs(n__isList) = {1}, Uargs(isQid) = {1},
  Uargs(n__isNeList) = {1}, Uargs(isNePal) = {1},
  Uargs(n__isPal) = {1}, Uargs(isPal) = {1}

The order satisfies the following ordering constraints:

Answer:
  YES(O(1),O(n^1))

The weightgap principle applies (using the following nonconstant
growth matrix-interpretation)

The following argument positions are usable:
  Uargs(__) = {2}, Uargs(and) = {1, 2}, Uargs(activate) = {1},
  Uargs(isList) = {1}, Uargs(isNeList) = {1}, Uargs(n____) = {2},
  Uargs(n__isList) = {1}, Uargs(isQid) = {1},
  Uargs(n__isNeList) = {1}, Uargs(isNePal) = {1},
  Uargs(n__isPal) = {1}, Uargs(isPal) = {1}

Answer:
  YES(O(1),O(n^1))

The weightgap principle applies (using the following nonconstant
growth matrix-interpretation)

The following argument positions are usable:
  Uargs(__) = {2}, Uargs(and) = {1, 2}, Uargs(activate) = {1},
  Uargs(isList) = {1}, Uargs(isNeList) = {1}, Uargs(n____) = {2},
  Uargs(n__isList) = {1}, Uargs(isQid) = {1},
  Uargs(n__isNeList) = {1}, Uargs(isNePal) = {1},
  Uargs(n__isPal) = {1}, Uargs(isPal) = {1}

Answer:
  YES(O(1),O(n^1))

The weightgap principle applies (using the following nonconstant
growth matrix-interpretation)

The following argument positions are usable:
  Uargs(__) = {2}, Uargs(and) = {1, 2}, Uargs(activate) = {1},
  Uargs(isList) = {1}, Uargs(isNeList) = {1}, Uargs(n____) = {2},
  Uargs(n__isList) = {1}, Uargs(isQid) = {1},
  Uargs(n__isNeList) = {1}, Uargs(isNePal) = {1},
  Uargs(n__isPal) = {1}, Uargs(isPal) = {1}

TcT has computed the following matrix interpretation satisfying
not(EDA) and not(IDA(1)).

       [__](x1, x2) = [1] x1 + [1] x2 + [0]
                                           
              [nil] = [0]                  
                                           
      [and](x1, x2) = [1] x1 + [1] x2 + [1]
                                           
               [tt] = [0]

We are left with following problem, upon which TcT provides the
certificate YES(O(1),O(n^1)).

Strict Trs:

  , activate(n__isList(X)) -> isList(X)
  , activate(n__isPal(X)) -> isPal(X)
  , activate(n__a()) -> a()
  , activate(n__e()) -> e()
  , activate(n__i()) -> i()
  , activate(n__o()) -> o()
  , activate(n__u()) -> u()
  , isNeList(X) -> n__isNeList(X) }
Weak Trs:

Answer:
  YES(O(1),O(n^1))

The weightgap principle applies (using the following nonconstant
growth matrix-interpretation)

The following argument positions are usable:
  Uargs(__) = {2}, Uargs(and) = {1, 2}, Uargs(activate) = {1},

The weightgap principle applies (using the following nonconstant
growth matrix-interpretation)

The following argument positions are usable:
  Uargs(__) = {2}, Uargs(and) = {1, 2}, Uargs(activate) = {1},
  Uargs(isList) = {1}, Uargs(isNeList) = {1}, Uargs(n____) = {2},
  Uargs(n__isList) = {1}, Uargs(isQid) = {1},
  Uargs(n__isNeList) = {1}, Uargs(isNePal) = {1},
  Uargs(n__isPal) = {1}, Uargs(isPal) = {1}

The weightgap principle applies (using the following nonconstant
growth matrix-interpretation)

The following argument positions are usable:
  Uargs(__) = {2}, Uargs(and) = {1, 2}, Uargs(activate) = {1},
  Uargs(isList) = {1}, Uargs(isNeList) = {1}, Uargs(n____) = {2},
  Uargs(n__isList) = {1}, Uargs(isQid) = {1},
  Uargs(n__isNeList) = {1}, Uargs(isNePal) = {1},
  Uargs(n__isPal) = {1}, Uargs(isPal) = {1}

Further, it can be verified that all rules not oriented are covered by the weightgap condition.

We are left with following problem, upon which TcT provides the
certificate YES(O(1),O(n^1)).

  , __(nil(), X) -> X
  , nil() -> n__nil()
  , and(tt(), X) -> activate(X)
  , activate(X) -> X
  , activate(n__nil()) -> nil()
  , activate(n____(X1, X2)) -> __(X1, X2)
  , activate(n__isList(X)) -> isList(X)
  , activate(n__isNeList(X)) -> isNeList(X)

Obligation:
  runtime complexity
Answer:
  YES(O(1),O(n^1))

The weightgap principle applies (using the following nonconstant
growth matrix-interpretation)

The following argument positions are usable:
  Uargs(__) = {2}, Uargs(and) = {1, 2}, Uargs(activate) = {1},
  Uargs(isList) = {1}, Uargs(isNeList) = {1}, Uargs(n____) = {2},
  Uargs(n__isList) = {1}, Uargs(isQid) = {1},
  Uargs(n__isNeList) = {1}, Uargs(isNePal) = {1},
  Uargs(n__isPal) = {1}, Uargs(isPal) = {1}

TcT has computed the following matrix interpretation satisfying
not(EDA) and not(IDA(1)).

The order satisfies the following ordering constraints:

Further, it can be verified that all rules not oriented are covered by the weightgap condition.

We are left with following problem, upon which TcT provides the
certificate YES(O(1),O(n^1)).

Strict Trs: { __(__(X, Y), Z) -> __(X, __(Y, Z)) }
Weak Trs:
  { __(X1, X2) -> n____(X1, X2)
  , __(X, nil()) -> X
  , __(nil(), X) -> X
  , nil() -> n__nil()
  , and(tt(), X) -> activate(X)
  , activate(X) -> X
  , activate(n__nil()) -> nil()
  , activate(n____(X1, X2)) -> __(X1, X2)
  , activate(n__isList(X)) -> isList(X)
  , activate(n__isNeList(X)) -> isNeList(X)

Obligation:
  runtime complexity
Answer:
  YES(O(1),O(n^1))

We use the processor 'matrix interpretation of dimension 2' to
orient following rules strictly.

Trs: { __(__(X, Y), Z) -> __(X, __(Y, Z)) }

The induced complexity on above rules (modulo remaining rules) is
YES(?,O(n^1)) . These rules are moved into the corresponding weak
component(s).

Sub-proof:
----------
  The following argument positions are usable:
    Uargs(__) = {2}, Uargs(and) = {1, 2}, Uargs(activate) = {1},
    Uargs(isList) = {1}, Uargs(isNeList) = {1}, Uargs(n____) = {2},
    Uargs(n__isList) = {1}, Uargs(isQid) = {1},
    Uargs(n__isNeList) = {1}, Uargs(isNePal) = {1},
    Uargs(n__isPal) = {1}, Uargs(isPal) = {1}

We return to the main proof.

We are left with following problem, upon which TcT provides the
certificate YES(O(1),O(1)).

Answer:
  YES(O(1),O(1))

Empty rules are trivially bounded

Hurray, we answered YES(O(1),O(n^1))
