Input Problem:    innermost runtime-complexity with respect to
  Rules:
    {  active(__(__(X, Y), Z)) -> mark(__(X, __(Y, Z)))

Details:         
  We have computed the following set of weak (innermost) dependency pairs:
   {  active^#(__(__(X, Y), Z)) -> c_0(__^#(X, __(Y, Z)))
    , active^#(__(X, nil())) -> c_1()
    , active^#(__(nil(), X)) -> c_2()
    , active^#(U11(tt())) -> c_3(U12^#(tt()))
    , active^#(U12(tt())) -> c_4()
    , active^#(isNePal(__(I, __(P, I)))) -> c_5(U11^#(tt()))
    , active^#(__(X1, X2)) -> c_6(__^#(active(X1), X2))
    , active^#(__(X1, X2)) -> c_7(__^#(X1, active(X2)))

    , active^#(isNePal(X)) -> c_10(isNePal^#(active(X)))
    , __^#(mark(X1), X2) -> c_11(__^#(X1, X2))
    , __^#(X1, mark(X2)) -> c_12(__^#(X1, X2))
    , U11^#(mark(X)) -> c_13(U11^#(X))
    , U12^#(mark(X)) -> c_14(U12^#(X))
    , isNePal^#(mark(X)) -> c_15(isNePal^#(X))
    , proper^#(__(X1, X2)) -> c_16(__^#(proper(X1), proper(X2)))
    , proper^#(nil()) -> c_17()

    , top^#(mark(X)) -> c_26(top^#(proper(X)))
    , top^#(ok(X)) -> c_27(top^#(active(X)))}
  
  The usable rules are:
   {  active(__(__(X, Y), Z)) -> mark(__(X, __(Y, Z)))
    , active(__(X, nil())) -> mark(X)
    , active(__(nil(), X)) -> mark(X)

    , active(__(X1, X2)) -> __(X1, active(X2))
    , active(U11(X)) -> U11(active(X))
    , active(U12(X)) -> U12(active(X))
    , active(isNePal(X)) -> isNePal(active(X))
    , __(mark(X1), X2) -> mark(__(X1, X2))

    , U11(mark(X)) -> mark(U11(X))

    , U11(ok(X)) -> ok(U11(X))
    , U12(ok(X)) -> ok(U12(X))
    , isNePal(ok(X)) -> ok(isNePal(X))}

   {active^#(__(__(X, Y), Z)) -> c_0(__^#(X, __(Y, Z)))}
     ==> {__^#(ok(X1), ok(X2)) -> c_22(__^#(X1, X2))}

  We consider the following path(s):

       , __^#(mark(X1), X2) -> c_11(__^#(X1, X2))}
      
      The usable rules for this path are the following:
      {  active(__(__(X, Y), Z)) -> mark(__(X, __(Y, Z)))
       , active(__(X, nil())) -> mark(X)
       , active(__(nil(), X)) -> mark(X)

        We have applied the subprocessor on the union of usable rules and weak (innermost) dependency pairs.

                The problem is Match-bounded by 0.
                The enriched problem is compatible with the following automaton:

      The usable rules for this path are the following:

        We have applied the subprocessor on the union of usable rules and weak (innermost) dependency pairs.

                The problem is Match-bounded by 0.
                The enriched problem is compatible with the following automaton:
                {  mark_0(3) -> 3
                 , mark_0(4) -> 3
                 , mark_0(6) -> 3

                 , tt_0() -> 6
                 , ok_0(3) -> 10
                 , ok_0(4) -> 10
                 , ok_0(6) -> 10

   8) {active^#(__(X1, X2)) -> c_7(__^#(X1, active(X2)))}
      
      The usable rules for this path are the following:
      {  active(__(__(X, Y), Z)) -> mark(__(X, __(Y, Z)))
       , active(__(X, nil())) -> mark(X)
       , active(__(nil(), X)) -> mark(X)
       , active(U11(tt())) -> mark(U12(tt()))
       , active(U12(tt())) -> mark(tt())
       , active(isNePal(__(I, __(P, I)))) -> mark(U11(tt()))
       , active(__(X1, X2)) -> __(active(X1), X2)
       , active(__(X1, X2)) -> __(X1, active(X2))
       , active(U11(X)) -> U11(active(X))
       , active(U12(X)) -> U12(active(X))
       , active(isNePal(X)) -> isNePal(active(X))
       , __(mark(X1), X2) -> mark(__(X1, X2))
       , __(X1, mark(X2)) -> mark(__(X1, X2))
       , __(ok(X1), ok(X2)) -> ok(__(X1, X2))
       , U11(mark(X)) -> mark(U11(X))
       , U12(mark(X)) -> mark(U12(X))
       , isNePal(mark(X)) -> mark(isNePal(X))
       , U11(ok(X)) -> ok(U11(X))
       , U12(ok(X)) -> ok(U12(X))
       , isNePal(ok(X)) -> ok(isNePal(X))}
      
        We have applied the subprocessor on the union of usable rules and weak (innermost) dependency pairs.

                The enriched problem is compatible with the following automaton:

      The usable rules for this path are the following:

      The usable rules for this path are the following:
      {  proper(__(X1, X2)) -> __(proper(X1), proper(X2))
       , proper(nil()) -> ok(nil())
       , proper(U11(X)) -> U11(proper(X))
       , proper(tt()) -> ok(tt())
       , proper(U12(X)) -> U12(proper(X))
       , proper(isNePal(X)) -> isNePal(proper(X))
       , __(mark(X1), X2) -> mark(__(X1, X2))
       , __(X1, mark(X2)) -> mark(__(X1, X2))
       , __(ok(X1), ok(X2)) -> ok(__(X1, X2))
       , U11(mark(X)) -> mark(U11(X))
       , U12(mark(X)) -> mark(U12(X))
       , isNePal(mark(X)) -> mark(isNePal(X))

       , U12(ok(X)) -> ok(U12(X))
       , isNePal(ok(X)) -> ok(isNePal(X))}
      
        We have applied the subprocessor on the union of usable rules and weak (innermost) dependency pairs.

              Details:         
                The problem is Match-bounded by 0.
                The enriched problem is compatible with the following automaton:
                {  mark_0(2) -> 2
                 , nil_0() -> 2
                 , tt_0() -> 2
                 , ok_0(2) -> 2
                 , __^#_0(2, 2) -> 1
                 , c_11_0(1) -> 1
                 , c_12_0(1) -> 1
                 , proper^#_0(2) -> 1
                 , c_22_0(1) -> 1}
      
   16)
      {proper^#(U11(X)) -> c_18(U11^#(proper(X)))}
      
      The usable rules for this path are the following:
      {  proper(__(X1, X2)) -> __(proper(X1), proper(X2))
       , proper(nil()) -> ok(nil())
       , proper(U11(X)) -> U11(proper(X))
       , proper(tt()) -> ok(tt())
       , proper(U12(X)) -> U12(proper(X))
       , proper(isNePal(X)) -> isNePal(proper(X))
       , __(mark(X1), X2) -> mark(__(X1, X2))
       , __(X1, mark(X2)) -> mark(__(X1, X2))
       , __(ok(X1), ok(X2)) -> ok(__(X1, X2))
       , U11(mark(X)) -> mark(U11(X))
       , U12(mark(X)) -> mark(U12(X))
       , isNePal(mark(X)) -> mark(isNePal(X))
       , U11(ok(X)) -> ok(U11(X))
       , U12(ok(X)) -> ok(U12(X))
       , isNePal(ok(X)) -> ok(isNePal(X))}
      
        We have applied the subprocessor on the union of usable rules and weak (innermost) dependency pairs.

                The problem is Match-bounded by 0.
                The enriched problem is compatible with the following automaton:

      The usable rules for this path are the following:

        We have applied the subprocessor on the union of usable rules and weak (innermost) dependency pairs.

      The usable rules for this path are the following:

        We have applied the subprocessor on the union of usable rules and weak (innermost) dependency pairs.
