WORST_CASE(Omega(n^1),O(n^1))
* Step 1: Sum WORST_CASE(Omega(n^1),O(n^1))
    + Considered Problem:
        - Strict TRS:
            rev(++(x,x)) -> rev(x)
            rev(++(x,y)) -> ++(rev(y),rev(x))
            rev(a()) -> a()
            rev(b()) -> b()
        - Signature:
            {rev/1} / {++/2,a/0,b/0}
        - Obligation:
             runtime complexity wrt. defined symbols {rev} and constructors {++,a,b}
    + Applied Processor:
        Sum {left = someStrategy, right = someStrategy}
    + Details:
        ()
** Step 1.a:1: DecreasingLoops WORST_CASE(Omega(n^1),?)
    + Considered Problem:
        - Strict TRS:
            rev(++(x,x)) -> rev(x)
            rev(++(x,y)) -> ++(rev(y),rev(x))
            rev(a()) -> a()
            rev(b()) -> b()
        - Signature:
            {rev/1} / {++/2,a/0,b/0}
        - Obligation:
             runtime complexity wrt. defined symbols {rev} and constructors {++,a,b}
    + Applied Processor:
        DecreasingLoops {bound = AnyLoop, narrow = 10}
    + Details:
        The system has following decreasing Loops:
          rev(y){y -> ++(x,y)} =
            rev(++(x,y)) ->^+ ++(rev(y),rev(x))
              = C[rev(y) = rev(y){}]

** Step 1.b:1: ToInnermost WORST_CASE(?,O(n^1))
    + Considered Problem:
        - Strict TRS:
            rev(++(x,x)) -> rev(x)
            rev(++(x,y)) -> ++(rev(y),rev(x))
            rev(a()) -> a()
            rev(b()) -> b()
        - Signature:
            {rev/1} / {++/2,a/0,b/0}
        - Obligation:
             runtime complexity wrt. defined symbols {rev} and constructors {++,a,b}
    + Applied Processor:
        ToInnermost
    + Details:
        switch to innermost, as the system is overlay and right linear and does not contain weak rules
** Step 1.b:2: Bounds WORST_CASE(?,O(n^1))
    + Considered Problem:
        - Strict TRS:
            rev(++(x,x)) -> rev(x)
            rev(++(x,y)) -> ++(rev(y),rev(x))
            rev(a()) -> a()
            rev(b()) -> b()
        - Signature:
            {rev/1} / {++/2,a/0,b/0}
        - Obligation:
            innermost runtime complexity wrt. defined symbols {rev} and constructors {++,a,b}
    + Applied Processor:
        Bounds {initialAutomaton = minimal, enrichment = match}
    + Details:
        The problem is match-bounded by 1.
        The enriched problem is compatible with follwoing automaton.
          ++_0(2,2) -> 2
          ++_1(1,1) -> 1
          a_0() -> 2
          a_1() -> 1
          b_0() -> 2
          b_1() -> 1
          rev_0(2) -> 1
          rev_1(2) -> 1
** Step 1.b:3: EmptyProcessor WORST_CASE(?,O(1))
    + Considered Problem:
        - Weak TRS:
            rev(++(x,x)) -> rev(x)
            rev(++(x,y)) -> ++(rev(y),rev(x))
            rev(a()) -> a()
            rev(b()) -> b()
        - Signature:
            {rev/1} / {++/2,a/0,b/0}
        - Obligation:
            innermost runtime complexity wrt. defined symbols {rev} and constructors {++,a,b}
    + Applied Processor:
        EmptyProcessor
    + Details:
        The problem is already closed. The intended complexity is O(1).
