MAYBE
* Step 1: DependencyPairs MAYBE
    + Considered Problem:
        - Strict TRS:
            f(a()) -> f(a())
        - Signature:
            {f/1} / {a/0}
        - Obligation:
            innermost runtime complexity wrt. defined symbols {f} and constructors {a}
    + Applied Processor:
        DependencyPairs {dpKind_ = DT}
    + Details:
        We add the following dependency tuples:
        
        Strict DPs
          f#(a()) -> c_1(f#(a()))
        Weak DPs
          
        
        and mark the set of starting terms.
* Step 2: UsableRules MAYBE
    + Considered Problem:
        - Strict DPs:
            f#(a()) -> c_1(f#(a()))
        - Weak TRS:
            f(a()) -> f(a())
        - Signature:
            {f/1,f#/1} / {a/0,c_1/1}
        - Obligation:
            innermost runtime complexity wrt. defined symbols {f#} and constructors {a}
    + Applied Processor:
        UsableRules
    + Details:
        We replace rewrite rules by usable rules:
          f#(a()) -> c_1(f#(a()))
* Step 3: Failure MAYBE
  + Considered Problem:
      - Strict DPs:
          f#(a()) -> c_1(f#(a()))
      - Signature:
          {f/1,f#/1} / {a/0,c_1/1}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {f#} and constructors {a}
  + Applied Processor:
      EmptyProcessor
  + Details:
      The problem is still open.
