* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          a__c() -> c()
          a__c() -> d()
          a__g(X) -> a__h(X)
          a__g(X) -> g(X)
          a__h(X) -> h(X)
          a__h(d()) -> a__g(c())
          mark(c()) -> a__c()
          mark(d()) -> d()
          mark(g(X)) -> a__g(X)
          mark(h(X)) -> a__h(X)
      - Signature:
          {a__c/0,a__g/1,a__h/1,mark/1} / {c/0,d/0,g/1,h/1}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {a__c,a__g,a__h,mark} and constructors {c,d,g,h}
