* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          active(b()) -> mark(c())
          active(f(X,g(X),Y)) -> mark(f(Y,Y,Y))
          active(g(X)) -> g(active(X))
          active(g(b())) -> mark(c())
          f(ok(X1),ok(X2),ok(X3)) -> ok(f(X1,X2,X3))
          g(mark(X)) -> mark(g(X))
          g(ok(X)) -> ok(g(X))
          proper(b()) -> ok(b())
          proper(c()) -> ok(c())
          proper(f(X1,X2,X3)) -> f(proper(X1),proper(X2),proper(X3))
          proper(g(X)) -> g(proper(X))
          top(mark(X)) -> top(proper(X))
          top(ok(X)) -> top(active(X))
      - Signature:
          {active/1,f/3,g/1,proper/1,top/1} / {b/0,c/0,mark/1,ok/1}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {active,f,g,proper,top} and constructors {b,c,mark,ok}
