Is GR unique?

Not sure. I will present an iterative Hamiltonian approach, to build up a gravity theory with all constraints being first class and thus possesses only 2 local degrees of freedom. The results are conjectural, rather than conclusive. If it is true, however, it implies GR may not be unique in the 4-dimensional space-time. If time permits, I will also briefly discuss the recently proposed 4D Einstein-Gauss-Bonnet gravity, which was another attempt of mine, yet probably unsuccessful one, along the line.
