Within the holographic cosmology paradigm, specifically the model of McFadden
and Skenderis, but more generally than that, the cosmological constant is found
to naturally flow from a large value, to a small value, which can even be as
low as the needed
$sim 10^{-120}$ times the original, along with the dual RG flow. Within this
context then, the cosmological constant problem is mapped to a simple quantum
field theory property, even though the exact mechanism for it in gravity is
still obscure. I consider several examples of gravity duals to explain the
mechanism.
