> {{alpha}} is provided as an alias to {{docConcentration}} because it is commonly used
in literature. However, we should prefer {{docConcentration}} since it is unambiguous what
we mean.
> The public API currently uses {{ {get,set}OptimizeAlpha}} but should instead use {{ {get,set}OptimizeDocConcentration}}.
We should also probably deprecate any public API's using {{alpha}} directly and refer users
to the corresponding {{docConcentration}} methods.
