      Description

      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.
