RcppEnsmallen package brings to R a Header-Only C++ Mathematical
Optimization Library for Armadillo.
In particular, Ensmallen is a
templated C++ mathematical optimization library (by the MLPACK team) that provides a simple set of abstractions for writing an
objective function to optimize.
Well, CRAN was on
when the Ensmallen Development Team
released this version. So, there was a slight delay in getting it listed on
CRAN. Within the new version, there is a new optimizer
LBestPSO that was
in the works for awhile now (~February 2019). Moreover, there was an API change
related to adding an option to avoid computing the
exact objective function value at the end of the optimization routine. There
gcc diagnostic message that was also addressed related to types.
