%description
Provides an optimization method based on sequential quadratic programming
(SQP) for maximum likelihood estimation of the mixture proportions in a
finite mixture model where the component densities are known. The
algorithm is expected to obtain solutions that are at least as accurate as
the state-of-the-art MOSEK interior-point solver (called by function
"KWDual" in the 'REBayes' package), and they are expected to arrive at
solutions more quickly when the number of samples is large and the number
of mixture components is not too large. This implements the "mix-SQP"
algorithm, with some improvements, described in Y. Kim, P. Carbonetto, M.
Stephens & M. Anitescu (2020) <DOI:10.1080/10618600.2019.1689985>.
