+quadratic programming 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, 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.")
