However, in practice, there exist conditions where CMA-ES converges to the global optimum (accomplishing its primary goal) while it does not learn the true covariance matrix (missing an auxiliary objective), likely due to step-size defic","authors_text":"Darrell Whitley, Herschel Rabitz, Jonathan Roslund, Ofer M.
