WebThe best package I'm aware of for general nonlinear optimization is IPOPT[1]. Apparently Matthew Xu maintains a set of Python bindings to IPOPT, so this might be somewhere to start. UPDATE: the current maintained Python bindings for IPOPT seems to be ipyopt [1]: Andreas Wachter is a personal friend, so I may be a bit biased. WebJun 15, 2013 · To make IPOPT efficient and robust, they add some safeguards in their implementation. One crucial safeguard is to apply the inertia correction technique tomodify theKKTmatrix. We focuson thedegenerateproblems inwhich theKKTmatrixmight be singular. ... On the rate of convergence of the Levenberg–Marquardt method. Computing (Suppl. …
