Augmented Lagrangian methods can be shown to converge provided that the penalty parameter is sufficiently large and the multiplier estimate is sufficiently close to the optimal multiplier; see, for example, Bertsekas (1982). Here, we extend the penalty estimate from Friedlander and Leyffer (2008) to nonlinear … Skatīt vairāk In practice, many NLPs are not feasible; this situation happens frequently, for example during the resolution of MINLPs. In this case, it is important that the NLP solver quickly and … Skatīt vairāk The filter introduced in Sect. 2 ensures convergence only to feasible limit points; see Lemma 5. Thus, we need an additional … Skatīt vairāk Either the restoration phase converges to a minimum of the constraint violation, or it finds a point x^{(k+1)}that is acceptable to the filter in a finite … Skatīt vairāk The restoration phase minimizes \eta (x)^2 and hence either converges to a local minimum of the constraint violation or generates a sequence of iterates x^{(j)} with \eta (x^{(j)}) \rightarrow 0. Because we only add points … Skatīt vairāk TīmeklisThe Wiener filter is the MSE-optimal stationary linear filter for images degraded by additive noise and blurring. Calculation of the Wiener filter requires the assumption that the signal and noise processes are second-order stationary (in the random process sense). For this description, only noise processes with zero mean will be considered ...
