Nettet2. feb. 2024 · linear convergence rate for BPPA has yet been thoroughly studied in the literature. In this paper, we an-alyze the linear convergence rate of BPPA. Under the assumption that the objective function is strongly convex relative to a Legendre function, we establish the linear convergence for the function values se-quence. NettetWe study the linear convergence of variants of the Frank-Wolfe algorithms for some classes of strongly convex problems, using only afﬁne-invariant quantities. As in [GM86], we show the linear convergenceof the standard Frank-Wolfe algo-rithm when the solution is in the interior of the domain, but with afﬁne invariant constants.

NettetThis rate is referred to as \sub-linear convergence." Strongly convex f. In contrast, if we assume that fis strongly convex, we can show that gradient descent converges with rate O(ck) for 0 <1. This means that a bound of f(x(k)) f(x) can be achieved using only O(log(1= )) iterations. This rate is typically called \linear convergence."

Nettet22. jan. 2024 · In Wiki page, the sublinear convergence rate refers that for a sequence { x k } with limit L , lim sup ‖ x k + 1 − L ‖ ‖ x k − L ‖ = 1. In most convex optimization books, a sequence converges at a rate O ( 1 / k) also referred as sublinear. I am a little bit confused on the exact meaning of sublinear rate.

Nettet21. jun. 2024 · Usually, linear convergence of distributed ADMM is proved under either second-order conditions or strong convexity. When both conditions fail, an alternative is expected to play the role. In this article, it is shown that distributed ADMM can achieve a linear convergence rate by imposing metric subregularity on a defined mapping.

Nettet$\begingroup$ @Fractal20 The thing is, as a practical matter, as I said in the end of my answer, monotonic convergence, or even asymptotically monotonic convergence, tends to be hopeless. We tend to have fluke iterations where things are better than they "should" be, no matter what exactly we are doing. (There are some exceptions, for example … NettetStationary (time-invariant) models with nonlinearities may converge very slowly. A nonlinearity can be introduced into the model either in the governing equation, or by making any of the material properties, loads, or boundary conditions dependent upon the solution. Multiphysics problems are often nonlinear. If instead the model is linear, see ...
