This algorithm achieves an approximation ratio of (1e1ln12ln1)(1e1ln12ln1) with O(d2)O(d2) iterations and O(N2/3d3/23)O(N2/3d3/23) oracle calls. We also extend m{\\bf{NZOSA}} to handle a class of robust DR-submodular maximization problems. To validate the effectiveness of our...

a series of analytical work was conducted to provide theoretical interpretation and performance guarantees. These analyses focus on the accuracy of derivative approximation techniques such as polynomial interpolation, as well as the behavior of the trust-region method...
Using the zeroth approximation, the defining equations for order are obtained. The transformation temperature consequences of the calculation are employed in evaluating experimental data and a revised version of the Fe Al phase diagram is arrived at. It is shown that for compositions greater than 25...
In this paper, we propose and analyze zeroth-order stochastic approximation algorithms for nonconvex and convex optimization, with a focus on addressing constrained optimization, high-dimensional setting, and saddle point avoiding. To handle constrained optimization, we first propose generalizations of the...
where\(r_0\)and\(\omega _0\)are positive real parameters denoting the radius of the bright vortex ring and the ring width, respectively (see Fig.1(a1,a2)). When\(r_0 \gg \omega _0\), the last exponent in Eq. (6) can be viewed as an approximation of the modified Bessel funct...

This equation is considered as a zeroth-order approximation in the calculation of the corrections to the energy levels. This is the Breit equation that takes into account additional small terms (with respect to the parameter ( Z伪 ) 2 ). A procedure that employs the Brillouin-Wigner ...
zeroth order approximation/ A6170B Interstitials and vacancies A6630F Self-diffusion in solid metals, semimetals, and alloysThe energy of movement, of cations and anions, via single vacancies and vacancy pairs in some alkali halides have been calculated. The results of these calculations, in the ...
