Based on an eigenvalue analysis, a new proof for the sufficient descent property of the modified Polak-Ribière-Polyak conjugate gradient method proposed by Yu et al. is presented.
A modified Polak-Ribière-Polyak conjugate gradient algorithm which satisfies both the sufficient descent condition and the conjugacy condition is presented. These properties are independent of the line search. The algorithms use the standard Wolfe line search. Under standard assumptions we show the global convergence of the algorithm. Numerical comparisons with conjugate gradient algorithms usi...
A scheme|inspired from an old idea due to Mayne and Polak (Math. Prog., vol. 11, 1976, pp. 67{80)|is proposed for extending to general smooth constrained optimization problems a previously proposed feasible interior-point method for inequality constrained problems. It is shown that the primal-dual interior point framework allows for a signi cantly more e ective implementation of the Mayne-Polak...
Opowiadanie Jeleny Makarowej – pisarki, dziennikarki, pedagożki, arteterapeutki, kuratorki wystaw, członkini Międzynarodowego PEN Clubu, która w 1990 roku opuściła ZSRR, przenosząc się do Izraela, gdzie mieszka dziś. W błyskotliwy, przewrotny, oparty na osobistym doświadczeniu, sposób Makarowa odsłania kulisy (nie)radzenia sobie społeczeństwa radzieckiego skali mikro z nagłą zmianą narracji, kr...
