We present a brief survey of the current state of the art in network reliability. We survey only exact methods and do not consider Monte Carlo methods. Most network reliability problems are, in the worst case, NP-hard and are, in a sense, more difficult than many standard combinatorial optimization problems. Nevertheless, there are, in fact, linear and polynomial time algorithms for network reliability problems of special structure.

Monte Carlo method

Monte Carlo methods , or Monte Carlo experiments , are a broad class of computational algorithms that rely on repeated random sampling to obtain numerical results. The underlying concept is to use randomness to solve problems that might be deterministic in principle. They are often used in physical and mathematical problems and are most useful when it is difficult or impossible to use other approaches. Monte Carlo methods are mainly used in three problem classes: [1] optimization , numerical integration , and generating draws from a probability distribution. In physics-related problems, Monte Carlo methods are useful for simulating systems with many coupled degrees of freedom , such as fluids, disordered materials, strongly coupled solids, and cellular structures see cellular Potts model , interacting particle systems , McKean—Vlasov processes , kinetic models of gases. Other examples include modeling phenomena with significant uncertainty in inputs such as the calculation of risk in business and, in mathematics, evaluation of multidimensional definite integrals with complicated boundary conditions.

This is going to win you a lot of friends and a lot of respect around here, Jeff. Folks will remember it for a long time. He peered over the front edge and found McDaniel about finished with the painting. Marissa took the good with the bad. Entry was obtained through a series of sliding steel doors activated by remote control. Then, with an embarrassed expression on her face, she backed away, pushing her hair out of her tear streaked face.

Reliability analysis and improvement of multilevel converters. Doctoral thesis, Nanyang Technological University, Singapore. It can reduce the operating cost of motor drive system significantly. However, the reliability of power converter is a salient concern for both manufacturers and end users as high failure rate will incur additional repairing cost. In high power drive applications, multilevel converters which utilize mature power semiconductors are superior to conventional two-level converters in efficiency and power quality.

A Survey of Network Reliability and Domination Theory

The system can't perform the operation now. Try again later. Citations per year.

Consider a network of unreliable links, modelling for example a communication network. Estimating the reliability of the network—expressed as the probability that certain nodes in the network are connected—is a computationally difficult task. In this paper we study how the Cross-Entropy method can be used to obtain more efficient network reliability estimation procedures. We show that the Cross-Entropy method yields a speed-up over all three techniques.

The Cross-Entropy Method for Network Reliability Estimation

Он писал алгоритмы и зарабатывал неплохие деньги. Как и большинство талантливых программистов, Танкада сделался объектом настойчивого внимания со стороны АНБ.

Собрав все силы, Хейл, сильнее обхватив Сьюзан за талию, начал пятясь подниматься по лестнице. Она пыталась цепляться каблуками за ступеньки, чтобы помешать ему, но все было бесполезно. Он был гораздо сильнее, и ему легче было бы подталкивать ее вверх, тем более что площадка подсвечивалась мерцанием мониторов в кабинете Стратмора. Но если она окажется впереди, он подставит Стратмору спину. Волоча Сьюзан за собой, он использовал ее как живой щит.

Наверное, за ним тянется красный след на белых камнях. Он искал глазами открытую дверь или ворота - любой выход из этого бесконечного каньона, - но ничего не. Улочка начала сужаться. - Soccoro! - Его голос звучал еле слышно.  - Помогите. С обеих сторон на него надвигались стены извивающейся улочки. Беккер искал какой-нибудь перекресток, любой выход, но с обеих сторон были только запертые двери.

 - На это уйдет полчаса. К тому времени все уже рухнет. Джабба открыл рот, готовый что-то сказать, но тут его буквально парализовал душераздирающий крик. Все повернули головы к Сьюзан Флетчер, которая выпрямилась и поднялась со стула. Лицо ее побелело, глаза не отрываясь смотрели на застывший кадр, демонстрировавший неподвижное тело Дэвида Беккера, залитое кровью, брошенное на пол мини-автобуса. - Вы его убили! - крикнула .

Все люди умирают… что значит еще одна смерть. ГЛАВА 91 В соборе всегда ночь. Тепло дня здесь сменяется влажной прохладой, а шум улицы приглушается мощными каменными стенами.

Получалось, что АНБ фактически получило возможность вскрывать всю почту и затем пересылать ее без какого-либо уведомления.
