ЧТО ОЗНАЧАЕТ СЛОВО BARRIER METHOD
Метод внутренней точки
Методы внутренних точек - это определенный класс алгоритмов для решения задач линейной и нелинейной выпуклой оптимизации. Примерное решение Метод внутренней точки был изобретен Джоном фон Нейманом. Фон Нейман предложил новый метод линейного программирования, используя однородную линейную систему Гордана, которая позже была популяризирована алгоритмом Кармаркара, разработанная Нарендра Кармаркар в 1984 году для линейного программирования. Метод состоит из самосогласованной барьерной функции, используемой для кодирования выпуклого множества. В отличие от симплексного метода, он достигает оптимального решения, пересекая внутренность допустимой области. Любая выпуклая задача оптимизации может быть преобразована в минимизацию линейной функции над выпуклым множеством путем преобразования в форму эпиграфа. Идея кодирования допустимого набора с использованием барьера и разработки барьерных методов была изучена Энтони В. Фиако, Гартом П. Маккормиком и другими в начале 1960-х годов. Эти идеи были в основном разработаны для общего нелинейного программирования, но позже они были оставлены из-за наличия более конкурентоспособных методов для этого класса проблем.

The lenticular sheet method evolved from the parallax barrier method [16.9,

eyes ...

No ipm's have proven complexity bounds which are better than (2.18) even in the

Primal- dual interior-point methods are very similar to the barrier method, with
some differences. • There is only one loop or iteration, i.e., there is no distinction
