Модифицированный метод Хука-Дживса Модифицированный метод Хука-Дживса Этот метод нетрудно модифицировать и для учета ограничений .Было выдвинуто предложение , что для этого будет вполне достаточно при решении задачи минимизации присвоить целевой функции очень большое значение там,где ограничения нарушаются .К тому же такую идею просто реализовать с помощью програмирования . Нужно проверить ,каждая ли точка ,полученная в процессе поиска , принадлежит области ограничений .Если каждая , то целевая функция вычисляется обычным путем . Если нет , то целевой функции присваивается очень большое значение . Таким образом , поиск будет осуществляться снова в допустимой области в направлении к минимальной точке внутри этой области. В тексте прогаммы модифицированного метода прямого поиска Хука-Дживса сделана попытка реализовать такую процедуру. Рассматриваемая задача формулируется следующим образом : минимизировать f (x1,x2) = 3x12 4x1x2 5x22 , при ограничениях x1.
