A penalized interior point approach for constrained nonlinear programming is examined in this work. To overcome the difficulty of initialization for the interior point method, a problem equivalent to the primal problem via incorporating an auxiliary variable is constructed. A combined approach of logarithm barrier and quadratic penalty function is proposed to solve the problem. Based on Newton's method, the global convergence of interior point and line search algorithm is proven.Only a finite number of iterations is required to reach an approximate optimal solution. Numerical tests are given to show the effectiveness of the method. 相似文献

茶与中国五千年文明史牢固结合在一起,是文明的象征,友谊的桥梁.茶由于自然属性,产生了以茶为载体的茶文化,中国饮茶之久、茶区之广、茶艺之精、名茶之多、品质之好、堪称世界之最,如今饮茶更成为世界性的风尚,作为世界三大健康饮品之一,足迹遍布了整个世界.而各个地区的饮茶习俗、文化又有着争奇斗艳的特色.不同的茶俗,反映了不同民族、地区、国家的不同价值理念和文化取向.用茶文化来打造茶叶驰名品牌,以及借助茶艺来引导茶叶消费、拓展茶叶市场对于中国的经济有很大的发展.本文针对近年中国的茶文化的推广阐述了其存在的主要障碍以及建议. 相似文献
