Rosen法中二次求投影梯度的一种简化方法

A SIMPLE WAY OF WORKING OUT PROJECTI0N GRADIENT TWICE IN ROSEN'S METHOD

用Rosen投影梯度法构造搜索方向经常要两次汁算投影负梯度，对此本文提出一种改进的方法．

Usually only twice we work out the projection gradient by using Rosen's method,can we obtain the search direction.In this paper an improved way is put forward.Abstract Usually only twice we work out the projection gradient by using Rosen's method,can we obtain the search direction.In this paper an improved way is put forward.
