In this chapter, we point out that the armijo - type line search will make the step k very small even close to zero in some cases, which leads to the pathological problem
在本章中，我們指出採用armijo型的線搜索，在某些情況下易使步長變的很小，甚至趨于零，這將在計算過程中導致病態現象。 -
Observing that the newton direction is always a descent direction of the square norm of the gradient, even if it is not a descent direction of the objective function, which will result some linear research - such as armijo research or wolfe research - fail
因此，該演算法是頗受歡迎的演算法之一。然而，若問題的目標函數的hessian陣不正定，則不能保證演算法產生的方向是目標函數的下降方向。
