A New Type of Hybrid Conjugate Gradient Methods
Abstract
The paper puts forward a new conjugate gradient method βk and discusses its properties. Then,based on a new formula,the author proposes a new type of hybrid conjugate gradient method,which retains a sufficiently descent direction without utilizing the line search. Under the weak Wolfe-Powell line search,the method proves to be globally convergent. Numerical results show that the new method performs much better than both HZ and PRP...
