Abstract: |
A new nonmonotone line search for the WYL conjugate gradient method is presented.The nonmonotone line search can guarantee the global convergence of WYL method.Numerical experiments show that WYL method with the nonmonotone line search is more available than Armijo method. |
Key words: conjugate gradient method line search global convergence |
