| Abstract: | In this paper we present a nonmonotone line search method for solving nonlinear equations with simple bounds.The new method uses inaccuracy line search technique,and uses nonmotone structure which relaxes the conditions that the trial step is accepted.The"max"of function values is replaced by an average of function values.So the new method is more concise and more general.Under the standard assumptions,we prove global convergence for the algorithm.Finally the results of numerical tests show that the new method is very effective. |
