报告题目    Conjugate Gradient Method without Line Search

Abstract: As we know, conjugate gradient method for unconstrained optimization problem is an efficient method in optimization fields. Line Search in this method is necessary in many situations. This certainly adds the amount of computation. In order to avoid line search in conjugate gradient method, we propose an efficient algorithm without line search by combining trust region method. The new method not only has global convergence theoretically but also has excellent performance in practical computation.
