| Abstract: | In this paper, a method for generating conjugate directions which is suitable for excution on a parallel computer is presented. Based on this method, a parallel conjugate-direction type method for unconstrained optimization is given. Many numerical results show its efficience with low cost and adaption to many kinds of functions. |
