【Abstract】 A class of conjugate descent algorithm with single parameter βｋ for unconstrained minimization problems is presented and it is proved that this algorithm is of descent feature when it satisfies the condi- tion of a sort of inexact linear searching and, in addition, it is globally convergent. It can be found, mean- time, that conventional conjugate descent algorithm is a special case of the algorithm presented.更多还原
