The performance of Stiefel's conjugate gradient (CG) method and a reformulated three-parameter C G are compared for structural analysis problems having varying condition numbers. It has been found that diagonal preconditioning in the three-parameter C G method is efficient when high condition number

In this paper we develop a new class of conjugate gradient methods for unconstrained optimization problems. A new nonmonotone line search technique is proposed to guarantee the global convergence of these conjugate gradient methods under some mild conditions. In particular, Polak-RibiΓ©re-Polyak and
