This paper presents two new preconditioned conjugate gradient algorithms for nonlinear unconstrained optimization problems and examines their computational pcrtormance.

Computational experience shows that the new proposed algorthms generally implone the efficiency of Nazareth’s [13] preconditioned conjugate gradient algorithm.
