Erratum to: 'Comments on another hybrid conjugate gradient algorithm for unconstrained optimization by Andrei'

We would like to correct some details of the above paper. According to References [1] and formula (2.8) in the above paper, we give some corrections about the above paper. More precisely, • The formula (2.9) in Theorem 2.1 should be g k+1dk+1 ≤ −δ‖gk+1‖. • Formula (3.1) should be g k sk ≤ −δ‖gk‖. • Formula (3.2) should be g k dk ≤ −δ‖gk‖. • Formula (3.3) should be g k sk ≤ −αkδ‖gk‖. • Formula (3.9) should be g k sk ≤ −αkδ‖gk‖.
