This paper presents a new proof method about the paper (Yuan et al. in Appl. Math. Model. 47:811-825, 2017). In the proof, the global convergence of the Polak-Ribière-Polak algorithm is established without these two assumptions d T k g k < 0 and g k+1 d k ≤ -σ 1 g T k d k which are needed in the above paper. This means that this paper has the same results under weaker conditions. More dimension functions for practical problems are tested to show the performance of the modified algorithm and the
more » ... normal algorithm. An application of the fact engineering model is done to show the effectiveness of the given conjugate gradient algorithm. MSC: 90C26
