conjugate gradient method

by wenjun luo

This dataset contains data used for the article "Two modified adaptive parameter conjugate gradient methods for unconstrained optimization" Wenjun Luo, and Zezhong Wu.

MDYHS.csv and MDYHSCD.csv correspond to the MDYHS method and MDYHS method in the first class of methods proposed in this paper respectively.

CSDCG(O=1).csv, CSDCG(O=gg).csv, CSDCG(O=-sg).csv, and CSDCG(O=sy).csv respectively correspond to the cases of O=1, O=gg, O=-sg, and O=sy of the second method proposed in this paper.

ACGSSV.csv, ADHCG.csv, ADHCG.csv, and NACGM.csv are other CG methods for comparison.
