Under the Wolfe line search, the proposed method can generate a descent direction in each iteration, and the global convergence property can be also guaranteed. Numerical results show that the new method is efficient and stationary  compared to the CD (Fletcher 1987) method, the DY (Dai and Yuan 1999) method, and the SFR (Du and Chen 2008) method; so it can be widely used in scientific computation.<\/jats:p>","DOI":"10.1155\/2012\/569795","type":"journal-article","created":{"date-parts":[[2012,3,26]],"date-time":"2012-03-26T21:15:19Z","timestamp":1332796519000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["A Mixed Spectral CD\u2010DY Conjugate Gradient Method"],"prefix":"10.1155","volume":"2012","author":[{"given":"Liu","family":"Jinkui","sequence":"first","affiliation":[]},{"given":"Du","family":"Xianglin","sequence":"additional","affiliation":[]},{"given":"Wang","family":"Kairong","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2012,3,26]]},"reference":[{"key":"e_1_2_6_1_2","unstructured":"YuG.
