Accession number: 20154201388982 Title: A two-term fletcher-reeves conjugate gradient method for monotone constrained equations and its application in compressive sensing Authors: Sun, Xiaoli1 Email author xiaolisunzaozhuang@126.com Author affiliation: 1 School of Mathematics and Statistics, Zaozhuang University, No. 1, Beian Road, Zaozhuang, China Corresponding author: Sun, Xiaoli Source title: ICIC Express Letters Abbreviated source title: ICIC Express Lett. Volume: 9 Issue: 11 Issue date: November 1, 2015 Publication year: 2015 Pages: 2987-2992 Language: English ISSN: 1881803X Document type: Journal article (JA) Publisher: ICIC Express Letters Office Abstract: In this paper, a two-term Fletcher-Reeves conjugate gradient method is proposed for monotone constrained equations, which combines a recently modified Fletcher- Reeves (FR) conjugate gradient method and the famous projection method. A prominent character of the method is that it is globally convergent without requiring the restart procedure, which maybe enhance its efficiency. The numerical results reported in this paper illustrate that the proposed method is efficient for compressive sensing. © 2015 ICIC International.
