一种l2,1范数最小化问题的算法研究

摘要

提出一种求解l2,1范数的最小化问题的增广拉格朗日函数法,用以求解最小化问题,算法的收敛性容易实现.数值试验表明,所提出来的算法是可行的.%This paper proposes an augmented Lagrange function method to solve l2,1 - norm minimization problem. The convergence of the algorithm is easily followed in this paper. The numerical experiments illustrate that the proposed algorithm performs quite well.
