摘要 提出了投影算子的一种Halpern型的松弛算法,由于这种算法把计算关于一个凸函数水平集的投影转化为计算关于一列包含水平集的半空间的投影,因而算法容易实现,并且证明了算法的强收敛性。 A relaxed Halpem's projection algorithm is proposed.Since this algorithm computes the projection onto level set of a convex function by computing the projection onto a series of half-spaces containing a level set,it is easy to be implemented.Strong convergence of this algorithm is proved.
