“…Among all extensions and variants of APM, it is worth mentioning that Dykstra and Boyle [21], [5] found a suitable modification of von Neumann's scheme for closed and convex sets. APM and their variants have been used by many researches to solve problems on a wide variety of applications [4,6,10,22,23,27,29,32,35,36,38].…”

“…The formulation of this problem is to find the least squares solution of the matrix equation AX = B, where A, B ∈ R m×n are given, the fitting matrix X ∈ R n×n is a symmetric and bounded matrix, and the smallest eigenvalue is no less than a specified positive number since, in the neighborhood of equilibrium, the approximate of the utility function is a quadratic and strictly concave with Hessian matrix. Other examples discussed in [27] and [28] are respectively to find a symmetric positive definite patterned matrix closest to a sample covariance matrix and to find a symmetric and diagonally dominant matrices with positive diagonal matrix closest to a given matrix.…”

“…Criteria for the selection of the supporting hyperplanes of the active faces have been proposed in [32] to improve the convergence rate. As for the computational complexity The sequence of projections between the set of symmetric and the set of diagonally dominant matrices in Algorithm 1.…”
