WebBlock principal pivoting algorithms allow the sets of basic and nonbasic variables to change in more than one element and seem much more suited for this type of problem. … WebOur algorithm is based on al-ternating nonnegativity-constrained least squares (ANLS) framework, where in each iteration the nonnegativity-constrained least squares (NNLS) sub-problems are solved. We propose to solve the NNLS problems based on the block principal pivoting method [12]. The block principal pivoting method
WebThe main computational effort of ADMM is the solution of a Strictly Convex StQP, which can be efficiently solved by a Block Principal Pivoting algorithm. Furthermore, this algorithm provides a stopping criterion for ADMM that improves very much its efficacy to compute an accurate solution of the EiCP.
