ResQPASS: an algorithm for bounded variable linear least squares with asymptotic Krylov convergence
Bas Symoens, Wim Vanroose
We present the Residual Quadratic Programming Active-Set Subspace (ResQPASS) method that solves large-scale linear least-squares problems with bound constraints on the variables. T…
