Hybrid limited memory gradient projection methods for box-constrained optimization problems

HIGHLIGHTS

• who: Serena Crisci from the (UNIVERSITY) have published the Article: Hybrid limited memory gradient projection methods for box-constrained optimization problems, in the Journal: (JOURNAL)
• what: In this perspective the authors propose an automatic steplength selection technique that employs a proper alternation of standard Barzilai-Borwein rules when the final active set is not well approximated and a generalized strategy based on the Ritz-like values of the Hessian matrix restricted to the inactive constraints when the final active set is reached. By deepening the results, the authors investigate how to employ, in gradient projection . . .
