Optim. 8, No.1, 158-186 (1998).} \itemab Summary: A new algorithm for large-scale nonlinear programs with box constraints is introduced. The algorithm is based on an efficient identification technique of the active set at the solution and on a nonmonotone stabilization technique. It possesses global and superlinear convergence properties under standard assumptions. A new technique for generating test problems with known characteristics is also introduced. The implementation of the method is described along with computational results for large-scale problems. \itemrv{~} \itemcc{} \itemut{Newton's method; box constraints; large-scale problems; active set; global and superlinear convergence} \itemli{doi:10.1137/S1052623493253991} \end
