“…Tang, Liu, Jian, and Li have also proposed in [TLJL14] a feasible variant of the SQP-GS method in which the iterates are forced to remain feasible for the constraints and the objective function is monotonically decreasing throughout the optimization process. This opens the door to employing a two-phase approach common for solving some optimization problems, where phase 1 is responsible for attaining a feasible point and phase 2 seeks optimality while maintaining feasibility.…”

“…We also note that our method is very different from that in [16] due to the proximalprojection strategy and the new descent test criterion. Some other recent methods for general-purpose nonsmooth constrained minimization problems can be found in, e.g., [13,32,17,35,36].…”

“…We would like to inspect the reduction of the model function m after we have obtained a new trial point via the linear programming problem (26). Denote a general optimal solution of problem (26) by (x * , z * ) and by (x kl , z kl ) when it is necessary to indicate it is in the l-th minor iteration in the k-th major iteration. In the following lemma we derive the explicit expression of the reduction of the model fromx to x * .…”

“…We will use the following set which essentially defines the model m(x). (25), 'a' be such that E i ≥ 0, ∀ i ∈ I, x * be the first component of an optimal solution of problem (26), and F be defined in (42).…”
