In this paper, we study an augmented Lagrangian-type algorithm called the Dislocation Hyperbolic Augmented Lagrangian Algorithm (DHALA), which solves an inequality nonconvex optimization problem. We show that the sequence generated by DHALA converges

The dislocation hyperbolic augmented Lagrangian algorithm (DHALA) is a new approach to the hyperbolic augmented Lagrangian algorithm (HALA). DHALA is designed to solve convex nonlinear programming problems. We guarantee that the sequence generated by

In this work, Rn we present an efficient strongly polynomial algorithm for the projection of a point on the intersection of two hyperplanes and a box in Rn. Interior point methods are the most efficient algorithm in the literature to solve this probl
