In this paper we develop new primal-dual interior-point methods for linear programming, which are based on the concept of parabolic target space. We show that such schemes work in the infinity-neighborhood of the primal-dual central path. Nevertheless these methods possess the best known...

The restructuring of electric systems can follow different paradigms that have different impacts. The objective of this paper is to show that Variational Inequalities Problems provide a natural tool for modeling electricity restructuring in a wide range of relevant situations.
