The useful and classical question of the stability of approximate solutions to a parametrized minimization problem is revisited and examined under various facets. New notions of continuity for functions and multifunctions are involved in this study. Incidentally, a characterization of variational convergence is presented. Some persistence results complete this circular tour.
