When is a gap function good for error bounds?

Joydeep Dutta (jdutta***at***iitk.ac.in)

Abstract: In this paper we survey some important classes of gap function for variational inequalities and also some recently introduced gap functions for generalized variational inequalities. A new gap function is proposed for generalized variational inequalities and error bound is developed. Error bounds are also developed for some particular classes of gap functions. In fact a gap function is useful in devising an error bound if its value on a feasible sequence converging to solution of the variational inequality decreases to zero. We under what conditions the gap functions discussed in this article will follow the above property.
