ON THE CONSTRUCTION OF GAP FUNCTIONS FOR VARIATIONAL INEQUALITIES VIA CONJUGATE DUALITY

ALTANGEREL, LKHAMSUREN; BOŢ, RADU IOAN; WANKA, GERT - In: Asia-Pacific Journal of Operational Research (APJOR) 24 (2007) 03, pp. 353-371

In this paper, we deal with the construction of gap functions for variational inequalities by using an approach which … bases on the conjugate duality. Under certain assumptions we also investigate a further class of gap functions for the … variational inequality problem, the so-called dual gap functions. …

A feasible descent algorithm for solving variational inequality problems

Han, Deren; Lo, Hong K. - In: Computational Statistics 58 (2003) 2, pp. 259-269

In this paper, for solving variational inequality problems (VIPs) we propose a feasible descent algorithm via minimizing the regularized gap function of Fukushima. Under the condition that the underlying mapping of VIP is strongly monotone, the algorithm is globally convergent for any...
