A class of gap functions for quasi-variational inequality problems
Masao Fukushima · Journal of Industrial and Management Optimization · 2007
We present a class of gap functions for the quasi-variationalinequality problem (QVIP). We show the equivalence between the optimizationreformulation with the gap function and the original QVIP.We also give conditions under which the gap function is continuousand directionally differentiable.
