Solving Asymmetric Variational Inequalities via Convex Optimization

Using duality, we reformulate the asymmetric variational inequality (VI) problem over a conic region as an optimization problem.

Robust Game Theory

Classical game theory, which is useful in understanding market behavior, relies on what have been described as four “essential elements” — who is playing, how much information they possess, the actions available to them, and the payoffs for each outcome. In this paper, we propose a model of games in which players have incomplete information, and we offer ideas on how to optimize outcomes.

Robust Optimization, Game Theory and Variational Inequalities

We propose a robust optimization approach to analyzing three equilibrium problems: the nominal variational inequality (VI) problem over a polyhedron, the finite game under payoff uncertainty, and the network design problem under demand uncertainty.
