The discrete Kuhn-Tucker theorem and its application to auctions

Author

  • Yokote, Koji

Abstract

Using a notion of convexity in discrete convex analysis, we introduce a discrete analogue of the Kuhn-Tucker theorem. We apply it to an auction model and show that existing iterative auctions can be viewed as the process of finding a saddle point of the Lagrange function.
