Non-linear anonymous pricing combinatorial auctions

Drexl, Andreas; Jörnsten, Kurt O.; Knof, Diether - 2007

In combinatorial auctions the pricing problem is of main concern since it is the means by which the auctioneer signals the result of the auction to the participants. In order for the auction to be regarded as fair among the various participants the price signals should be such that a participant...

Network Formulations of Mixed-Integer Programs

Conforti, Michele - 2007

We consider mixed-integer sets of the type MIX TU = {x : Ax amp;#8805; b; xi integer, i amp;#8712; I}, where A is a totally unimodular matrix, b is an arbitrary vector and I is a nonempty subset of the column indices of A. We show that the problem of checking nonemptiness of a set MIX TU is NP-complete...

Integer programming models for round robin tournaments

Briskorn, Dirk; Drexl, Andreas - 2006

Generally speaking in sports competition a number of teams play against each other over a period of time according to a certain scheme. The round robin scheme is very popular in many team sports like soccer and basketball. In this paper we study several basic variants of round robin tournaments....
