Biobjective Online Bipartite Matchingces even though they have an edge available..As our main result, we introduce an algorithm which randomly discards some edges of the graph in a particular manner – thus enabling the necessary skipping of vertices – and simultaneously runs the color-oblivious algorithm .. We prove that this algorithm

Bounding the Potential Function in Congestion Games and Approximate Pure Nash Equilibria-increasing utility functions..We show that the value of the potential function Φ(.) of any outcome . of a congestion game approximates the optimum potential value Φ(..) by a factor . which only depends on the set of cost/utility functions ., and an additive term which is bounded by the sum of the t

Limiting Price Discrimination when Selling Products with Positive Network Externalities the item. The goal of the seller is to maximize his revenue. Previous work on this problem [7] studies the case where clients are offered the item in sequence and have to pay personalized prices. This is highly infeasible in large scale networks such as the Facebook graph: (1)?Offering items to the

Optimal Cost-Sharing in Weighted Congestion Gamesy (PoA). First, we prove that among all cost-sharing methods that guarantee the existence of pure Nash equilibria, the Shapley value minimizes the worst-case PoA. Second, if the guaranteed existence condition is dropped, then the proportional cost-sharing method minimizes the worst-case PoA over all
