The Networked Common Goods Game
Abstract. We introduce a new class of games called the networked common goods game (NCGG), which generalizes the well-known common goods game [12]. We focus on a fairly general sub...

On the approximability of two tree drawing conventions
We consider two aesthetic criteria for the visualization of rooted trees: inclusion and tip-over. Finding the minimum area layout according to either of these two standards is an ...

Hybrid rounding techniques for knapsack problems
We address the classical knapsack problem and a variant in which an upper bound is imposed on the number of items that can be selected. We show that appropriate combinations of ro...

Interval Subset Sum and Uniform-Price Auction Clearing
Abstract. We study the interval subset sum problem (ISSP), a generalization of the classic subset-sum problem, where given a set of intervals, the goal is to choose a set of intege...
