Large Supports are Required for Well-Supported Nash Equilibria
We prove that for any constant k and any < 1, there exist bimatrix win-lose games for which every -WSNE requires supports of cardinality greater than k. To do this, we provide ...

Approximating Upper Degree-Constrained Partial Orientations
In the Upper Degree-Constrained Partial Orientation (UDPO) problem we are given an undirected graph G = (V, E), together with two degree constraint functions d− , d+ : V → N. ...

On Guillotine Cutting Sequences
Imagine a wooden plate with a set of non-overlapping geometric objects painted on it. How many of them can a carpenter cut out using a panel saw making guillotine cuts, i.e., only...

Sequential Importance Sampling Algorithms for Estimating the All-Terminal Reliability Polynomial of Sparse Graphs
The all-terminal reliability polynomial of a graph counts its connected subgraphs of various sizes. Algorithms based on sequential importance sampling (SIS) have been proposed to ...

On Approximating Node-Disjoint Paths in Grids
In the Node-Disjoint Paths (NDP) problem, the input is an undirected n-vertex graph G, and a collection {(s1, t1), . . . , (sk, tk)} of pairs of vertices called demand pairs. The ...

Zero-One Laws for Sliding Windows and Universal Sketches
Given a stream of data, a typical approach in streaming algorithms is to design a sophisticated algorithm with small memory that computes a specific statistic over the streaming ...

Tight Bounds for Graph Problems in Insertion Streams
Despite the large amount of work on solving graph problems in the data stream model, there do not exist tight space bounds for almost any of them, even in a stream with only edge ...
