On the Approximability of Budgeted Allocations and Improved Lower Bounds for Submodular Welfare Maximization and GAP
In this paper we consider the following maximum budgeted allocation (MBA) problem: Given a set of m indivisible items and n agents; each agent i willing to pay bij on item j and w...

Lower bounds for approximate polygon decomposition and minimum gap
We consider the problem of decomposing polygons (with holes) into various types of simpler polygons. We focus on the problem of partitioning a rectilinear polygon, with holes, int...

Exact Distribution of Deletion Sizes for Unavoidable Strings
We constructively prove the exact distribution of deletion sizes for unavoidable strings, under the reductive decidability method of Zimin and Bean et al. Bounds such as these on ...

Lower Bounds for Multicast Message Authentication
Message integrity from one sender to one receiver is typically achieved by having the two parties share a secret key to compute a Message Authentication Code (MAC). We consider the...
