Improved Approximation for Vector Bin Packing
We study the d-dimensional vector bin packing problem, a well-studied generalization of bin packing arising in resource allocation and scheduling problems. Here we are given a set...

Simple and Fast Rounding Algorithms for Directed and Node-weighted Multiway Cut
We study the multiway cut problem in directed graphs and one of its special cases, the node-weighted multiway cut problem in undirected graphs. In DIRECTED MULTIWAY CUT (DIR-MC) t...

Constant Factor Approximation for Subset Feedback Set Problems via a new LP relaxation
We consider subset feedback edge and vertex set problems in undirected graphs. The input to these problems is an undirected graph G = (V, E) and a set S = {s1, s2, . . . , sk} ⊂...

Locality-sensitive Hashing without False Negatives
We consider a new construction of locality-sensitive hash functions for Hamming space that is covering in the sense that is it guaranteed to produce a collision for every pair of ...

New directions in nearest neighbor searching with applications to lattice sieving
To solve the approximate nearest neighbor search problem (NNS) on the sphere, we propose a method using locality-sensitive filters (LSF), with the property that nearby vectors ha...
