A 3/2-Approximation Algorithm for the Graph Balancing Problem with Two Weights
In the pursuit of finding subclasses of the makespan minimization problem on unrelated parallel machines that have approximation algorithms with approximation ratio better than 2, the graph balancing problem has been of current interest.

Approximation Algorithms for $\ell_0$-Low Rank Approximation
We study the $\ell_0$-Low Rank Approximation Problem, where the goal is, given an $m \times n$ matrix $A$, to output a rank-$k$ matrix $A'$ for which $\|A'-A\|_0$ is minimized. Here, for a matrix $B$, $\|B\|_0$ denotes the number of its non-zero entries.

Approximate Discrete Reconstruction Algorithm [PDF]
Discrete tomography deals with tomographic reconstruction of greyscale images for which the set of possible grey levels is discrete and small. Here, we develop a discrete approximate reconstruction algorithm. Our algorithm computes an image that has only grey values belonging to a given finite set.

Clustering Affine Subspaces: Algorithms and Hardness [PDF]
We study a generalization of the famous k-center problem where each object is an affine subspace of dimension Δ, and give either the first or significantly improved algorithms and hardness results for many combinations of parameters.

Algorithms and error bounds for multivariate piecewise constant approximation
We review the surprisingly rich theory of approximation of functions of many vari- ables by piecewise constants. This covers for example the Sobolev-Poincar´e inequalities, parts of the theory of nonlinear approximation, Haar wavelets and tree ...

Counting With Tinytable: Every Bit Counts!
Bloom filters are space efficient data structures that support approximate membership queries. They are easily extensible but incur significant overheads when extended to support additional functionality, such as removals or counting.

Minimizing Travel Time and Latency in Multi-Capacity Ride-Sharing Problems
Motivated by applications in ride-sharing and truck-delivery, we study the problem of matching a number of requests and assigning them to cars. A number of cars are given, each of which consists of a location and a speed, and a number of requests are ...
