On the Cost of Recomputing: Tight Bounds on Pebbling with Faults
We introduce a formal framework to study the time and space complexity of computing with faulty memory. For the fault-free case, time and space complexities were studied using the...

On the complexity of distributed graph coloring
Coloring the nodes of a graph with a small number of colors is one of the most fundamental problems in theoretical computer science. In this paper, we study graph coloring in a di...

New Bounds for the Controller Problem
The (M, W)-controller, originally studied by Afek, Awerbuch, Plotkin, and Saks, is a basic ted tool that provides an abstraction for managing the consumption of a global resource ...

Joint optimization of segmentation and appearance models
Many interactive image segmentation approaches use an objective function which includes appearance models as an unknown variable. Since the resulting optimization problem is NP-har...

Fast Globally Optimal 2D Human Detection with Loopy Graph Models
This paper presents an algorithm for recovering the globally optimal 2D human figure detection using a loopy graph model. This is computationally challenging because the time comp...
