Continuous Delivery Message Dissemination Problems under the Multicasting Communication Mode
We consider the Continuous Delivery Message Dissemination (CDMD) problem over the n-processor single-port complete (all links are present and are bidirectional) static network with...

Constant-approximation for target coverage problem in wireless sensor networks
—When a large amount of sensors are randomly deployed into a field, how can we make a sleep/activate schedule for sensors to maximize the lifetime of target coverage in the fie...

Lower Bounds on the Sample Complexity of Exploration in the Multi-armed Bandit Problem
We consider the Multi-armed bandit problem under the PAC (“probably approximately correct”) model. It was shown by Even-Dar et al. [5] that given n arms, it suffices to play th...

Covering Rectilinear Polygons with Axis-Parallel Rectangles
We give an O( log n) factor approximation algorithm for covering a rectilinear polygon with holes using axis-parallel rectangles. This is the first polynomial time approximation a...
