Reporting flock patterns on the GPU
(2013)
In this paper we study the problem of finding flock patterns in a set of trajectories of moving entities. A flock refers to a large enough subset of entities that move close to each other for a given time interval. We present ...

Solving common influence region queries with the GPU
(2013)
In this paper we propose and solve common influence region queries. We present GPU parallel algorithms, designed under CUDA architecture, for approximately solving the studied queries. We also provide and discuss experimental ...

Continuous surveillance of points by rotating floodlights
(2013)
Let P and F be sets of n ≥ 2 and m ≥ 2 points in the plane, respectively, so that P∪F is in general position. We study the problem of finding the minimum angle α ∈ [2π/m, 2π] such that one can install at each point of F a ...
