We study the power assignment problem in radio networks, where each radio station can transmit in one of two possible power levels, corresponding to two ranges – short and long....
Given a set of rectangles we are asked to pack as many of them as possible into a bigger rectangle. The rectangles packed may not overlap and may not be rotated. This problem is NP...
For n disjoint line segments in the plane we can construct a binary encompassing tree such that every vertex is pointed, what’s more, at every segment endpoint all incident edges...

We present improved cache-oblivious data structures and algorithms for breadth-first search and the single-source shortest path problem on undirected graphs with non-negative edge...
Sampling has been successfully used to identify performance optimization opportunities. We would like to apply similar techniques to check program correctness. Unfortunately, samp...
