Optimal Average Case Sorting on Arrays
Abstract. We present algorithms for sorting and routing on two-dimensional mesh-connected parallel architectures that are optimal on average. If one processor has many packets then...

Time Optimal Algorithms for Black Hole Search in Rings
In a network environments supporting mobile entities (called robots or agents), a black hole is harmful site that destroys any incoming entity without leaving any visible trace. Th...

On the average case performance of some greedy approximation algorithms for the uncapacitated facility location problem
In combinatorial optimization, a popular approach to NP-hard problems is the design of approximation algorithms. These algorithms typically run in polynomial time and are guarante...

An Improved Algorithm for Subdivision Traversal without Extra Storage
We describe an algorithm for enumerating all vertices, edges and faces of a planar subdivision stored in any of the usual pointer-based representations, while using only a constant...
