Share the Multicast Payment Fairly
Multicast routing uses a structure, either a tree or a mesh, to connect the receivers to the source, thus saving the bandwidth. How to share the cost among the receivers in a certa...

RIATA-HGT: A Fast and Accurate Heuristic for Reconstructing Horizontal Gene Transfer
Horizontal gene transfer (HGT) plays a major role in microbial genome diversification, and is claimed to be rampant among various groups of genes in bacteria. Further, HGT is a ma...

Algorithms for Terminal Steiner Trees
The terminal Steiner tree problem (TST) consists of finding a minimum cost Steiner tree where each terminal is a leaf. We describe a factor 2ρ−ρ/(3ρ−2) approximation algor...

Opportunistic Data Structures for Range Queries
Abstract In this paper, we study the problem of supporting range sum queries on a compressed sequence of values. For a sequence of n k-bit integers, k ≤ O(log n), our data struct...

Randomized Quicksort and the Entropy of the Random Source
Abstract. The worst-case complexity of an implementation of Quicksort depends on the random number generator that is used to select the pivot elements. In this paper we estimate th...
