An Optimal Randomised Cell Probe Lower Bound for Approximate Nearest Neighbour Searching
We consider the approximate nearest neighbour search problem on the Hamming cube {0, 1}d. We show that a randomised cell probe algorithm that uses polynomial storage and word size...

Lower bounds for predecessor searching in the cell probe model
We consider a fundamental problem in data structures, static predecessor searching: Given a subset S of size n from the universe [m], store S so that queries of the form “What i...

Lower Bounds on the Loading of Degree-2 Multiple Bus Networks for Binary-Tree Algorithms
A binary-tree algorithm, Bin(n), proceeds level-bylevel from the leaves of a 2n -leaf balanced binary tree to its root. This paper deals with running binary-tree algorithms on mul...

Lower Bounds for Dynamic Algebraic Problems
Abstract. We consider dynamic evaluation of algebraic functions (matrix multiplication, determinant, convolution, Fourier transform, etc.) in the model of Reif and Tate; i.e., if f...

On lower bounds for MAC layer contention in CSMA/CA-based wireless networks
Wireless LANs operating within unlicensed frequency bands require random access schemes such as CSMA/CA, so that wireless networks from different administrative domains (for exam...
