More Haste, Less Waste: Lowering the Redundancy in Fully Indexable Dictionaries
Abstract. We consider the problem of representing, in a compressed format, a bitvector S of m bits with n 1s, supporting the following operations, where b ∈ {0, 1}:

Delays induce an exponential memory gap for rendezvous in trees
The aim of rendezvous in a graph is meeting of two mobile agents at some node of an unknown anonymous connected graph. The two identical agents start from arbitrary nodes in the g...

Oblivious Transfer Is Symmetric
We show that oblivious transfer of bits from A to B can be obtained from a single instance of the same primitive from B to A. Our reduction is perfect and shows that oblivious tran...

On Compressibility of Protein Sequences
We consider the problem of compressibility of protein sequences. Based on an observed genome-scale long-range correlation in concatenated protein sequences from different organism...

Distributed Agreement with Optimal Communication Complexity
We consider the problem of fault-tolerant agreement in a crash-prone synchronous system. We present a new randomized consensus algorithm that achieves optimal communication effici...
