We present a distributed 2-approximation algorithm for the minimum vertex cover problem. The algorithm is deterministic, and it runs in (∆ + 1)2 synchronous communication rounds,...
This paper presents elastic transactions, a variant of the transactional model. Upon conflict detection, an elastic transaction might drop what it did so far within a separate tra...
A contention-sensitive data structure is a concurrent data structure in which the overhead introduced by locking is eliminated in the common cases, when there is no contention, or ...
Abstract. Optimistic and nonblocking concurrent algorithms are increasingly finding their way into practical use; an important example is software transactional memory implementat...
Given an undirected graph and 0 ≤ ≤ 1, a set of nodes is called -near clique if all but an fraction of the pairs of nodes in the set have a link between them. In this paper we...
