Randomized fault-detecting leader election in a bi-directional ring
Abstract. This article presents a randomized algorithm for leader election which uses bidirectionality of an asynchronous ring to force a node to "commit" to a coin flip ...

Improved combination of online algorithms for acceptance and rejection
Given two admission control algorithms that are cA-acceptcompetitive and cR-reject-competitive respectively, we give two ways to make an algorithm that is simultaneously O(cA)acce...
