This paper discusses how to efficiently choose from n unknown distributions the k ones whose means are the greatest by a certain metric, up to a small relative error. We study the topic under two standard settings—multi-armed bandits and hidden bipartite graphs—which differ in the nature of the input distributions. In the former setting, each distribution(More)
The suffix array is a fundamental data structure for many applications that involve string searching and data compression. Designing time/space-efficient suffix array construction algorithms has attracted significant attentions and considerable advances have been made in the last 20 years. We obtain the suffix array construction algorithms that are optimal(More)
