Processing Top-k Join Queries
We consider the problem of efficiently finding the top-k answers for join queries over web-accessible databases. Classical algorithms for finding top-k answers use branch-and-b...

Cache-Oblivious Dynamic Dictionaries with Update/Query Tradeoffs
Several existing cache-oblivious dynamic dictionaries achieve O(logB N) (or slightly better O(logB N M )) memory transfers per operation, where N is the number of items stored, M ...
