A k-ary n-tuple necklace is an equivalence class of k-ary strings under rotation. The classical idea is to treat them as characters. As the numbers being treated as characters can always being treated as numbers, like we treat char and int as the same type of variables in computer science, we present a new arithmetic algorithm using the decomposition of the ring Z/(kn – 1) on generating necklaces...
In this paper, we study the important performance issues in using the purging-range query to reclaim old data versions to be free blocks in a flash-based multi-version database. To reduce the overheads for using the purging-range query in garbage collection, the physical block labeling (PBL) scheme is proposed to provide a better estimation on the purging version number to be used for purging old...
