Processing Operations with Restrictions in RDBMS without External Sorting: The Tetris Algorithm
Most operations of the relational algebra or SQL require a sorted stream of tuples for efficient processing. Therefore, processing complex relational queries relies on efficient a...

Load-Balanced Parallel Merge Sort on Distributed Memory Parallel Computers
Sort can be speeded up on parallel computers by dividing and computing data individually in parallel. Merge sort can be parallelized, however, the conventional algorithm implement...

Resource Oblivious Sorting on Multicores
We present a new deterministic sorting algorithm that interleaves the partitioning of a sample sort with merging. Sequentially, it sorts n elements in O(n log n) time cache-oblivi...

Counting All DCJ Sorting Scenarios
In genome rearrangements, the double cut and join (DCJ) operation, introduced by Yancopoulos et al., allows to represent most rearrangement events that could happen in multichromos...

On Sorting Permutations by Double-Cut-and-Joins
The problem of sorting permutations by double-cut-and-joins (SBD) arises when we perform the double-cut-and-join (DCJ) operations on pairs of unichromosomal genomes without the gen...
