Skyline queries: An introduction
2015
2015 6th International Conference on Information, Intelligence, Systems and Applications (IISA)
Several algorithms were proposed for skyline query processing, such as window-based, progressive, distributed, geometric-based, index-based, divideand-conquer, and dynamic programming algorithms. ...
As the number of objects that are returned in a skyline query may become large, there is also an extensive study for the cardinality of skyline queries. ...
The algorithm is I/O optimal and requires a logarithmic space in the worst case in the 2D space if there are not many overlaps in the R-tree.

An Efficient Index Method for the Optimal Route Query over Multi-Cost Networks
[article]
2020
arXiv
pre-print
We propose a novel partition-based index with contour skyline techniques to find the optimal route. We propose a vertex-filtering algorithm to facilitate the query processing. ...
However, there always are several kinds of cost in networks and users prefer to select an optimal route under the global consideration of these kinds of cost. ...
This index is a treestructured index constructed based on the concept of vertex cover and it is I/O-efficient when the input graph is too large to fit in main memory. ...

Lecture Notes in Computer Science
We present a novel distributed skyline query processing algorithm (DSL) that discovers skyline points progressively. ...
