2007 journal article

A very large scale neighborhood search algorithm for the q-mode problem

IIE TRANSACTIONS, 39(10), 971–984.

By: G. Kulkarni* & Y. Fathi n

author keywords: cluster analysis; data mining; local search/local improvement
TL;DR: A neighborhood search algorithm is proposed for solving the q-mode problem based on a very large scale neighborhood that is implicitly searched using network flow techniques and shows that in instances with strong natural clusters the algorithm consistently finds optimal or near-optimal solutions.

View selection for real conjunctive queries

ACTA INFORMATICA, 44(5), 289–321.

By: F. Afrati*, R. Chirkova n, M. Gergatsoulis* & V. Pavlaki*

TL;DR: This paper studies the complexity of the view-selection problem for conjunctive queries and views under set semantics, and shows that bag semantics is the “easiest to handle”, whereas under set and bag-set semantics the authors assume further restrictions on the query workload to achieve the same complexity.
