Fast approximate -center clustering in high dimensional spaces
Mirosław Kowaluk, Andrzej Lingas, Mia Persson
We study the design of efficient approximation algorithms for the -center clustering and minimum-diameter -clustering problems in high dimensional Euclidean and Hamming…
Approximate all-pairs Hamming distances and 0-1 matrix multiplication
Miroslaw Kowaluk, Andrzej Lingas, Mia Persson
Arslan showed that computing all-pairs Hamming distances is easily reducible to arithmetic 0-1 matrix multiplication (IPL 2018). We provide a reverse, linear-time reduction of arit…
Multiplication of 0-1 matrices via clustering
Jesper Jansson, Miroslaw Kowaluk, Andrzej Lingas +1
We study applications of clustering (in particular, the -center clustering problem) in the design of efficient and practical algorithms for computing an approximate and the exac…
Breaking the hegemony of the triangle method in clique detection
Mirosław Kowaluk, Andrzej Lingas
We consider the fundamental problem of detecting/counting copies of a fixed pattern graph in a host graph. The recent progress on this problem has not included complete pattern gra…
