A Framework for Approximation Schemes on Disk Graphs
Daniel Lokshtanov, Fahad Panolan, Saket Saurabh +2
We initiate a systematic study of approximation schemes for fundamental optimization problems on disk graphs, a common generalization of both planar graphs and unit-disk graphs. Ou…

Boolean and -Matrix Factorization: From Theory to Practice
Fedor Fomin, Fahad Panolan, Anurag Patil +1
Boolean Matrix Factorization (BMF) aims to find an approximation of a given binary matrix as the Boolean product of two low-rank binary matrices. Binary data is ubiquitous in many…

Partial Vertex Cover on Graphs of Bounded Degeneracy
Fahad Panolan, Hannane Yaghoubizade
In the Partial Vertex Cover (PVC) problem, we are given an -vertex graph and a positive integer , and the objective is to find a vertex subset of size maximizing…
