Parameterized Algorithms for Upward Planarity

Steven Chaplick, Emilio Di Giacomo, Fabrizio Frati +3

We obtain new parameterized algorithms for the classical problem of determining whether a directed acyclic graph admits an upward planar drawing. Our results include a new fixed-pa…

Longest Cycle above Erdős-Gallai Bound

Fedor V. Fomin, Petr A. Golovach, Danil Sagunov +1

In 1959, Erdős and Gallai proved that every graph G with average vertex degree ad(G)\geq 2 contains a cycle of length at least ad(G). We provide an algorithm that for k\geq 0 in ti…

Detours in Directed Graphs

Fedor V. Fomin, Petr A. Golovach, William Lochet +3

We study two "above guarantee" versions of the classical Longest Path problem on undirected and directed graphs and obtain the following results. In the first variant of Longest Pa…

FPT Approximation for Fair Minimum-Load Clustering

Sayan Bandyapadhyay, Fedor V. Fomin, Petr A. Golovach +2

In this paper, we consider the Minimum-Load -Clustering/Facility Location (MLkC) problem where we are given a set of points in a metric space that we have to cluster and…

Lossy Kernelization of Same-Size Clustering

Sayan Bandyapadhyay, Fedor V. Fomin, Petr A. Golovach +2

In this work, we study the -median clustering problem with an additional equal-size constraint on the clusters, from the perspective of parameterized preprocessing. Our main res…

Parameterized Complexity of Feature Selection for Categorical Data Clustering

Sayan Bandyapadhyay, Fedor V. Fomin, Petr A. Golovach +1

We develop new algorithmic methods with provable guarantees for feature selection in regard to categorical data clustering. While feature selection is one of the most common approa…
