Weighted Equitability and Matroid-Constrained Discrepancy

Kristóf Bérczi, Siyue Liu, Victor Reis +1

We prove weighted matroid equitability. Let be a matroid whose ground set can be partitioned into bases, and assign a nonnegative weight to every element. T…

Matroid Secretary via Labeling Schemes

Kristóf Bérczi, Vasilis Livanos, José Soto +1

The Matroid Secretary Problem (MSP) is one of the most prominent settings for online resource allocation and optimal stopping. A decision-maker is presented with a ground set of el…

Finding Spanning Trees with Perfect Matchings

Kristóf Bérczi, Tamás Király, Yusuke Kobayashi +2

We investigate the tractability of a simple fusion of two fundamental structures on graphs, a spanning tree and a perfect matching. Specifically, we consider the following problem:…

Multiway Cuts with a Choice of Representatives

Kristóf Bérczi, Tamás Király, Daniel P. Szabo

In this paper, we study several generalizations of multiway cut where the terminals can be chosen as \emph{representatives} from sets of \emph{candidates} . In this…

Matroid Intersection under Minimum Rank Oracle

Mihály Bárász, Kristóf Bérczi, Tamás Király +3

In this paper, we consider the tractability of the matroid intersection problem under the minimum rank oracle. In this model, we are given an oracle that takes as its input a set o…

Hypergraph Connectivity Augmentation in Strongly Polynomial Time

Kristóf Bérczi, Karthekeyan Chandrasekaran, Tamás Király +1

We consider hypergraph network design problems where the goal is to construct a hypergraph that satisfies certain connectivity requirements. For graph network design problems where…

Approximating maximum-size properly colored forests

Yuhang Bai, Kristóf Bérczi, Gergely Csáji +1

In the Properly Colored Spanning Tree problem, we are given an edge-colored undirected graph and the goal is to find a properly colored spanning tree, i.e., a spanning tree in whic…

Splitting-off in Hypergraphs

Kristóf Bérczi, Karthekeyan Chandrasekaran, Tamás Király +1

The splitting-off operation in undirected graphs is a fundamental reduction operation that detaches all edges incident to a given vertex and adds new edges between the neighbors of…
