To Store or Not to Store: a graph theoretical approach for Dataset Versioning

Anxin Guo, Jingwei Li, Pattara Sukprasert +3

In this work, we study the cost efficient data versioning problem, where the goal is to optimize the storage and reconstruction (retrieval) costs of data versions, given a graph of…

Practical Parallel Algorithms for Near-Optimal Densest Subgraphs on Massive Graphs

Pattara Sukprasert, Quanquan C. Liu, Laxman Dhulipala +1

The densest subgraph problem has received significant attention, both in theory and in practice, due to its applications in problems such as community detection, social network ana…

Constant Approximation for Individual Preference Stable Clustering

Anders Aamand, Justin Y. Chen, Allen Liu +4

Individual preference (IP) stability, introduced by Ahmadi et al. (ICML 2022), is a natural clustering objective inspired by stability and fairness constraints. A clustering is …

Simple Dynamic Spanners with Near-optimal Recourse against an Adaptive Adversary

Sayan Bhattacharya, Thatchaphol Saranurak, Pattara Sukprasert

Designing dynamic algorithms against an adaptive adversary whose performance match the ones assuming an oblivious adversary is a major research program in the field of dynamic grap…

Individual Preference Stability for Clustering

Saba Ahmadi, Pranjal Awasthi, Samir Khuller +4

In this paper, we propose a natural notion of individual preference (IP) stability for clustering, which asks that every data point, on average, is closer to the points in its own…

Approximating k-Edge-Connected Spanning Subgraphs via a Near-Linear Time LP Solver

Parinya Chalermsook, Chien-Chung Huang, Danupon Nanongkai +3

In the -edge-connected spanning subgraph (ECSS) problem, our goal is to compute a minimum-cost sub-network that is resilient against up to link failures: Given an -nod…

Retraction: Improved Approximation Schemes for Dominating Set Problems in Unit Disk Graphs

Jittat Fakcharoenphol, Pattara Sukprasert

Retraction note: After posting the manuscript on arXiv, we were informed by Erik Jan van Leeuwen that both results were known and they appeared in his thesis[vL09]. A PTAS for MDS…

Multi-transversals for Triangles and the Tuza's Conjecture

Parinya Chalermsook, Samir Khuller, Pattara Sukprasert +1

In this paper, we study a primal and dual relationship about triangles: For any graph , let be the maximum number of edge-disjoint triangles in , and be the min…

Finding All Useless Arcs in Directed Planar Graphs

Jittat Fakcharoenphol, Bundit Laekhanukit, Pattara Sukprasert

We present a linear-time algorithm for simplifying flow networks on directed planar graphs: Given a directed planar graph on vertices, a source vertex and a sink vertex …
