Improved Parallel Algorithms for EF1 Allocations

Kishen N Gowda, D Ellis Hershkowitz, Richard Z Huang +1

Allocating indivisible goods among agents is a fundamental task in fair division. Recent work of Garg and Psomas [AAMAS 2025] initiated the study of parallel algorithms for…

Chamfer-Linkage for Hierarchical Agglomerative Clustering

Kishen N Gowda, Willem Fletcher, MohammadHossein Bateni +4

Hierarchical Agglomerative Clustering (HAC) is a widely-used clustering method based on repeatedly merging the closest pair of clusters, where inter-cluster distances are determine…

Faster Parallel Batch-Dynamic Algorithms for Low Out-Degree Orientation

Guy Blelloch, Andrew Brady, Laxman Dhulipala +3

A low out-degree orientation directs each edge of an undirected graph with the goal of minimizing the maximum out-degree of a vertex. In the parallel batch-dynamic setting, one can…

UFO Trees: Practical and Provably-Efficient Parallel Batch-Dynamic Trees

Quinten De Man, Atharva Sharma, Kishen N Gowda +1

The dynamic trees problem is to maintain a tree under edge updates while supporting queries like connectivity queries or path queries. Despite the first data structure for this fun…

Efficient Centroid-Linkage Clustering

MohammadHossein Bateni, Laxman Dhulipala, Willem Fletcher +4

We give an efficient algorithm for Centroid-Linkage Hierarchical Agglomerative Clustering (HAC), which computes a -approximate clustering in roughly time. We ob…

Optimal Parallel Algorithms for Dendrogram Computation and Single-Linkage Clustering

Laxman Dhulipala, Xiaojun Dong, Kishen N Gowda +1

Computing a Single-Linkage Dendrogram (SLD) is a key step in the classic single-linkage hierarchical clustering algorithm. Given an input edge-weighted tree , the SLD of is…

Improved Bi-point Rounding Algorithms and a Golden Barrier for -Median

Kishen N. Gowda, Thomas Pensyl, Aravind Srinivasan +1

The current best approximation algorithms for -median rely on first obtaining a structured fractional solution known as a bi-point solution, and then rounding it to an integer s…

Socially Fair Center-based and Linear Subspace Clustering

Sruthi Gorantla, Kishen N. Gowda, Amit Deshpande +1

Center-based clustering (e.g., -means, -medians) and clustering using linear subspaces are two most popular techniques to partition real-world data into smaller clusters. How…

A Parameterized Perspective on Attacking and Defending Elections

Kishen N. Gowda, Neeldhara Misra, Vraj Patel

We consider the problem of protecting and manipulating elections by recounting and changing ballots, respectively. Our setting involves a plurality-based election held across multi…
