JAG: Joint Attribute Graphs for Filtered Nearest Neighbor Search

Haike Xu, Guy Blelloch, Laxman Dhulipala +3

Despite filtered nearest neighbor search being a fundamental task in modern vector search systems, the performance of existing algorithms is highly sensitive to query selectivity a…

Deterministic Parallel High-Quality Hypergraph Partitioning

Robert Krause, Lars Gottesbüren, Nikolai Maas

We present a deterministic parallel multilevel algorithm for balanced hypergraph partitioning that matches the state of the art for non-deterministic algorithms. Deterministic para…

Parallel Unconstrained Local Search for Partitioning Irregular Graphs

Nikolai Maas, Lars Gottesbüren, Daniel Seemaier

We present new refinement heuristics for the balanced graph partitioning problem that break with an age-old rule. Traditionally, local search only permits moves that keep the block…

Linear-Time Multilevel Graph Partitioning via Edge Sparsification

Lars Gottesbüren, Nikolai Maas, Dominik Rosch +2

The current landscape of balanced graph partitioning is divided into high-quality but expensive multilevel algorithms and cheaper approaches with linear running time, such as singl…

Tera-Scale Multilevel Graph Partitioning

Daniel Salwasser, Daniel Seemaier, Lars Gottesbüren +1

We present TeraPart, a memory-efficient multilevel graph partitioning method that is designed to scale to extremely large graphs. In balanced graph partitioning, the goal is to div…
