SATViz: Real-Time Visualization of Clausal Proofs

no code implementations13 Sep 2022 Tim Holzenkamp, Kevin Kuryshev, Thomas Oltmann, Lucas Wäldele, Johann Zuber, Tobias Heuer, Markus Iser

Visual layouts of graphs representing SAT instances can highlight the community structure of SAT instances.

Scalable Shared-Memory Hypergraph Partitioning

1 code implementation20 Oct 2020 Lars Gottesbüren, Tobias Heuer, Peter Sanders, Sebastian Schlag

With just four cores, Mt-KaHyPar is also slightly faster than the fastest sequential multilevel partitioner PaToH while producing better solutions on 83% of all instances.

Network Flow-Based Refinement for Multilevel Hypergraph Partitioning

2 code implementations SEA 2018 2018 Tobias Heuer, Peter Sanders, Sebastian Schlag

We present a refinement framework for multilevel hypergraph partitioning that uses max-flow computations on pairs of blocks to improve the solution quality of a $k$-way partition.

Engineering a direct k-way Hypergraph Partitioning Algorithm

no code implementations ALENEX 2017 2017 Yaroslav Akhremtsev, Tobias Heuer, Peter Sanders, Sebastian Schlag

We also remove several further bottlenecks in processing large hyperedges, develop a faster contraction algorithm, and a new adaptive stopping rule for local search.

Improving Coarsening Schemes for Hypergraph Partitioning by Exploiting Community Structure

1 code implementation SEA 2017 2017 Tobias Heuer, Sebastian Schlag

We present an improved coarsening process for multilevel hypergraph partitioning that incorporates global information about the community structure.
