Improved Exact and Heuristic Algorithms for Maximum Weight Clique

no code implementations1 Feb 2023 Roman Erhardt, Kathrin Hanauer, Nils Kriege, Christian Schulz, Darren Strash

We propose improved exact and heuristic algorithms for solving the maximum weight clique problem, a well-known problem in graph theory with many applications.

A general purpose algorithm for counting simple cycles and simple paths of any length

1 code implementation16 Dec 2016 Pierre-Louis Giscard, Nils Kriege, Richard C. Wilson

These comparisons show that the algorithm described here is the best general purpose algorithm for the class of graphs where $(\ell^{\omega-1}\Delta^{-1}+1) |S_\ell|\leq |\text{Cycle}_\ell|$, with $|\text{Cycle}_\ell|$ the total number of simple cycles of length at most $\ell$, including backtracks and self-loops.

Subgraph Matching Kernels for Attributed Graphs

no code implementations27 Jun 2012 Nils Kriege, Petra Mutzel

To compute the kernel we propose a graph-theoretical algorithm inspired by a classical relation between common subgraphs of two graphs and cliques in their product graph observed by Levi (1973).
