Maximum weight subgraph
WebA graph is P5-free when it does not contain a P5 (that is, a path with five vertices) as an induced subgraph. The class of P5-free graphs is of particular interest, especially with respect to the... WebNP-complete problems in graphs, such as enumeration and the selection of subgraphs with given characteristics, become especially relevant for large graphs and networks. Herein, particular statements with constraints are proposed to solve such problems, and subclasses of graphs are distinguished. We propose a class of prefractal graphs and review …

WebA system generates a topic graph based on the SERF data for high-ranking keywords in a search engine. Clustering may be based on (for example) degrees of intersection between links in search results of keywords from the SERF data, or keyword embeddings on the SERF data. The topic graph loosely clusters the keywords, such that the keywords have … WebMaximum Acyclic Subgraph and Feedback Arc Set Formally, the maximum acyclic subgraph (MAS) problem is dened as follows. We are given a directed graph G= (V,E) and a weight function w(e) that assigns a weight for each arc e∈E. The goal is to nd an acyclic graph G′= (V,E′) such that E′⊆Eand P e∈E′ w(e) is maximized.

WebWe answer the questions above by first bounding the expressive power of subgraph methods by 3-WL, and then proposing a general family of message-passing layers for subgraph methods that generalises all previous node-based Subgraph GNNs. Finally, we design a novel Subgraph GNN dubbed SUN, which theoretically unifies previous …
