In mathematics, a hypergraph is a generalization of a graph in which an edge can join any number of vertices. In contrast, in an ordinary graph, an edge connects exactly two vertices. Formally, a directed hypergraph is a pair $${\displaystyle (X,E)}$$, where $${\displaystyle X}$$ is a set of … Meer weergeven Undirected hypergraphs are useful in modelling such things as satisfiability problems, databases, machine learning, and Steiner tree problems. They have been extensively used in machine learning tasks as the … Meer weergeven Although hypergraphs are more difficult to draw on paper than graphs, several researchers have studied methods for the visualization … Meer weergeven Classic hypergraph coloring is assigning one of the colors from set $${\displaystyle \{1,2,3,...,\lambda \}}$$ to every vertex of a hypergraph in such a way that each hyperedge … Meer weergeven Let $${\displaystyle V=\{v_{1},v_{2},~\ldots ,~v_{n}\}}$$ and $${\displaystyle E=\{e_{1},e_{2},~\ldots ~e_{m}\}}$$. Every hypergraph has an $${\displaystyle n\times m}$$ Meer weergeven Many theorems and concepts involving graphs also hold for hypergraphs, in particular: • Matching in hypergraphs; • Vertex cover in hypergraphs (also … Meer weergeven Because hypergraph links can have any cardinality, there are several notions of the concept of a subgraph, called subhypergraphs, partial hypergraphs and section hypergraphs. Let $${\displaystyle H=(X,E)}$$ be the hypergraph … Meer weergeven A parallel for the adjacency matrix of a hypergraph can be drawn from the adjacency matrix of a graph. In the case of a graph, the adjacency matrix is a square matrix which indicates whether pairs of vertices are adjacent. Likewise, we can define the … Meer weergeven WebHypergraphs (with no uniformity restriction) are also the natural way to model clause sets of general SAT. Each hyperedge represents the single set of literals that is forbidden by some clause. These structures have also been studied in constraint satisfaction, under the name microstructure complements.
WebThe acyclic hypergraph partitioning problem is to partition the hypernodes of a directed acyclic hypergraph into a given number of blocks of roughly equal size such that the corresponding quotient graph is acyclic while minimizing an objective function on the partition. Here, we contribute the first n-level algorithm for the acyclic hypergraph … Web26 aug. 2014 · Definition of hypergraph, possibly with links to more information and implementations. hypergraph (data structure) Definition:A graphwhose hyperedgesconnect two or more vertices. Formal Definition:A hypergraph G can be defined as a pair (V, E), where V is a setof vertices, and E is a set of hyperedges between the vertices.
