Web10 apr. 2024 · F or 1 ≤ ℓ < k ≤ q, an ℓ-(q, k)-system is a k-u niform hypergraph (henceforth k-graph) whose edge set is the union of cliques with q vertices that pairwise share at most ℓ vertices. Such ...
Computing the transversal hypergraph has applications in combinatorial optimization, in game theory, and in several fields of computer science such as machine learning, indexing of databases, the satisfiability problem, data mining, and computer program optimization. Meer weergeven In graph theory, a vertex cover in a hypergraph is a set of vertices, such that every hyperedge of the hypergraph contains at least one vertex of that set. It is an extension of the notion of vertex cover in a graph Meer weergeven The hitting set problem is equivalent to the set cover problem: An instance of set cover can be viewed as an arbitrary bipartite graph, with sets represented by vertices on … Meer weergeven An example of a practical application involving the hitting set problem arises in efficient dynamic detection of race condition. … Meer weergeven A finite projective plane is a hypergraph in which every two hyperedges intersect. Every finite projective plane is r-uniform for some integer r. Denote by Hr the r-uniform projective … Meer weergeven Recall that a hypergraph H is a pair (V, E), where V is a set of vertices and E is a set of subsets of V called hyperedges. Each hyperedge may contain one or more vertices. Meer weergeven The computational problems minimum hitting set and hitting set are defined as in the case of graphs. If the maximum size of a hyperedge is restricted to d, then the problem of finding a minimum d-hitting set permits a d-approximation algorithm. … Meer weergeven A fractional vertex-cover is a function assigning a weight in [0,1] to each vertex in V, such that for every hyperedge e in E, the sum of fractions of vertices in e is at least 1. A vertex cover is a special case of a fractional vertex cover in which all weights are … Meer weergeven WebH0= (V 0;E) with degree vector m0, that covers p.

WebIn order to count the complexity of the texture in the image, a simple clustering method is used to cluster the image pixels. Pixels with high similarity are extracted as the same cluster, the boundaries between different clusters are extracted and the extracted boundaries are used for texture complexity analysis.
