Balanced separator
More precisely, there is always exactly one or exactly two vertices, which amount to such a separator, depending on whether the tree is centered or bicentered. As opposed to these examples, not all vertex separators are balanced, but that property is most useful for applications in computer science, such as the … 더 보기 In graph theory, a vertex subset $${\displaystyle S\subset V}$$ is a vertex separator (or vertex cut, separating set) for nonadjacent vertices a and b if the removal of S from the graph separates a and b into distinct 더 보기 Consider a grid graph with r rows and c columns; the total number n of vertices is r × c. For instance, in the illustration, r = 5, c = 8, and n = 40. If r is … 더 보기 • Chordal graph, a graph in which every minimal separator is a clique. • k-vertex-connected graph 더 보기 Let S be an (a,b)-separator, that is, a vertex subset that separates two nonadjacent vertices a and b. Then S is a minimal (a,b)-separator if no proper subset of S separates a and b. More generally, S is called a minimal separator if it is a minimal separator for … 더 보기 1. ^ George (1973). Instead of using a row or column of a grid graph, George partitions the graph into four pieces by using the union of a row and a column as a separator. 2. ^ Jordan (1869) 3. ^ Golumbic (1980). 더 보기 웹2024년 8월 11일 · Minimum Balanced Separators problem is to nd a set X⊆V such that Xis an -balanced separator and SXS is minimum. 1. Observe that Minimum Balanced Separators is NP-hard. By setting w≡1 and = 1 SVS we basically search for a minimum vertex cover, which is one of the classical NP-hard problems.
