WebMay 3, 2013 · Sorted by: 4. One possible way to generate an interval graph with N nodes: create an array [1, 1, 2, 2, ... n, n] shuffle the array. create a graph: each node v_i corresponds to the pair of occurences of i in the shuffled array. two nodes v_i and v_j are connected with an edge iff i and j are interleaved in the array. In graph theory, an interval graph is an undirected graph formed from a set of intervals on the real line, with a vertex for each interval and an edge between vertices whose intervals intersect. It is the intersection graph of the intervals. Interval graphs are chordal graphs and perfect graphs. They can … See more An interval graph is an undirected graph G formed from a family of intervals $${\displaystyle S_{i},\quad i=0,1,2,\dots }$$ by creating one vertex vi for each interval Si, and connecting … See more Three vertices form an asteroidal triple (AT) in a graph if, for each two, there exists a path containing those two but no neighbor of the third. A graph is AT-free if it has no asteroidal … See more By the characterization of interval graphs as AT-free chordal graphs, interval graphs are strongly chordal graphs and hence perfect graphs. Their complements belong to the class of comparability graphs, and the comparability relations are precisely the See more If $${\displaystyle G}$$ is an arbitrary graph, an interval completion of $${\displaystyle G}$$ is an interval graph on the same vertex set that contains $${\displaystyle G}$$ as a subgraph. The parameterized version of interval completion (find an … See more Determining whether a given graph $${\displaystyle G=(V,E)}$$ is an interval graph can be done in $${\displaystyle O( V + E )}$$ time by seeking an ordering of the maximal cliques of $${\displaystyle G}$$ that is consecutive with respect to vertex inclusion. … See more The mathematical theory of interval graphs was developed with a view towards applications by researchers at the RAND Corporation's mathematics department, which included young researchers—such as Peter C.

Lecture 16 – Interval Order & Interval Graph Algorithms

WebJan 20, 2024 · Interval graphs are chordal graphs, so you can use a linear time algorithm for finding max clique in a chordal graph. This can be done by first finding a perfect elimination ordering, and then using the fact that every time a vertex is eliminated it forms a clique together with its neighbors that are not eliminated yet. WebAboutTranscript. Introducing intervals, which are bounded sets of numbers and are very useful when describing domain and range. We can use interval notation to show that a value falls between two endpoints. For example, -3≤x≤2, [-3,2], and {x∈ℝ -3≤x≤2} all mean that x is between -3 and 2 and could be either endpoint.
