121Tree (graph theory) — Trees A labeled tree with 6 vertices and 5 edges Vertices v Edges v 1 Chromatic number …
122Kruskal's algorithm — is an algorithm in graph theory that finds a minimum spanning tree for a connected weighted graph. This means it finds a subset of the edges that forms a tree that includes every vertex, where the total weight of all the edges in the tree is… …
123Clique problem — The brute force algorithm finds a 4 clique in this 7 vertex graph (the complement of the 7 vertex path graph) by systematically checking all C(7,4)=35 4 vertex subgraphs for completeness. In computer science, the clique problem refers to any of… …
124Euclidean minimum spanning tree — The Euclidean minimum spanning tree or EMST is a minimum spanning tree of a set of points in the plane (or more generally in Bbb{R}^n), where the weight of the edge between each pair of points is the distance between those two points. In simpler… …
125Cycle index — In mathematics, and in particular in the field of combinatorics, cycle indices are used in combinatorial enumeration when symmetries are to be taken into account. This is particularly important in species theory. Each permutation π of a finite… …
126Reverse-delete algorithm — The reverse delete algorithm is an algorithm in graph theory used to obtain a minimum spanning tree from a given connected, edge weighed graph. If the graph is disconnected, this algorithm will find a minimum spanning tree for each disconnected… …
127graph theory — Math. the branch of mathematics dealing with linear graphs. [1965 70] * * * Mathematical theory of networks. A graph consists of nodes (also called points or vertices) and edges (lines) connecting certain pairs of nodes. An edge that connects a… …
128Cycle double cover — Unsolved problems in mathematics Does every bridgeless graph have a multiset of cycles covering every edge exactly twice? …
