81Transpose graph — In the mathematical and algorithmic study of graph theory, the converse[1], transpose[2] or reverse[3] of a directed graph G is another directed graph on the same set of vertices with all of the edges reversed compared to the orientation of the… …
82Neighbourhood (graph theory) — A graph consisting of 6 vertices and 7 edges For other meanings of neighbourhoods in mathematics, see Neighbourhood (mathematics). For non mathematical neighbourhoods, see Neighbourhood (disambiguation). In graph theory, an adjacent vertex of a… …
83Algorithmics of sudoku — The class of Sudoku puzzles consists of a partially completed row column grid of cells partitioned into N regions or zones each of size N cells, to be filled in using a prescribed set of N distinct symbols (typically the numbers {1, ..., N }), so …
84Guatemalan claim to Belizean territory — The Guatemalan claim to Belizean territory is an unresolved binational territorial dispute between the nations of Belize and Guatemala, neighbours in Central America. Belize, a former British colony with English as the official language, has been …
85Maximally stable extremal regions — Feature detection Output of a typical corner detection algorithm …
86Continuous-time quantum walk — A Continuous time quantum walk (CTQW) is a walk on a given connected graph that is dictated by a time varying unitary matrix that relies on the Hamiltonian of the quantum system and the adjacency matrix. CTQW belongs to what is known as Quantum… …
87Median graph — The median of three vertices in a median graph In mathematics, and more specifically graph theory, a median graph is an undirected graph in which any three vertices a, b, and c have a unique median: a vertex m(a,b,c) that belongs to shortest… …
88Task allocation and partitioning of social insects — Task allocation and partitioning refers to the way that tasks are chosen, assigned, subdivided, and coordinated (here, within a single colony of social insects). Closely associated are issues of communication that enable these actions to… …
89Matrix (mathematics) — Specific elements of a matrix are often denoted by a variable with two subscripts. For instance, a2,1 represents the element at the second row and first column of a matrix A. In mathematics, a matrix (plural matrices, or less commonly matrixes)… …
90Digraph (mathematics) — A directed graph or digraph G is an ordered pair G := (V, A) with * V is a set, whose elements are called vertices or nodes, * A is a set of ordered pairs of vertices, called directed edges, arcs, or arrows.It differs from an ordinary, undirected …
