Adjacency matrix — In mathematics and computer science, an adjacency matrix is a means of representing which vertices (or nodes) of a graph are adjacent to which other vertices. Another matrix representation for a graph is the incidence matrix. Specifically, the… … Wikipedia
Incidence matrix — In mathematics, an incidence matrix is a matrix that shows the relationship between two classes of objects. If the first class is X and the second is Y, the matrix has one row for each element of X and one column for each element of Y. The entry… … Wikipedia
Logical matrix — A logical matrix, binary matrix, relation matrix, Boolean matrix, or (0,1) matrix is a matrix with entries from the Boolean domain B = {0, 1}. Such a matrix can be used to represent a binary relation between a pair of finite sets. Contents 1… … Wikipedia
Binary matrix — In mathematics, particularly matrix theory, a binary matrix or (0,1) matrix is a matrix in which each entry is either zero or one. For example::egin{pmatrix}0 11 0end{pmatrix} is a 2 × 2 binary matrix.Frequently operations on binary matrices are … Wikipedia
Permanent is sharp-P-complete — The correct title of this article is Permanent is #P complete. The substitution or omission of the # sign is because of technical restrictions. In a 1979 paper Leslie Valiant proved[1] that the problem of computing the permanent of a matrix is #P … Wikipedia
Computing the permanent — In mathematics, the computation of the permanent of a matrix is a problem that is believed to be more complex than the computation of the determinant of a matrix despite the apparent similarity of the definitions. The permanent is defined… … Wikipedia
