51Propositional directed acyclic graph — A propositional directed acyclic graph (PDAG) is a data structure that is used to represent a Boolean function. A Boolean function can be represented as a rooted, directed acyclic graph of the following form: * Leaves are labeled with op (true),… …
52Median 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… …
53Differentiable function — A differentiable function The absolute value function is not …
54Concave function — In mathematics, a concave function is the negative of a convex function. A concave function is also synonymously called concave downwards, concave down, convex upwards, convex cap or upper convex. Contents 1 Definition 2 Properties 3 Examples …
55Power graph analysis — In computational biology, power graph analysis is a method for the analysis andrepresentation of complex networks. Power graph analysis is the computation, analysis and visual representation of a power graph from a graphs (networks).Power graph… …
56Intersection number (graph theory) — In the mathematical field of graph theory, the intersection number of a graph is the smallest number of elements in a representation of G as an intersection graph of finite sets. Equivalently, it is the smallest number of cliques needed to cover… …
57Gain graph — A gain graph is a graph whose edges are labelled invertibly, or orientably, by elements of a group G . This means that, if an edge e in one direction has label g (a group element), then in the other direction it has label g −1. The label function …
58Linear function — In mathematics, the term linear function can refer to either of two different but related concepts.Analytic geometryIn analytic geometry, the term linear function is sometimes used to mean a first degree polynomial function of one variable. These …
59Error function — Plot of the error function In mathematics, the error function (also called the Gauss error function) is a special function (non elementary) of sigmoid shape which occurs in probability, statistics and partial differential equations. It is defined …
60Ihara zeta function — In mathematics, the Ihara zeta function closely resembles the Selberg zeta function, and is used to relate the spectrum of the adjacency matrix of a graph G = (V, E) to its Euler characteristic. The Ihara zeta function was first defined by… …
