51Approximation error — The approximation error in some data is the discrepancy between an exact value and some approximation to it. An approximation error can occur because the measurement of the data is not precise due to the instruments. (e.g., the accurate reading… …
52WKB approximation — In physics, the WKB (Wentzel–Kramers–Brillouin) approximation, also known as WKBJ (Wentzel–Kramers–Brillouin–Jeffreys) approximation, is the most familiar example of a semiclassical calculation in quantum mechanics in which the wavefunction is… …
53Cocoloring — with 3 colors (upper left figure): a proper 3 coloring of this graph is impossible. The blue subgraph forms a clique (bottom right figure), while the red and green subgraphs form cliques on the graph s complement. In graph theory, a cocoloring of …
54Set cover problem — The set covering problem is a classical question in computer science and complexity theory. As input you are given several sets. They may have some elements in common. You must select a minimum number of these sets so that the sets you have… …
55Optimization problem — In mathematics and computer science, an optimization problem is the problem of finding the best solution from all feasible solutions. Optimization problems can be divided into two categories depending on whether the variables are continuous or… …
56Mollifier — A mollifier (top) in dimension one. At the bottom, in red is a function with a corner (left) and sharp jump (right), and in blue is its mollified version. In mathematics, mollifiers (also known as approximations to the identity) are smooth… …
57Reflection mapping — An example of reflection mapping. In computer graphics, environment mapping, or reflection mapping, is an efficient Image based lighting technique for approximating the appearance of a reflective surface by means of a precomputed texture image.… …
58Binomial probability — typically deals with the probability of several successive decisions, each of which has two possible outcomes. Definition The probability of an event can be expressed as a binomial probability if its outcomes can be broken down into two… …
59Radial basis function — A radial basis function (RBF) is a real valued function whose value depends only on the distance from the origin, so that phi(mathbf{x}) = phi(||mathbf{x}||); or alternatively on the distance from some other point c , called a center , so that… …
60Connected dominating set — In graph theory, a connected dominated set and a maximum leaf spanning tree are two closely related structures defined on an undirected graph. Contents 1 Definitions 2 Complementarity 3 Algorithms 4 Applic …
