• Branch and bound — (BB) is a general algorithm for finding optimal solutions of various optimization problems, especially in discrete and combinatorial optimization. It consists of a systematic enumeration of all candidate solutions, where large subsets of… …   Wikipedia

• Viscosity solution — In mathematics, the viscosity solution concept was introduced in the early 1980s by Pierre Louis Lions and Michael Crandall as a generalization of the classical concept of what is meant by a solution to a partial differential equation (PDE). It… …   Wikipedia

• Meshfree methods — are a particular class of numerical simulation algorithms for the simulation of physical phenomena. Traditional simulation algorithms relied on a grid or a mesh, meshfree methods in contrast use the geometry of the simulated object directly for… …   Wikipedia

• Orders of magnitude (numbers) — The logarithmic scale can compactly represent the relationship among variously sized numbers. This list contains selected positive numbers in increasing order, including counts of things, dimensionless quantity and probabilities. Each number is… …   Wikipedia

• Rayleigh-Ritz method — In applied mathematics and mechanical engineering, the Rayleigh Ritz method is a widely used, classical method for the calculation of the natural vibration frequency of a structure in the second or higher order. It is a direct variational method… …   Wikipedia

• Limit superior and limit inferior — In mathematics, the limit inferior (also called infimum limit, liminf, inferior limit, lower limit, or inner limit) and limit superior (also called supremum limit, limsup, superior limit, upper limit, or outer limit) of a sequence can be thought… …   Wikipedia

• Dual problem — In constrained optimization, it is often possible to convert the primal problem (i.e. the original form of the optimization problem) to a dual form, which is termed a dual problem. Usually dual problem refers to the Lagrangian dual problem but… …   Wikipedia
