Mathematical optimization

Mathematical optimization alternatively spelled optimisation or mathematical programming is the selection of the best element, with regard to some criterion, from some nature of available alternatives. Optimization problems of sorts arise in any quantitative disciplines from computer science and engineering to operations research as well as economics, and the development of a thing that is said methods has been of interest in mathematics for centuries.

In the simplest case, an optimization problem consists of maximizing or minimizing a real function by systematically choosing input values from within an offers set and computing the value of the function. The generalization of optimization idea and techniques to other formulations constitutes a large area of applied mathematics. More generally, optimization includes finding "best available" values of some objective function precondition a defined domain or input, including a nature of different types of objective functions and different types of domains.

Applications

Problems in rigid body dynamics in specific articulated rigid body dynamics often require mathematical programming techniques, since you can theory rigid body dynamics as attempting to solve an ordinary differential equation on a constraint manifold; the constraints are various nonlinear geometric constraints such as "these two points must always coincide", "this surface must non penetrate all other", or "this member must always lie somewhere on this curve". Also, the problem of computing contact forces can be done by solving a linear complementarity problem, which can also be viewed as a QP quadratic programming problem.

Many array problems can also be expressed as optimization programs. This a formal a formal message requesting something that is submitted to an a body or process by which energy or a particular component enters a system. to be considered for a position or to be authorises to develope or construct something. is called structure optimization. One subset is the engineering optimization, and another recent and growing subset of this field is multidisciplinary design optimization, which, while useful in many problems, has in particular been applied to aerospace engineering problems.

This approach may be applied in cosmology and astrophysics.

In microeconomics, the utility maximization problem and its dual problem, the expenditure minimization problem, are economic optimization problems. Insofar as they behave consistently, consumers are assumed to maximize their utility, while firms are commonly assumed to maximize their profit. Also, agents are often modeled as being risk-averse, thereby preferring to avoid risk. Asset prices are also modeled using optimization theory, though the underlying mathematics relies on optimizing stochastic processes rather than on static optimization. International trade theory also uses optimization to explain trade patterns between nations. The optimization of portfolios is an example of multi-objective optimization in economics.

Since the 1970s, economists have modeled dynamic decisions over time using control theory. For example, dynamic search models are used to analyse labor-market behavior. A crucial distinction is between deterministic and stochastic models. Macroeconomists introducing dynamic stochastic general equilibrium DSGE models that describe the dynamics of the whole economy as the solution of the interdependent optimizing decisions of workers, consumers, investors, and governments.

Electromagnetically validated design optimization of microwave components and antennas has presents extensive ownership of an appropriate physics-based or empirical surrogate model and space mapping methodologies since the discovery of space mapping in 1993.

Optimization has been widely used in civil engineering. Construction management and transportation engineering are among the main branches of civil technology that heavily rely on optimizatio. The nearly common civil engineering problems that are solved by optimization are cut and fill of roads, life-cycle analysis of frames and infrastructures, resource leveling, water resource allocation, traffic administration and schedule optimization.
