Model predictive control MPC is a group of algorithms that help manage production in chemical plants by dictating production in each batch.

While often formulated as linear programs because the resulting models are more stable, robust and easier to solve, MPC models are sometimes made with quadratic programming. Least squares regression is one of the most common types of regression, and works by minimizing the sum of the squares of the difference between data points and a proposed fit.

Quadratic optimization is one method that can be used to perform a least squares regression and is more flexible than most linear methods. One formulation for a quadratic programming regression model is as follows: 3. In this model, and are the unknown regression parameters, is an identity matrix, and and contain data about the independent and dependent variables respectively. Quadratic programming is used in a wide range of applications not touched upon in the sample presented above.

Other major areas in which QP's are relied upon include signal and image processing 12 and a subfield of optimization called partial differential constrained optimization. Additionally, Sequential quadratic programming , an algorithm for solving more complicated NLP's that uses QP subproblems, is one of the most important applications. Quadratic programming, the problem of optimizing a quadratic function, have been widely used since its development in the s because it is a simple type of non-linear programming that can accurately model many real world systems, notably ones dependent on two variables.

Problems formulated this way are straightforward to optimize when the objective function is convex. QP has applications in finance, various types of computer systems, statistics, chemical production, and in algorithms to solve more complex NLP's.
