Quadratic programming

Definition

Quadratic programming is a type of mathematical optimization problem where the objective function is quadratic, meaning it involves terms that are squared, and the constraints are linear. This method is particularly useful in scenarios where one seeks to minimize or maximize a quadratic function while adhering to certain linear constraints. In energy storage deployment, quadratic programming can effectively optimize the allocation of resources and manage trade-offs between different operational parameters.
