Nonlinear programming

Definition

Nonlinear programming is a mathematical optimization technique where the objective function or constraints are nonlinear, meaning they do not form straight lines when graphed. This approach is essential in various fields for solving complex problems that involve multiple variables and constraints, often used in optimizing energy storage deployment where factors like cost, capacity, and efficiency interact in non-linear ways.
