Optimization

Definition

Optimization is the mathematical process of finding the maximum or minimum value of a function, often subject to certain constraints. This concept is crucial in various fields, including economics and engineering, as it helps determine the most efficient solutions for problems involving limited resources or conditions. Understanding optimization can lead to better decision-making by maximizing outputs or minimizing costs in real-world scenarios.
