Optimization

Definition

Optimization is the process of making something as effective, perfect, or functional as possible. In scientific contexts, it often involves adjusting variables in a model or system to minimize or maximize a particular objective, such as energy, time, or cost. By optimizing a system, researchers can find the most stable configurations, which is essential in understanding molecular interactions and behaviors.
