Optimization

Definition

Optimization is the process of making something as effective or functional as possible, often by adjusting parameters or conditions to achieve the best outcome. In robotics, this involves refining algorithms and control strategies to maximize performance, minimize errors, or efficiently utilize resources. It connects closely to machine learning techniques and algorithm design, where finding the best solution to a problem is essential for achieving desired behaviors and actions in robotic systems.
