Energy Minimization

Definition

Energy minimization refers to the process of finding the lowest energy state or configuration of a system, which is often critical in optimization problems and homogenization. This concept is rooted in the idea that systems tend to evolve towards states that minimize energy, leading to stable configurations. Understanding energy minimization is essential for solving various mathematical and physical problems where optimality and stability are required.
