Maxima

Definition

Maxima refer to the highest points in a set of values or a function, indicating the state of stability and equilibrium in thermodynamic systems. In the context of free energy calculations, maxima help identify favorable configurations or states that a system can occupy, thereby influencing reaction pathways and molecular dynamics. Understanding where these maxima occur is crucial for enhanced sampling techniques that aim to explore energy landscapes more efficiently.
