Broadly speaking, docking is a search or optimization problem, which necessitates a way of ranking potential dockings. The complexity of biological molecules adds an additional wrinkle: fewer levels of conformational flexibility can be modeled to simplify unmanageable searches. The next two sections briefly discuss the types of scoring functions and the level of molecular flexibility that is modeled. 1 Scoring Functions The extent of interaction between two molecules is usually expressed quantitatively by an energy value, which is ultimately based on a model of the physical chemistry of atomic interactions.
