Taxonomy of Empirical Valence Bond methods

The use of Empirical Valence Bond methods to describe chemical reactions in complex environments (e.g. solvents and proteins) was pioneered by Warshel. I found the useful table below in a Comment by Jan Florian, arguing that some "new" methods with new acronyms are actually misnomers. [Aside: this is the same issue as The Best Paper Title and Abstract Ever].
