Each technique has its own utility, scope, and limitations, as well as meeting resistance to use by experimentalists. The purpose of the book is to provide computational scientists, medicinal chemists and biologists with unique practical information and the underlying theories relating to modern Chemoinformatics and related drug discovery informatics technologies.
