A surprising thing about this book is that it appears to be the first to use fuzzy logic in chemistry. Given that it was published in 1997, that seems rather late, since fuzzy logic was well established in computing and electric engineering in the 1980s.
Ah, but better late than never. Since most chemists have never dealt with fuzzy logic, the editor chose the wise step of having several research chemists write the chapters. Hopefully, this will ease acceptance of the method amongst chemists.
The subjects of the chapters tend to be hard, unsurprisingly. No softball simple textbook examples. Instead, we deal with issues like determining the shape of a large molecule, or the design of a drug.
