From the reviews:
"The book distinguishes itself as a concise, formal introduction to the field of constraint programming. In general, concision and precision come in pairs in this book, and the authors should be congratulated for this. ... the uniform style of this book makes it easier and easier to be read. Its structure is also well designed and concocts to create a fluid presentation ... . Anybody looking for a formal, essential but never shallow introduction to the field should definitely consider this book." (Rosella Gennari, Journal of Logic, Language and Information, Vol. 14, 2005)
