Zakaria Ye,Rachid Elazouzi,Tania Jiménezll set about the formal derivation of programs from specifications. In some sense, therefore, these chapters are competing. We make no pretence that the competition is fair. For the reader who skips through this chapter, some common elements are repeated in Chapter 3

Proofs are difficult, though even with the use of powerful theorem provers. This volume explains and illustrates an alternative method, which allows the construction of (necessarily cor
