Abstract

Equivalence relations between programs are strongly connected to the formal definition of the semantics of programming languages. In addition they provide a basis for the formal justification of the development of programs by transformations. Besides equivalences there are various other relations on programs and computational structures, which help to get a better understanding of both programming languages and the programming activity. In particular, the study of relations between nondeterministic programs allows to compare different concepts of nondeterminism.
