  title={Relational Verification Through Horn Clause Transformation},
  author={Emanuele De Angelis and Fabio Fioravanti and Alberto Pettorossi and Maurizio Proietti},
We present a method for verifying relational program properties, that is, properties that relate the input and the output of two programs. Our verification method is parametric with respect to the definition of the operational semantics of the programming language in which the two programs are written. That definition of the semantics consists of a set Int of constrained Horn clauses (CHCs) that encode the interpreter of the programming language. Then, given the programs and the relational… CONTINUE READING
