Emanuele De Angelis, Fabio Fioravanti, Alberto Pettorossi +1
The functional properties of a program are often specified by providing a contract for each of its functions. A contract of a function consists of a pair of formulas, called a prec…
Multiple Query Satisfiability of Constrained Horn Clauses
Emanuele De Angelis, Fabio Fioravanti, Alberto Pettorossi +1
We address the problem of checking the satisfiability of a set of constrained Horn clauses (CHCs) possibly including more than one query. We propose a transformation technique that…
Verifying Catamorphism-Based Contracts using Constrained Horn Clauses
Emanuele De Angelis, Fabio Fioravanti, Alberto Pettorossi +1
We address the problem of verifying that the functions of a program meet their contracts, specified by pre/postconditions. We follow an approach based on constrained Horn clauses (…
