Local Completeness for Program Correctness and Incorrectness (Invited Talk)

Authors: Roberto Bruni

Published in: LIPIcs, Volume 270, 10th Conference on Algebra and Coalgebra in Computer Science (CALCO 2023)


Abstract
Program correctness techniques aim to prove the absence of bugs, but can yield false alarms because they tend to over-approximate program semantics. Vice versa, program incorrectness methods are aimed to detect true bugs, without false alarms, but cannot be used to prove correctness, because they under-approximate program semantics. In this invited talk we will overview our ongoing research on the use of the abstract interpretation framework to combine under- and over-approximation in the same analysis and distill a logic for program correctness and incorrectness.

Summary 3: On Graph(ic) Encodings

Authors: Roberto Bruni and Ivan Lanese

Published in: Dagstuhl Seminar Proceedings, Volume 4241, Graph Transformations and Process Algebras for Modeling Distributed and Mobile Systems (2005)


Abstract
This paper is an informal summary of different encoding techniques from process calculi and distributed formalisms to graphic frameworks. The survey includes the use of solo diagrams, term graphs, synchronized hyperedge replacement systems, bigraphs, tile models and interactive systems, all presented at the Dagstuhl Seminar 04241. The common theme of all techniques recalled here is having a graphic presentation that, at the same time, gives both an intuitive visual rendering (of processes, states, etc.) and a rigorous mathematical framework.
