Interactive learning-based realizability for Heyting arithmetic with EM1

F Aschieri, S Berardi - Logical Methods in Computer Science, 2010 - lmcs.episciences.org
We apply to the semantics of Arithmetic the idea of``finite approximation''used to provide
computational interpretations of Herbrand's Theorem, and we interpret classical proofs as …

Games with 1-backtracking

S Berardi, T Coquand, S Hayashi - Annals of Pure and Applied Logic, 2010 - Elsevier
We associate with any game G another game, which is a variant of it, and which we call bck
(G). Winning strategies for bck (G) have a lower recursive degree than winning strategies for …

Learning, realizability and games in classical arithmetic

F Aschieri - arXiv preprint arXiv:1012.4992, 2010 - arxiv.org
In this dissertation we provide mathematical evidence that the concept of learning can be
used to give a new and intuitive computational semantics of classical proofs in various …

Interactive realizers: a new approach to program extraction from nonconstructive proofs

S Berardi, U de'Liguoro - ACM Transactions on Computational Logic …, 2012 - dl.acm.org
We propose a realizability interpretation of a system for quantier free arithmetic which is
equivalent to the fragment of classical arithmetic without nested quantifiers, called here EM 1 …

Interactive Realizability, Monads and Witness Extraction

G Birolo - arXiv preprint arXiv:1304.4091, 2013 - arxiv.org
In this dissertation we collect some results about" interactive realizability", a realizability
semantics that extends the Brouwer-Heyting-Kolmogorov interpretation to (sub-) classical …

Proofs as stateful programs: A first-order logic with abstract Hoare triples, and an interpretation into an imperative language

T Powell - Logical Methods in Computer Science, 2024 - lmcs.episciences.org
We introduce an extension of first-order logic that comes equipped with additional
predicates for reasoning about an abstract state. Sequents in the logic comprise a main …

Game semantics and the geometry of backtracking: A new complexity analysis of interaction

F Aschieri - The Journal of Symbolic Logic, 2017 - cambridge.org
We present abstract complexity results about Coquand and Hyland–Ong game semantics,
that will lead to new bounds on the length of first-order cut-elimination, normalization …

Interactive learning based realizability and 1-backtracking games

F Aschieri - arXiv preprint arXiv:1101.5441, 2011 - arxiv.org
We prove that interactive learning based classical realizability (introduced by Aschieri and
Berardi for first order arithmetic) is sound with respect to Coquand game semantics. In …

Knowledge Spaces and the Completeness of Learning Strategies

S Berardi, U de'Liguoro - Logical Methods in Computer …, 2014 - lmcs.episciences.org
We propose a theory of learning aimed to formalize some ideas underlying Coquand's game
semantics and Krivine's realizability of classical logic. We introduce a notion of knowledge …

Interactive Realizers and Monads

S Berardi, U de'Liguoro - arXiv preprint arXiv:1005.2907, 2010 - arxiv.org
We propose a realizability interpretation of a system for quantifier free arithmetic which is
equivalent to the fragment of classical arithmetic without" nested" quantifiers, called here …
