On Computational Tractability for Rational Verification

Julian Gutierrez, Muhammad Najib, Giuseppe Perelli, Michael Wooldridge
2019 Proceedings of the Twenty-Eighth International Joint Conference on Artificial Intelligence  
Rational verification can be understood as a counterpart of model checking for multiagent systems, but while model checking can be done in polynomial time for some temporal logic specification languages  ...  In particular, we show that for a number of relevant settings, rational verification can be done in polynomial space or even in polynomial time.  ...  Proceedings of the Twenty-Eighth International Joint Conference on Artificial Intelligence  ...

Model Checking Hybrid Systems [chapter]

Edmund M. Clarke, Sicun Gao
2014 Lecture Notes in Computer Science  
We present the framework of delta-complete analysis for bounded reachability problems of hybrid systems.  ...  Our implementation of the techniques scales well on several highly nonlinear hybrid system models that arise in biomedical applications.  ...  We can now develop a new framework for solving bounded reachability problems for hybrid systems based on solving δ-decisions.  ...

Intractability and the use of heuristics in psychological explanations

Iris van Rooij, Cory D. Wright, Todd Wareham
2010 Synthese  
We then propose computational-level theory revision as a principled and workable alternative.  ...  cognitive scientists, having discovered that some computationallevel characterization f of a cognitive capacity φ is intractable, invoke heuristics as algorithmic-level explanations of how cognizers compute  ...  Verification of tractability, by means of mathematical proof, is indispensable for cognitive scientists that hope to devise tractable computational-level characterizations of cognitive capacities.  ...

TRACTABLE FALSIFIABILITY

Ronen Gradwohl, Eran Shmaya
2015 Economics and Philosophy  
We consider several variants of the definition of 'short proof' and several assumptions about the difficulty of computation, and study their different implications on the falsifiability of theories.  ...  We model the concept of a short proof using tools from computational complexity, and provide some examples of economic theories that are falsifiable in the usual sense but not with this additional requirement  ...  See Goldreich (2008) or any other textbook on computational complexity for further details.  ...

Tractable Rational Map Signature [chapter]

Lih-Chung Wang, Yuh-Hua Hu, Feipei Lai, Chun-Yen Chou, Bo-Yin Yang
2005 Lecture Notes in Computer Science  
We present a new multivariate digital signature scheme (TRMS) based on tractable rational maps.  ...  Digital signature schemes are crucial for applications in electronic commerce. The effectiveness and security of a digital signature scheme rely on its underlying public key cryptosystem.  ...  For any point in the image set of S, it is very easy to find point-wise inverse for tractable rational maps: Given a point (y 1 , y 2 , . . . , y n ) ∈ ϕ(S), we can easily compute (x 1 , x 2 , . . . ,  ...

Rational verification: game-theoretic verification of multi-agent systems

Alessandro Abate, Julian Gutierrez, Lewis Hammond, Paul Harrenstein, Marta Kwiatkowska, Muhammad Najib, Giuseppe Perelli, Thomas Steeples, Michael Wooldridge
2021 Applied intelligence (Boston)  
After motivating and introducing the overall framework of rational verification, we discuss key results obtained in the past few years as well as relevant related work in logic, AI, and computer science  ...  AbstractWe provide a survey of the state of the art of rational verification: the problem of checking whether a given temporal logic formula ϕ is satisfied in some or all game-theoretic equilibria of a  ...  Through our work on rational verification, we also address this gap in the literature of verification for AI systems.  ...

Holism, or the Erosion of Modularity - a Methodological Challenge for Validation

Johannes Lenhard
2018 Philosophy of Science  
The resulting problem for validating models is one of holism. The argument will proceed by analyzing the techniques of parameterization, tuning, and kludging.  ...  Finally, I will ask in what circumstances this might be sufficient for model validation.  ...  This perspective suggests the computer would enlarge the tractability of complex systems due to its vast capacity for handling (algorithmic) mechanisms.  ...

SVM Speaker Verification using an Incomplete Cholesky Decomposition Sequence Kernel

Jerome Louradour, Khalid Daoudi, Francis Bach
2006 2006 IEEE Odyssey - The Speaker and Language Recognition Workshop  
The Generalized Linear discriminant Sequence (GLDS) kernel has been showing to provide very good performance in SVM speaker verification in NIST SRE evaluations.  ...  We present experiments on the Biosecure project data. The results show that our new sequence kernel outperforms the GLDS one as well as the one developed in our recent work.  ...  An interesting problem then is to find a tractable way to compute or approximate (1) for any p.  ...

Rational Sumchecks [chapter]

Siyao Guo, Pavel Hubáček, Alon Rosen, Margarita Vald
2015 Lecture Notes in Computer Science  
The advantage of rational proofs over their classical counterparts is that they allow for extremely low communication and verification time. In recent work, Guo et al.  ...  We extend the Guo et al. result by constructing a single-round delegation scheme with sublinear verification for all languages in P.  ...  This is done by first transforming the rational interactive proof for NC to RMIP (with only negligible loss in the reward gap) and then applying Theorem 8 on the resulted RMIP.  ...
