Acceleration of SAT-Based Iterative Property Checking [chapter]

Daniel Große, Rolf Drechsler
2005 Lecture Notes in Computer Science  
In this paper we propose a new approach to speed up SAT-based iterative property checking.  ...  This process can be exploited by reusing conflict clauses in the corresponding SAT instances of consecutive property checking problems.  ...  In the last column the achieved speed-up is shown. As can be seen for the 100 cell arbiter in case of the property mutualexclusion no speed-up results.  ...

Grid-Based SAT Solving with Iterative Partitioning and Clause Learning [chapter]

Antti E. J. Hyvärinen, Tommi Junttila, Ilkka Niemelä
2011 Lecture Notes in Computer Science  
CL-SDSAT (time in s) Adding learning to the partition tree approach gives clear speed-up and solves more instances (left fig.)  ...  Many modern parallel SAT solvers are based on having several algorithms compete on solving the same instance.  ...  Iterative partitioning is an approach based on search space splitting which solves hard SAT instances, and Does not suffer from the increased expected run time problem Is faster than a comparable, efficient  ...

2013 2013 Formal Methods in Computer-Aided Design  
First, we demonstrate how to apply techniques used in the past to speed up resolution-based Group MUS extraction to plain MUS extraction.  ...  Second, we show that model rotation, presented in the context of assumption-based MUS extraction, can also be used with resolution-based MUS extraction.  ...  CONCLUSION We proposed a number of algorithms for speeding up MUS extraction. First, we adapted GMUS-oriented MUSbiased search algorithms to plain MUS extraction.  ...

Tuning the speed-accuracy trade-off to maximize reward rate in multisensory decision-making

Jan Drugowitsch, Gregory C DeAngelis, Dora E Angelaki, Alexandre Pouget
2015 eLife  
Furthermore, we show that deviations from the optimal speed/accuracy trade-off can be explained by assuming an incomplete gradient-based learning of these trade-offs.  ...  For decisions made under time pressure, effective decision making based on uncertain or ambiguous evidence requires efficient accumulation of evidence over time, as well as appropriately balancing speed  ...  that were adjusted to best explain the subjects' behavior. 101 In this follow-up study, we use the previously devised model to analyze 102 whether and how effectively human subjects adjust their SAT if  ...

Beyond decision! Motor contribution to speed–accuracy trade-off in decision-making

Laure Spieser, Mathieu Servant, Thierry Hasbroucq, Borís Burle
2016 Psychonomic Bulletin & Review  
Pointing to a speed-accuracy exchange within motor processes themselves, the present results call for a re-evaluation of widely accepted assumptions about SAT, and more generally, decision-making processes  ...  The present data challenges this largely accepted view, by directly showing that motor processes are speeded up under time pressure.  ...  As a consequence, SAT also occurs within the motor execution level, contributing to the global tradeoff both in terms of chronometry and of error rate, as speeding up motor execution increases the number  ...

Intra-National, Intra-Continental, and Intra-Planetary PPP

Charles M. Engel, Michael K. Hendrickson, John H. Rogers
1998 Social Science Research Network  
(3) Are speeds of adjustment toward PPP different for intra-national, cross-national and cross-continental real exchange rates?  ...  For example, can things be modeled so that our tests do not depend on the "base country"? (2) How should we handle correlation across real exchange rates in panel tests of PPP?  ...  Note that, using the assumptions already made, this assumption implies , each of the rows of this matrix is defined only up to a constant of proportionality.  ...

A Comprehensive Analytical Mathematic Model for Permanent-Magnet Synchronous Machines Incorporating Structural and Saturation Saliencies

Yi Wang, Jianguo Zhu, Youguang Guo
2010 IEEE transactions on magnetics  
Two parameters are defined to indicate these saliencies, i.e. the structural saliency ratio (K str ) and the saturation saliency ratio (K sat ).  ...  Then the inductance matrix in stationary frame can be rewritten as a function of K sat , which can be determined by the current value based on the look up table shown in Table I .  ...  The errors of the speed and current mainly come from the friction coefficient of the model and the assumptions made in the proposed mathematic model. VII.  ...

Critical examination of constraints on the equation of state of dense matter obtained from GW170817

I. Tews, J. Margueron, S. Reddy
2018 Physical Review C  
Our models are constrained by calculations of the neutron-matter EOS using chiral effective field theory Hamiltonians with reliable error estimates up to once or twice the nuclear saturation density.  ...  distinct extrapolations to higher density: a minimal model (MM) which assumes that the EOS is a smooth function of density described by a Taylor expansion and a more general model parametrized by the speed  ...  Thus, we base all our models on the neutron-matter EOS up to n tr , which we vary to be n sat or 2n sat .  ...

Using unsatisfiable cores to debug multiple design errors

Andre Suelflow, Goerschwin Fey, Roderick Bloem, Rolf Drechsler
2008 Proceedings of the 18th ACM Great Lakes symposium on VLSI - GLSVLSI '08  
In comparison to standard SAT-based debugging, the experimental results show a significant speed-up for debugging multiple faults.  ...  Unsatisfiable cores contained in a SAT instance for debugging are used (1) to determine all suspects, and (2) to speed-up the debugging process.  ...  Due to this reduction speed-ups of up to 2.83 of the total diagnosis run time were achieved.  ...
