Testing Consumer Rationality using Perfect Graphs and Oriented Discs [article]

Shant Boodaghians, Adrian Vetta
2015 arXiv   pre-print
Specifically, for two-commodity markets the consumer rationality problem is polynomial time solvable; we prove this via a reduction to the vertex cover problem on perfect graphs.  ...  Given a consumer data-set, the axioms of revealed preference proffer a binary test for rational behaviour.  ...  This completes all the steps in the reduction and we obtain: The consumer rationality problem is NP-complete for a market with at least 3 commodities.  ...

Testing Consumer Rationality Using Perfect Graphs and Oriented Discs [chapter]

Shant Boodaghians, Adrian Vetta
2015 Lecture Notes in Computer Science  
For three-commodity markets, however, the problem is NP-complete; we prove this using a reduction from planar 3-sat that is based upon oriented-disc drawings.  ...  Given a consumer data-set, the axioms of revealed preference proffer a binary test for rational behaviour.  ...  A Measure of Consumer Rationality We have seen that graph acyclicity can be used to provide a test for consumer rationality.  ...

Pull Off test to evaluate the compressive strength of concrete: an alternative to Brazilian standard techniques

E. Pereira, M. H. F. de Medeiros
2012 Revista IBRACON de Estruturas e Materiais  
The aim of this paper is to analyze the use of Pull Off test as an inspection tool of concrete and also disclose the possibility of use of complementary techniques to the standard ones in Brazil.  ...  In Brazil, the standard tests for this purpose are: Compressive test in drilled cores, rebound hammer test and ultrasonic test. In the United States and Europe are also regulated other techniques.  ...  In addition to the composition and concrete properties, also have influence the variation on the rupture surface, the orientation and position of the aggregate onto the disc, the disc material (steel or  ...

Limit Order Strategic Placement with Adverse Selection Risk and the Role of Latency [article]

Charles-Albert Lehalle, Othmane Mounjid
2018 arXiv   pre-print
In a third part we show how the added value of exploiting a knowledge on liquidity imbalance is eroded by latency: being able to predict future liquidity consuming flows is of less use if you have not  ...  There is thus a rational for market makers to be as fast as possible as a protection to adverse selection.  ...  Authors would like to thank Sasha Stoïkov and Jean-Philippe Bouchaud for discussions about orderbook dynamics and optimal placement of limit orders that motivated this paper.  ...

Fluctuations in the Aztec diamonds via a Lorentz-minimal surface [article]

Dmitry Chelkak, Sanjay Ramassamy
2021 arXiv   pre-print
This surface naturally appears as the limit of the graphs of origami maps associated to symmetric t-embeddings of Aztec diamonds, fitting the framework recently developed in arXiv:2109.06272.  ...  We would like to thank Benoît Laslier and Marianna Russkikh for many discussions and comments on draft versions of this note, and Jesper Lykke Jacobsen, Gregg Musiker and Istvan Prause for pointing out  ...  In [6] , the notion of a perfect t-embedding or simply p-embeddings of finite graphs is introduced.  ...

The Superintelligent Will: Motivation and Instrumental Rationality in Advanced Artificial Agents

Nick Bostrom
2012 Minds and Machines  
In combination, the two theses help us understand the possible range of behavior of superintelligent agents, and they point to some potential dangers in building such an agent.  ...  This paper discusses the relation between intelligence and motivation in artificial agents, developing and briefly arguing for two theses.  ...  What is predictable is that the convergent with a higher expected utility, the agent would keep testing and re-testing (and keep acquiring more resources to enable these tests). instrumental values would  ...
