Factoring polynomials with rational coefficients

by A. K. Lenstra, H. W. Lenstra , L. Lovasz - MATH. ANN , 1982
"... In this paper we present a polynomial-time algorithm to solve the following problem: given a non-zero polynomial fe Q[X] in one variable with rational coefficients, find the decomposition of f into irreducible factors in Q[X]. It is well known that this is equivalent to factoring primitive polynomia ..."

Reasoning the fast and frugal way: Models of bounded rationality.

by Gerd Gigerenzer , Daniel G Goldstein - Psychological Review, , 1996
"... Humans and animals make inferences about the world under limited time and knowledge. In contrast, many models of rational inference treat the mind as a Laplacean Demon, equipped with unlimited time, knowledge, and computational might. Following H. Simon's notion of satisncing, the authors have ..."

Epidemic Spreading in Scale-Free Networks

by Romualdo Pastor-satorras, Alessandro Vespignani , 2000
"... The Internet, as well as many other networks, has a very complex connectivity recently modeled by the class of scale-free networks. This feature, which appears to be very efficient for a communications network, favors at the same time the spreading of computer viruses. We analyze real data from c ..."

The Spring Kernel: A New Paradigm for Real-Time Systems

by John A. Stankovic, Krithi Ramamritham - IEEE Software , 1991
"... Next generation real-time systems will require greater flexibility and predictability than is commonly found in today's systems. These future systems include the space sta-tion, integrated vision/robotics/AI systems, collections of humans/robots coordinating to achieve common objectives (usuall ..."

(usually in hazardous environments such as undersea explo-ration or chemical plants), and various command and control applications. The Spring kernel is a research oriented kernel designed to form the basis of a flexible, hard real-time operating system for such applications. Our approach challenges

Reasoning about beliefs and actions under computational resource constraints

by Eric J. Horvitz - in Proceedings of the 1989 Workshop on Uncertainty and AI , 1987
"... Although many investigators arm a desire to build reasoning systems that behave consistently with the axiomatic basis dened by probability theory and utility theory, limited resources for engineering and computation can make a complete normative anal-ysis impossible. We attempt to move discussion be ..."

alternative approximation procedures and heuristics for computation and knowledge acquisition. We discuss how knowledge about the structure of user utility can be used to control value tradeos for tailoring inference to alternative contexts. We address the notion of real-time rationality, focusing

Developments in the Measurement of Subjective Well-Being

by Daniel Kahneman , Alan B Krueger - Psychological Science. , 1993
"... F or good reasons, economists have had a long-standing preference for studying peoples' revealed preferences; that is, looking at individuals' actual choices and decisions rather than their stated intentions or subjective reports of likes and dislikes. Yet people often make choices that b ..."

and remembered utility; that is, the way people feel about experiences in real-time and the way they remember their experiences after they are over. The participants in experiments in which a physical stimulus is varied generally provide profiles that are similar, both in level and in shape, and that respond

The Psychophysiology of Real-Time Financial Risk Processing.”

by Andrew W Lo , Dmitry V Repin - Journal of Cognitive Neuroscience, , 2002
"... Abstract & A longstanding controversy in economics and finance is whether financial markets are governed by rational forces or by emotional responses. We study the importance of emotion in the decision-making process of professional securities traders by measuring their physiological characteri ..."

Modeling of Real-Time Systems in UML with Rational Rose and Rose Real-time Based on RUP

by Magnus Antonsson, et al. , 2001
"... on RUP In software development, using UML for modeling of real-time systems is a fairly new area. There are a lot of different theories and reports in this area and UML is in a development phase when it comes to modeling of real-time systems. This report provides a summary of how and why UML and UML ..."

and UML-RT can be used for modeling of real-time systems. It also includes a summary of the advantages and disadvantages of Rational Rose and Rose-RT concerning modeling of real-time systems. This report also provides modifications that can be done to RUP to make the process better suited for development

Monotone Rational Series And Max-Plus Algebraic Models Of Real-Time Systems

by Albert Benveniste, Stéphane Gaubert, Claude Jard - in "Proc. of the Fourth Workshop on Discrete Event Systems (WODES98 , 1998
"... In the modelling of timed discrete event systems, one traditionally uses dater functions, which give completion times, as a function of numbers of events. Dater functions are non-decreasing. We extend this modelling to the case of multiform logical and physical times, which are needed to model concu ..."

Controlling the Learning Process of Real-Time Heuristic Search

by Masashi Shimbo, Toru Ishida , 2003
"... Real-time search provides an attractive framework for intelligent autonomous agents, as it allows us to model an agent's ability to improve its performance through experience. However, the behavior of real-time search agents is far from rational during the learning (convergence) process, in tha ..."
