Econophysics and Sociophysics: Trends and Perspectives
(Wiley-VCH, 2006) Bikas K. Chakrabarti; Anirban Chakraborti; Arnab Chatterjee
Using tricks to handle coupled nonlinear dynamical many-body systems, several advancements have already been made in understanding the behavior of markets/economic/social systems and their dynamics. The book intends to provide the reader with updated reviews on such major developments in both econophysics and sociophysics, by leading experts in the respective fields. This is the first book providing a panoramic view of these developments in the last decade. © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
Performance of various cost functions in the search for strong S-Boxes
(IEEE Computer Society, 2006) Anirban Chakraborty; Arnab Chatterjee; S.K. Basu
We present the results of our search to find the performance of the various spectrum based cost functions and the effect of varying its parameter in the design of strong S-Boxes. It is conjectured that good S-Boxes can be obtained, if the search is made with the parameters R > 3.5 and X < 2n/2 and a more consistent performance can be expected if we use non-linearity spread as the annealing function. © 2006 IEEE.
