depend upon explanation in order to " make sense " out of our world. And, making sense is all the more important when dealing with change. But, what happens if our explanations are wrong? This question is examined with respect to two types of explanatory model. Models based on labels and categories we shall refer to as " representations. " More complex models involving stories, multiple algorit...

This paper analyzes a preference revelation game in the student optimal deferred acceptance algorithm in a college admission problem. We assume that each college’s true preferences are known publicly and analyze the strategic behavior of students. We show the existence of a strictly strong Nash equilibrium in the preference revelation game by providing a simple algorithm that finds it. In parti...

‎Our contribution in this paper is to propose an iterative algorithm which does not require prior knowledge of operator norm and prove a strong convergence theorem for approximating a solution of split equality fixed point problem for quasi-nonexpansive mappings in a real Hilbert space‎. ‎So many have used algorithms involving the operator norm for solving split equality fixed point problem‎, ‎...

Adaptive networks include a set of nodes with adaptation and learning abilities for modeling various types of self-organized and complex activities encountered in the real world. This paper presents the effect of heterogeneously distributed incremental LMS algorithm with ideal links on the quality of unknown parameter estimation. In heterogeneous adaptive networks, a fraction of the nodes, defi...

In this paper, we have examined abrupt changes in volatility of TEPIX index in Tehran stock exchange during August 23, 2010 to June 12, 2014. Applying the iterated cumulative sum of squares (ICSS) algorithm proposed by Inclan and Tiao (1994) and the modified version of this algorithm consisting Kappa 1 and Kappa 2 test statistics developed by Sansó et al. (2004), we have specified that the dete...

In this paper, we propose a genetic algorithm, called GenSPN, for finding highly probable differential characteristics of substitution permutation networks (SPNs). A special fitness function and a heuristic mutation operator have been used to improve the overall performance of the algorithm. We report our results of applying GenSPN for finding highly probable differential characteristics of Ser...

There are two sources for governments to raise their revenues. The first is the direct taxation levied on output, and the second is seigniorage. Seigniorage is also known as printing new money and is defined as the value of real resources acquired by the government through its power of sovereignty on its monopoly of printing money. The purpose of this paper is to examine the Laffer curve for Se...
