A remarkable characteristic of human beings is their tendency to form societies. That put themselves in a social position, where they interact with the environment and try to convince others of their own convictions. This study proposes a model for interactions among individuals of a society, accompanying the evolution of their opinions over time. We consider a situation where the individuals are...
A multiagent system (MAS) is a computer based model of multiple interacting intelligent agents within an environment. One of the key aspects of such models is the ability to reproduce the results in different software and hardware. In general, the simulation of these models are carried out under floating point standards. It is well known that by limitation of computer arithmetic, the results may be...
Nowadays, a dataset includes a huge number of features with irrelevant and redundant ones. Feature selection is required for a better machine-learning algorithms' performance. A system for feature selection is proposed in this work using a sine cosine algorithm (SCA). SCA is a new stochastic search algorithm for optimization problems. SCA optimization adaptively balances the exploration and exploitation...
This paper investigates the potential of evolutionary algorithms, developed by the combination of genetic programming (GP) and automatic differentiation methods (AD), in determining analytic solutions to ordinary and partial differential equations (ODE and PDE). In turn, AD is a set of techniques based on the mechanical application of the chain rule to numerically evaluate the derivative of a function...
This paper focuses on the coordination of a population of thermostatically controlled loads (TCLs) with unknown parameters to achieve group objectives. The problem involves designing the device bidding and market clearing strategies to motivate self-interested users to realize efficient energy allocation subject to a peak energy constraint. This coordination problem is formulated as a mechanism design...
In this work, a mathematical model has been developed to analyze the spread of a distributed attack on critically targeted resources in a network using firewall security coefficient. The model provides an epidemic framework with two sub-frameworks to consider the difference between the overall behavior of the attacking population and the targeted population. The targeted population and attacking population...
The research of stare is useful for country and people. A space share rising statistical parallel model is built by using statistical theory. The formula of correlation between stock prices is given. The regression equation with space coordination is obtained.
Stage structured based population models have found many applications in the recent years. In this paper an age structured population model is developed and implemented to study the trends in the computer and video game playing population of US. The entire game paying population is divided into three compartments on the basis of the age group to which they belong. After simulating the mathematical...
How and why cooperation develops in human populations is not known. The iterated prisoner's dilemma game provides a natural framework for studying cooperation growth in human populations. However, recent experiments with human subjects has exposed a number of serious flaws in virtually all of the game-theoretical models that have appeared in the literature. Indeed, some experiments suggest network...
We build a model for the kind of decision making involved in games of strategy such as chess, making it abstract enough to remove essentially all game-specific contingency, and compare it to known psychometric models of test taking, item response, and performance assessment. Decisions are modeled in terms of fallible agents Z faced with possible actions ai whose utilities Ui=U (ai) are not fully apparent...
Cooperation in nature is a complex topic and its study has left scientists with many open questions. Over the past two decades research has been undertaken into how cooperation works in an evolutionary context and how we can emulate it for social analysis. Numerous computer models have been developed and analyzed, with many models formulated as spatial or network games. These games use various update...
