The Traveling Salesman Problem is one of the most intensively studied problems in computational mathematics. Due to the basic genetic algorithm convergence speed is slow, easy to stagnation. We present in this paper a new improved mutation strategy to solve this problem. Roulette wheel selection strategy is used to avoid running into trap of the part best value. And simulated niche method is introduced...
Using 2,116 observations from 2007 to 2008, we investigate the relation of accounting conservatism and cost of equity capital, and the influence of property rights on it. We find accounting conservatism is negatively related to equity cost and state ownership lower the influence of conservatism on cost of equity capital.
In Internet era, instant messaging software are closely linked with Net users. However, with enormous growth of instant messaging software users, a lot of lawbreakers carry out criminal activities using them as a medium. Then, mining and analyzing the useful clues from raw data left on the computer has become a significant means and research area for investigation and forensics. In this paper, taking...
Nowadays, E-mail communication has been abused for numerous illegitimate purposes such as E-mail spamming, terrorist attack, business fraud, etc. As a result, to analysis the rich personal information hidden in E-mail is significant for investigation and evidence collection. In this paper, an investigation and analysis system aiming to Email was presented, which supports a variety of data sources...
This paper has made a thorough analysis of brushless DC motor simulation system, in which we use a single neuron PID control algorithm based on RBF neural network for on-line identification (RBF-PID Algorithm). A special human-computer interaction (HCI) interface was designed in this paper, which provides interface for users to set the correlative parameters and select related control algorithm. Two...
The data file of downloading records in the P2P downloading software contain the rich personal information. So mining and analyzing the useful clues inside has become a significant means and research area for the computer investigation and forensics. The Thunder which is the typical representative of P2P downloading software and the most popular in China has been emphatically analyzed in this paper,...
At present, keypad electronic lock with alarming function is to gradually replace the traditional mechanical locks, overcoming the shortcoming of the traditional mechanical locks which contain few password and lack of reliability, but keypad electronic lock makes a great progress in terms of technology and performance.This paper represents a type of remote-controlled electronic lock developed with...
This paper addresses the graph drawing problem for email networks. First, the graph drawing problem is formulated as a minimization problem. Then, a genetic algorithm based graph drawing method is proposed by solving the minimization problem. By taking into account the smallworld property of the email-networks, the proposed method improved the force-directed graph drawing algorithm to draw the graph...
N-Queen problem is a typical combination optimization problem and it belongs among NP-hard problems. Its common solution is recursive algorithm. When the problem is complex, it will cost much more time for solution. Compared with the recursive algorithm, genetic algorithm can be component for the complex situation. In view of this, a hybrid genetic algorithm was presented in this paper to solve the...
The agenda database file, stored in the telephony, is rich of personal information. Analyzing and extracting the useable clues is very significant for case-investigation and evidence-gaining. First of all, it is necessary to analyze the data structure of the database files and retrieve the information. In this paper, I find out the data structure of agenda files, on the IDE-- Carbide C++ developed...
This paper, based on the relation between granule and binary numeral [8] and the transforming relation between granule computing and binary numeral operations, obtained the rough certainty factor and may affecting scope factor through simple binary bit-operations (ie AND and XOR).Hence, we tried to extract rules in DT automatically. The method we proposed has two advantages: (1) No need to set an...
This paper put the rough set methodology based on the information table disposal to expand the dual (binary) relations described by the neighborhood system. To make full use of logic operations including AND operation by-bit, XOR operation by-bit and NOR operation by-bit, gains the certain and uncertain information among the various decision-making factors. The use of knowledge related with Grey system...
By analyzing Vague Sets voting model, we bring forth a new method for approximating Vague Sets to Fuzzy Sets, and its general process is presented in the article. In a voting model, firstly, we suppose that the abstainers must vote for once more, and the results are close studied. Then the randomicity, uncertainty, and conformity of voting are found. As we know, an abstainer may favor somebody, oppose...
A method for the production scheduling based on the network is put forward in this paper. It is suitable for the production arranging for those complicated products that have a lot of procedures and long production lead-time and are generally put into production in one unit. It is proved that the method improves the agility and efficiency of arranging shop production schedule. The production is carried...
