Genetic algorithm (GA) is a kind of method to simulate the natural evolvement process to search the optimal solution, and the algorithm can be evolved by four operations including coding, selecting, crossing and variation. The particle swarm optimization (PSO) is a kind of optimization tool based on iteration, and the particle has not only global searching(More)
This study's objective is to solve mining knowledge issue from different sources of distributed, formatted or unformatted data with diverse data semantics. The issue is formulated as data mining in knowledge grid. In particular, this paper presented a DM-GRID (data mining in grid) model based on software architecture of a novel infrastructure for(More)
This paper presents an economic-based resource allocation algorithm - mix optimization algorithm to meet user requirements in proportional resource sharing grid environment. The mix optimization algorithm is targeted to minimize two objectives, i.e., competing users 'processing cost and competing users' executing time with budget and deadline constraints,(More)
Conditional distribution reflects the dependency link among random variables, but two-dimensional random variables Conditional Distribution has some limitations. In order to rich the content of conditional distribution this paper gives the extension of conditional distribution and examples in the case of continuous random variables. For the given definition(More)
This study’s objective is to solve performance evaluation problem of PC cluster in processing seismic data intensive computing. The objective of performance evaluation is determining the relationship between the number of PC node and the scale of tasks to be processed to decide whether the transaction of seismic data processing should be transformed from(More)
This study's objective is to solve the dynamic linkages and mechanism problem between exchange rates and stock prices. This paper examines the relationship between RMB-Dollar exchange rates and 5 market indexes and 19 industrial indexes of China stock market by cointegration test and Granger causality test. The empirical results show a significant long-term(More)
Though the divide-and-conquer algorithm is a powerful technology, but it is difficult to be used in practice, so the design of this algorithm should be regulated in the teaching. In this article, the teaching process and the characters of the divide-and-conquer algorithm are studied when solving the problem of chessboard coverage. Aiming at the deficiency(More)
