This paper carries out the grade evaluation for college students according to the value of the synthetic evaluation by means of the optimal partition method of multivariate statistical analysis so as to get rid of the problems caused by the personal factors and enrich the theory of quantified grade evaluation for the college students.

Application of the optimum partition method for multi-variable and ordered geological data in engineering;

Based on core analysis and combined with the intraformation discrepance method, the extreme value point method, the maximum slope method and the optimum partition method, we use all kinds of logging data to a.

Addressing to deficiencies of this method,optimum partition method which is widely used in mass analysis is developed to fit thermocline boundary calculation.

The methods of diversity exponent, evenness exponent, richness, principal component analysis and optimal sorting method were used to study the community structure and temporal pattern of arthropods in cotton-alfalfa intercrop in Dunhuang.

The temporal structure of the communities was grouped into five continuous stages by using optimal sorting method,and the community characteristics at each stage were described.

On the basic analysis of evaluation techniques of regional competitiveness,application of ANN method and optimal segmentation,we develop a BP neural network model in regional competitiveness evaluation of Chinese iron and steel industry.

Application of Fisher optimal dissection method to flood season division;
