A discrete particle swarm optimization algorithm is proposed for solving traveling salesman problem

(TSP). It defines a newly velocity. It also defines some new operators between particle and velocity. A matrix, which keeps

the sorted ascending edges by distance for each city is created, and a variable size of gene pool is implemented to direct

the particle to search around the space. In this paper, some cases from TSPLIB are tested; the experiments results show that

Support Vector Machine(SVM) is developed on the frame of the statistical learning theory, which has been a new excellent machine learning method. SVM has solid theoretical foundation, clever algorithms. The outstanding performance of SVM depends on the choice of model parameters, including penalty parameter and kernel function parameter. In the paper, an improved Immune Genetic Algorithm(IGA) is applied to optimize the parameter of SVM. The experiment result proves that the method the paper proposed can reduce optimal time and improve the precision of classification largely compared to Grid searching when the classifier object is low dimension. When the classifier object is high dimension such as text data, the method can also reduce optimal time largely compared to Grid searching in the case of keeping same precision of classification.

The speed dynamic performance of a gasoline generator is an important factor that affects its electrical

performance. To tackle this problem, the paper analyzes the mathematical model of gasoline generator and control task， and

proposes a quasi sliding mode control algorithm， designs the conventional sliding mode controller， and the simulation of

speed control is implemented by MATLAB. The experimental results show that in guarantee the stability and dynamic of system

are unchanged, the control algorithm can largely reduce the system buffet. It is efficient in speed regulation for gasoline

generator

The college students’ status management system is designed based on the B/S structure. The open source database

MySQL is used for the backend database, PHP scripting is used in the serverside. The database is designed according to the

structure and functions of the system. The open source framework ADODB is used to connect the database and to access the

data. The related data can be batch imported and exported. The management of the college students’ status can be carried out

through the net and the connection is set up among the students management themselves, the management of the department and

the student affairs.
