说明：  最基础的灰色预测的matlab源程序，可以直接运行(Grey prediction program by matlab)

This paper is the result of a literature study carried out by the authors. It is a review of the dierent attempts made to solve the Travelling Salesman Problem with Genetic Algorithms. We present crossover and mutation operators, developed to tackle the Travelling Salesman Problem with Genetic Algorithms with dierent representations such as: binary representation, path representation, adjacency representation, ordinal representation and matrix representation. Likewise, we show the experimental results obtained with dierent standard examples using combination of crossover and mutation operators in relation with path representation. Keywords: Travelling Salesman Problem Genetic Algorithms Binary representation Path representation Adjacency representation Ordinal representation Matrix representation Hybridation. 1 1 Introduction In nature, there exist many processes which seek a stable state. These processes can be seen as natural optimization processes. Over the last...

PSO粒子群算法在系统辨识中的matlab仿真源程序(PSO PSO in system identification matlab source)

本程序可以进行主层分分析，将因素在轴上进行投影，选择几个贡献率比较大因子(This procedure can be the main floor sub-analysis, factor in the axis for projection, choose the contribution rate of a few relatively large factor)

说明：  16QAM的数字通信系统的仿真，包括调制解调，上下变频，加入了高斯白噪声，并且每个步骤都生成相应的图形(16QAM digital communication system simulation, including the modulation and demodulation, frequency conversion from top to bottom, by adding a Gaussian white noise, and each step to generate the corresponding graphics)

说明：  产生BPSK基带数字信号的时域波形。其中基带数字信号的传输速率以及每个码元周期内载波的周期数可以设置。(To generate the time-domain wave for BPSK. And the transmitting rate and the frequency of the carrier can both be set in the program.)
