基于matlab的蚁群算法LF解决聚类问题(matlab ants clusting)

matlab 代码，利用分步傅里叶方法求解NLSE方程(matlab code, solve the equation NLSE)

通过实现文件ft1调用函数fseries，完成傅里叶级数实现.(realization of fourier series by implemention of the file ft1,doing the function fseries)

说明：  简易SSB设计 有详细的报告和说明，可以作为参考(Simple SSB detailed design reports and notes, can be used as reference)

this is the matlab program of dvb transmission and reception of ofdm signals

IT IS THE CODE FOR LEACH PROTOCOL. LEACH IS THE ENERGYY EFFICIENT ROUTING PROTOCOL WHICH IS MOST WIDELY USED IS SMALL AREA NETWORKS

一个基于阈值的粒子比较准则，用于处理多目标约束优化问题,该准则可以保留一部分序值较小且约束违反度在允许范围内的不可行解微粒,从而达到由不可行解向可行解进化的目的；一个新的拥挤度函数,使得位于稀疏区域和Pareto前沿边界附近的点有较大的拥挤度函数值,从而被选择上的概率也较大 从而构成解决多目标约束优化问题的混合粒子群算法。(A comparison based on the threshold criteria for the particle to handle multi-objective constrained optimization problem, part of the guidelines can keep order value is small and the constraint violation in allowing infeasible solutions within the particles, so as to achieve a feasible solution to the infeasible solution The purpose of evolution a new function of crowding, making the Pareto front in the sparse region and near the border points have a greater value of the congestion function, which is the larger the probability of selection so as to constitute solve multi-objective constrained optimization problems hybrid particle swarm algorithm.)

本源程序提供在AWGN信道下的bpsk调制方式的仿真，并与理论曲线作比较，得到了理想的结果(This source provides bpsk under the AWGN channel modulation of the simulation, and compared with the theoretical curve obtained satisfactory results)

关于蚁群算法的tsp问题应用到配电网检修计划优化中(Tsp issue on ant colony algorithm applied to the optimization of distribution network overhaul plan)

hough变换求图像中的直线，matlab语言编写，修改图片的路径即可。(hough transform to draw the lines in the picture,writen by matlab, the code can only be used after modify the path of the picture.)
