非线性整数规划的遗传算法Matlab程序

采用神经网络实现手写识别的一种方法，建立Bp神经网络，采用快速训练方法，可快速完成一类相关手写字体的模式识别，识别率较高，当字体变化较大识别率降低时，可重新训练具有较强的适应性。实验证实本方法较好实现了手写字符识别，但也存在识别速度较慢，有时训练不收敛等缺点(Handwriting recognition using neural network is a way to establish Bp neural network, using fast training methods, and can be related to the completion of a class of handwriting pattern recognition, recognition rate higher recognition rate when the font changed greatly reduced, they can re- Training has strong adaptability. Experiments confirmed that this method achieved a better handwritten character recognition, but there are also identified slow, and sometimes non-convergence of the training deficiencies)

实现云模型与分形的树模拟，用MATLAB和VB混合编程实现(achieve cloud model and fractal tree simulation with MATLAB and VB Programming)

说明：  在N=128时采用次优化迭代算法的PTS法与普通PTS法的PAPR性能比较。仿真参数：QPSK调制，V=4，P=4，取 。从程序的运行时间可知，采用次优化迭代算法，PTS法的复杂性可以大大降低。(In the N = 128 used sub-optimal iterative algorithm method and the general PTS PTS PAPR performance comparison method. Simulation parameters: QPSK modulation, V = 4, P = 4, to take. We can see from the program' s running time, using sub-optimal iterative algorithm, PTS method can greatly reduce the complexity.)
