Simplorer_Maxwell联合仿真.zip
这方面的资料实在少得可怜,只能自己总结一些经验。准备分享一下,同时也是以防以后再被类似的问题卡住。(有可能有些小错误,毕竟第一次弄,发现问题可以私信我)里面是PMSM的弱磁控制,因为考虑仿真时间比较长,我把仿真结果也一起放进去了,打开应该能直接看结果,有3000rpm和8000rpm,我的博客里有相关讲解。

分支定界法求解纯整数或混合的整数规划问题.
设有最大化的整数规划问题A,与它对应的线性规划为问题B,从解问题B开始,若其最优解不符合A 的整数条件,那么B的最优目标函数必是A 的最优目标函数 的上界,记作Z1;而A 的任意可行解的目标函数值将是 一个下界Z2。分支定界法就是将B的可行域分成子区域(称为分支),逐步减小Z1和增大Z2,最终求到 .

python写的基于感知机的中文分词系统
基于字的用感知机实现的中文分词系统。完全训练后对微软的测试集精度可以达到96%多。我上传的版本是完整的代码(训练和分词),大家自己用附带的微软训练数据训练就可以了,只有一个文件。 代码总的来说写的还是很清楚的,方便自己也方便别人阅读。欢迎大家共讨论,xiatian@ict.ac.cn。
