重写了微软提供SQLHelper(共用的数据库调用接口) 1把SqlHelper的connectionString做成一个全局量,统一设置数据库连接字符串 2增加了返回特定表名的DataSet的各接口。 可在项目的config文件设置数据库连接字符串 private static string connectionString = System.Configuration.ConfigurationSettings.AppSettings["ConnectionString"] 当然可以把数据库连接方法修改后直接用。-rewritten Microsoft SQLHelper (shared database Call Interface) a SqlHelper the connectionString caused an overall volume, uniform database connections increased by two strings to the specific name of the table in the DataSet interface. In the config files set database connection string private static string connectionString = System.Configuration.ConfigurationSettings.AppSettings [ "ConnectionString"] lt; !-- Application specific settings-- gt; Lt; AppSettingsgt; Lt; Add key

遗传算法C
很好用的c
注:前两个文件存储为m文件并放在工作目录下,运行结果为
p =
0.0000 -0.0000 0.0055
大家可以直接绘出f(x)的图形来大概看看f(x)的最值是多少,也可是使用优化函数来验证。matlab命令行执行命令:
fplot("x+10*sin(5*x)+7*cos(4*x)",[0,9])
evalops是传递给适应度函数的参数,opts是二进制编码的精度,termops是选择maxGenTerm结束函数时传递个maxGenTerm的参数,即遗传代数。xoverops是传递给交叉函数的参数。mutops是传递给变异函数的参数。
