在窗体上绘制一个名称为Command1的命令按钮，然后编写如下程序： Option Base 1 Private Sub Commandl_Click() Dim c As Integer，d As Integer d=0 c=6 x=Array(2，4，6，8，10，12) For i=1 To 6 If x(i)＞c Then d=d+x(i) c=x(i) Else d=d-c End If Next i Print d End Sub 程序运行后，如果单击命令按钮，则在窗体上输出的内容为
D.20

未分类题设有如下程序： Private Sub Command1_Click() Dim C As Integer， d As Integer c=4 d=InputBox(“请输入一个整数”) Do While d＞0 If d＞c Then c=c+1 End If d=InputBox(“请输入一个整数”) Loop Print c+d End Sub 程序运行后，单击命令按钮，如果在输入对话框中依次输入1、2、3、4、5、6、7、8、 9和0，则输出结果是D.9

单项选择题通过变异操作,使遗传算法具有局部的随机搜索能力。对此,下列说法不正确的是( ) A、当产生一个可行解时,可以在该解的邻近解的集合中进行搜索,被称为局部搜索;该解的邻近解的集合是变化的,例如与该解有一位不同的邻近解、与该解有两位不同的邻近解,或者与该解有一个“位组合”不同的邻近解等; B、当产生一个可行解时,由于与该解的邻近解的集合可能很大,并不能穷举每一个邻近解,所以需要随机选择邻近解; C、当产生一个可行解时,通过某一位或几位的变异,便可产生该解相邻近的解。即相当于,以该解为中心,在与该解的邻近解的集合中随机选择出某个解; D、当产生的可行解接近最优解的邻域时,通过某一位或几位的变异,便可产生该解相邻近的解,此有助于使算法加速向最优解收敛; E、以上说法有不正确的;
