优化了二个函数。减少了运算量,感觉速度有明显上升。当然,穷举 》4 阶以 魔方阵还是很慢的。

程序代码:

Private Sub Command1_Click()
Text1.Text = ""

MFJ = Val(Text2.Text)
If MFJ < 3 Then MFJ = 3

MFG = MFJ * MFJ

ReDim AA(MFG)
Dim i As Long
Dim j As Long

Dim js As Long

For i = 1 To MFG
    ReDim AA(i).Hw(MFG - i + 1)
    AA(i).Count = MFG - i + 1
    
    AA(1).Hw(i) = i                         '第一个元素的范围是全满
    AA(i).Index = 1                         '指针均先指向1
Next i
    AA(1).Count = MFG                       '第一个元素永远是满范围

    
    '第一个元素
    AA(1).Index = 1
    AA(1).Value = AA(1).Hw(AA(1).Index)

用公式算法填 魔方阵,仅完成奇数部分,偶数部分,4X 部分,不去弄了。直接百度一下,然后按算法写就是了。

程序代码:
Option Explicit

Dim AA() As Long
Dim MFJ As Long             '阶数
Dim MFG As Long             '总个数

Private Sub Command1_Click()

Text1.Text = ""

MFJ = Val(Text2.Text)
If MFJ < 3 Then MFJ = 3

Dim i As Long, j As Long
Dim X As Long, y As Long
Dim x1 As Long, y1 As Long
    MFG = MFJ * MFJ                 '总元素个数
    ReDim AA(MFJ, MFJ)                   '重定义数组

If MFJ Mod 2 = 1 Then                   '奇数魔方阵

    '魔方阵的排列规律(奇数阵):
    '⑴将1放在第一行中间一列?
    '⑵从2开始直到n×n止各数依次按下列规则存放:每一个数存放的行比前一个数的行数减1,列数加1。
    '⑶如果上一个数的行数为1,则下一个数的行数为n,列数加1。如果上一个数的列数的n时,下一个数的列数为1,行数减1。
    '⑷如果按上面的规则确定的位置上已有数,或上一个数是第一行第n列时,则把下一个数放在上一个数的下面。
    
    
    '填 1 部分
    X = 1                       '1行
    y = Int(MFJ / 2) + 1        '中间列
    AA(X, y) = 1                '给值
    For i = 2 To MFG            '从2开始
        x1 = X - 1              '第2条、3条规则始
        If x1 < 1 Then
            x1 = MFJ
        End If
        y1 = y + 1
        If y1 > MFJ Then
            y1 = 1
        End If                  '第2条、3条规则结束
        If AA(x1, y1) > 0 Then  '判断是否符合第4条规则
            x1 = X + 1          '计算第4条规则
            If x1 > MFJ Then
                x1 = 1
            End If
            y1 = y
       
        End If
            AA(x1, y1) = i      '给值
            X = x1              '当前位置
            y = y1
    Next i
    
End If
    
    Call 输出结果



'Label2.Caption = "结果总数:" & js

End Sub


Private Sub 输出结果()
Dim i As Long, j As Long
Dim s As String
Dim s2 As String
s = ""
For i = 1 To MFJ
    For j = 1 To MFJ
    Select Case Int(Log10(AA(i, j) + 1))
        Case 0
            s = s & "     " & AA(i, j)
        Case 1
            s = s & "    " & AA(i, j)
        Case 2
            s = s & "   " & AA(i, j)
        Case 3
            s = s & "  " & AA(i, j)
        Case Else
            s = s & " " & AA(i, j)
    End Select
   Next j
    s = s & vbCrLf
Next i

s = s & String(3 * MFJ, "-")

s2 = Text1.Text
If Len(s2) > 0 Then
    s2 = s2 & vbCrLf & s
Else
    s2 = s
End If

Text1.Text = s2

End Sub

   Log10 = Log(X) / Log(10#)
End Function
