Question

我是朱莉娅的新手并且正在尝试使用JuMP来解决NLP，下面是代码

Sub test22()

Dim num_of_row As Long
    Dim num_of_column As Long
    Dim i As Long, j As Long
    Dim template As Object
    Dim t As Object
    Dim name As String


    num_of_column = 20

    num_of_row = ActiveSheet.Cells(Rows.Count, "A").End(xlUp).Row - 1

    With CreateObject("word.application") ' late binding
        .Visible = False

        For i = 1 To num_of_row
            Set template = .documents.Open("D:\zzz LINH TINH\02. Test VBA\01. LRAMP\Template_KHQLMT.docx")
            Set t = template.Content
            For j = 1 To num_of_column
                t.Find.Execute _
                    FindText:=ActiveSheet.Cells(1, j).Value, _
                    ReplaceWith:=ActiveSheet.Cells(i + 1, j).Value, _
                    Replace:=wdReplaceAll
            Next
            template.SaveAs Filename:=ThisWorkbook.Path & Application.PathSeparator & i & "-KHQLMT " & ".docx"
        Next
        .Quit
    End With
    Set t = Nothing
    Set template = Nothing
End Sub

从代码中可以看出，每当求解器调用我的目标函数时，我会尝试计时并注意一些事情，下面是输出的一部分：

m = JuMP.Model(solver=Ipopt.IpoptSolver(max_iter=50,tol=1e-6))

function lkhf(x1,x2,x3,x4,x5,x6,x7,x8)
x = [x1,x2,x3,x4,x5,x6,x7,x8]
@time ll = loglikelihood(x,pdpoeFacSim,intercept, pdpoeFacMean, pdpoeFacInitial, pdpoeTarget, pdVar, poeVar,corPDPOE,resRnd)
return ll
end

JuMP.register(m, :lkhf, 8, lkhf, autodiff=true)

@nlobjective(m, Min, lkhf(x1,x2,x3,x4,x5,x6,x7,x8))

我不太明白为什么调用相同的目标函数导致gc时间明显不同。

请您就如何加快我的代码提供一些建议？
