Not long ago to do arithmetic modelling of the operation, to use the lingoAnd still have to re-provision the dynamic plan using lingoSo on Baidu found under how to use C + + deployment of lingo, the final result found to be a pitSo I got stuck in it and got two or three cows to figure out that there was a day in the house that didn't sleep ... To bucketHowever, it is clear, but also took a lot of detours, so to write down a little experience, summed u
We sometimes encounter heavy, repetitive work when using lingo, manual operation is obviously time consuming, and the @for function in lingo can only do some simple loops, which requires us to apply the script file to simplify these repetitive work. The English part below is an example from the Official Handbook, which summarizes the 2 points I find useful:1. script file type:. LTF However, the script file
The first step: Enter the target condition and the constraint condition. Each line is separated by semicolons. Then click the Solve button on the toolbar or the Solve submenu under the Lingo menu.Step Two: Check the results in the report.By default, lingo does not perform sensitivity analysis.Need to be configured in lingo to generate a sensitivity analysis repor
Assign values using verbose syntax
The logical operators in lingo use the single equal sign "= ".
Set Param To Value
Put Value Into Param
Verbose syntax to assign values more clearly.
Case-insensitive
Because case-insensitive is case-insensitive, note the comparison of strings.
Put"A" = ""

Case-sensitive
Lingo is not sensitive in most cases. Only one case is that the propert

3. maximum short circuit problem
Given N point Pi to form a set {Pi}, the distance from any point Pi in the set to another point Pj is represented by Cij. if Pi to Pj is not connected by ARC, cij = positive infinity, Cii = 0, specify an endpoint PN, and the shortest route from Pi to PN is required. Here we use dynamic planning.
And
