Hello,

How can I create an object   f  var ofile = new IloOplOutputFile("Resultat.txt"); ; and call the object on my post process each time the model will be solved , my purpose is to create an object  " ofile "  one time  and call it, at each time my model will be solved and display the results in a file, I don't wanna do this on the main bloc  because I have a lot of parameters.

my model is an iterative one so it solves for different data and I am trying to output at  each time the results .

At this time it returns me only the last the iteration because at each time I am calling the postprocess it's creats a new file and crush the last results ...  

Another solution would be to copy the result that display Cplex/Opl  on its script box directly on my file , but i dont know how to do it with the language of Cplex/OPL .. 

Regards thanks ! 

Hi,

do not hesitate to use the append parameter:

IloOplOutputFile(path, append)

 

 

Parameters:

path - Optional: The path of the file to open.

append - Optional: If true, sets the stream position at the end of the file.
