Re: [Help-glpk] optimizing a set of values

[Jeffrey Kantor]

From page 38 of the gmpl.pdf -- 

"As a rule the model description contains only one objective statement that

defines the objective function used in the problem instance. However, it is

allowed to declare arbitrary number of objectives, in which case the actual

objective function is the first objective encountered in the model description.

Other objectives are also included in the problem instance, but they do not

affect the objective function"

This is consistent with the behavior you've observed.

Hello everyone,

 

Could someone let me know if the optimization of a vector of value is possible with GLPK ?

In more details:

 

I have a set parameter:

X:=1..10;

And i would like to maximize the variable V[i] for all i belongs to X.

I defined the objective function as follow:

maximize fct{i in X}: V[i];

But it seems that the returned value for the objective function consider only V[1].

 

Is it possible to do this otherwise ?

 

Thank you

 

Esma
