Re: [Help-glpk] maximum function

[Heinrich Schuchardt]

Hello Haroune,

 

the example below shows how to use the iterated form of the max and min functions.

 

set T := { 1 .. 10 };
param p{t in T} := sin(t);
display p;
printf "The maximum value of p[t] is %f\n", max{t in T} p[t];
printf "The corresponding t is %d\n", min{t in T : p[t] == max{u in T} p[u]} t;

Best regards

Betreff: [Help-glpk] maximum function

Hello everyone!

 

I need your help please. Is it possible to get the maximum of a variable only in one of her dimension? 

For example : I have the variable X[i,j,t] and I want to define something like that (after the optimisation) :

 

param Xmax {i in A, j in B} := max {X[i,j,t]}.

 

The problem is I don't know how and where to define "t in H"?

 

Thank you so much for your help :-)
