Subject: Question about GLPK
Date: Thu, 15 May 2014 11:59:05 +0200
Hello,
I’m a dataminer consultant and I’m testing GLPK for one of our client.
I would know if it’s possible to use a combination of a “sum” and a
“min”.
For example, the kind of constraint that want to use is :
And I want to programming like that but it doesn’t work because we can’t
use a sum in the min function:
s.t. limit: sum{c in C} min (1 , sum{i in I,j in J, a in A}
x[c,j,i,a]) >= 25;
Is there a solution?
Thank you,
