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,
