Hi,
1. I am writing now a magic square program in math prog.I have a problem with
formulating a constraint, that all the values in the square must be different.
...
/* variable x[i,j] */
/* x[i,j] value maximal n^2 */
var x{1..n, 1..n}, integer, >=1, <=n*n;
...
/* all diff */
s.t. ?????
...
I would be very grateful, if you could support me somehow.
greetings
