hi
i have the following dvar variable

[b]tripRng=0..20[/b]
[b]dvar int tripSeq[tripRng] in Trips;  [/b]

how to write a constraint which will give an array (tripSeq) with at least 7 different elements from each other?

thank you

I would try something like that:


sum(i in Trips) minl(1, count(tripSeq, i)) >= 7;
