This is my second post. I'm trying to study the nurse rostering examples. There is a way to avoid same shift in two consecutive day?

Are you trying to avoid shifts for the same nurse in two consecutive days? If yes, that would not be the same shift. There would be 2 shifts, assigned to the same nurse, with consecutive dates. You can write a constraint that penalizes it. – Eszter Oct 09 '20 at 12:25

Avoiding same shift type in 2 consecutive days goes like this:your "when" clause should be true when there are 2 ShiftAssignments of the same nurse,same shift type with your second ShiftAssignment having ShiftDatedayindex = ShiftDateDayIndex of first Assignment +1; ShiftAssignment(...$ShiftType1:shiftType,day1:shiftDateDayIndex,...) ShiftAssignment(...$ShiftType2:shiftType,$ShiftType1==$ShiftType2,day2:shiftDateDayIndex,day2==day1+1...)
