[rules-users] [optaplanner] Nurse rostering questions

1) So for example when using toy1.xml there is 140 shifts/assigments. This means each nurse(11 of them) will get about 10-15 assignments. (= DayOfWeekCover/cover/shift/preferred is 2) But what if I want to make sure in contract MinNumAssignments = 20 is met? DayOfWeekCover/Cover/shift would need to have minimum/maximum instead of preferred? 2) So I solve/make shifts for february using nurserostering. Then I want to do march. a) How to load old data? (Load feb solution and then advance 30 days?) b) What if my march data has employee/contract changes? Thanks, Karri
