Bound-consistent spread constraint: Application to load balancing in nurse-to-patient assignments
Given a vector of finite domain variables, the spread constraint aims at minimizing the sum of squares of these variables while constraining the sum of these to be equal to a given value. We improve the existing filtering for spread achieving a bound-consistent filtering without increasing the compl...
