3.7.25. Balanced assignment

A constraint to obtain a balanced assignment over a set of domain variables. Given a set of domain variables ${x_{1}, x_{2}, ..., x_{n}}$ , some classical balance criteria reported in [SchausDevilleDupont07a] are:

The maximum value, i.e., the maximum value over $x_{i}$ $(i \in [1, n])$ can be modelled with a $𝚖𝚊𝚡𝚒𝚖𝚞𝚖$ constraint.
The maximum deviation, i.e., the maximum value over $x_{i} - \frac{\sum_{j \in [1, n]} x_{j}}{n}$ $(i \in [1, n])$ .
The total deviation, i.e., $\sum_{i \in [1, n]} |x_{i} - \frac{\sum_{j \in [1, n]} x_{j}}{n}|$ can be modelled with a $𝚍𝚎𝚟𝚒𝚊𝚝𝚒𝚘𝚗$ constraint [SchausDevilleDupontRegin07], [SchausDevilleDupont07].
The total quadratic deviation, i.e, $\sum_{i \in [1, n]} {(x_{i} - \frac{\sum_{j \in [1, n]} x_{j}}{n})}^{2}$ can be modelled with a $𝚜𝚙𝚛𝚎𝚊𝚍$ constraint [PesantRegin05], [SchausDevilleDupontRegin06].
