Summary

Describes an “X-sum” constraint: the first X numbers must sum up to a specified total, where X is the first of those digits. This constraint implies a uniqueness constraint.

Remarks

Warning: This constraint is very memory-intensive. It is implemented as a CombinationsConstraint with all of the possible number combinations for the specified set of cells. Avoid using this on oversized puzzles.

Constructors
