Summary

Describes a “killer cage”: the numbers within the region must be unique and sum up to a specified total.

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

SumUniquenessConstraint(int sum, IEnumerable<int> affectedCells, int minValue = 1, int maxValue = 9)

Constructor.

Static methods

int[][]	GenerateCombinations(int minValue, int maxValue, int sum, int num, int[] forbiddenValues = null)	Generates all combinations of num unique values between minValue and maxValue that sum up to sum.
int	TranslateCoordinate(string str, int gridWidth = 9) Inherited from Constraint	Converts a convenient coordinate notation into a puzzle-grid index.
IEnumerable<int>	TranslateCoordinates(string str, int gridWidth = 9) Inherited from Constraint	Converts a convenient coordinate notation into puzzle-grid indices.

Instance methods

ConstraintResult	Process(SolverState state) Inherited from CombinationsConstraint Overrides: Constraint.Process(SolverState)	Override; see base.
string	ToString() Inherited from CombinationsConstraint Overrides: object.ToString()	Override.

Instance properties

int[]	AffectedCells Inherited from Constraint	The group of cells affected by this constraint, or null if it affects all of them.
bool	CanReevaluate Inherited from CombinationsConstraint Overrides: Constraint.CanReevaluate	Override; see base.
int?[][]	Combinations Inherited from CombinationsConstraint	The set of combinations allowed for the specified set of cells.
int?	NumCombinations Inherited from CombinationsConstraint Overrides: Constraint.NumCombinations	Override; see base.
int	Sum	The total that the cells must sum up to.
