Summary

Describes a constraint in which a specific region of cells must sum up to a specified value.

Remarks

Technically this constraint is equivalent to a SumAlternativeConstraint with a single region.

Constructors

SumConstraint(int sum, IEnumerable<int> affectedCells)

Constructor.

Instance methods

ConstraintResult

Process(SolverState state) Overrides: Constraint.Process(SolverState)

Override; see base.

Static methods

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 properties

int[]	AffectedCells Hides Constraint.AffectedCells	The region of cells that must have the sum specified by SumConstraint.Sum.
bool	CanReevaluate Overrides: Constraint.CanReevaluate	Override; see base.
int?	NumCombinations Inherited from Constraint Virtual	Indicates an approximate number of possible combinations of digits this constraint can still accommodate. This will help the solver prioritize cells when multiple cells have the same number of combinations individually.
int	Sum	The desired sum.
