Summary

Describes a constraint in which a specific region of cells must sum up to the value in another cell. In a variant Sudoku, this is often represented as an arrow coming out of a circle, and hence, the variant is known as “Arrow Sudoku”.

Constructors

IndirectSumConstraint(int sumCell, IEnumerable<int> region)

Constructor.

Instance methods

ConstraintResult

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

Refer to the documentation for Constraint.Process.

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 Inherited from Constraint	The group of cells affected by this constraint, or null if it affects all of them.
bool	CanReevaluate Overrides: Constraint.CanReevaluate	Refer to the documentation for Constraint.CanReevaluate.
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[]	Region	The set of cells that must sum up to the value in IndirectSumConstraint.SumCell.
int	SumCell	The cell that must contain the desired sum.
