Summary

Describes a constraint as used in Neighbor Sum Sudoku by Timwi (https://logic-masters.de/Raetselportal/Raetsel/zeigen.php?id=0005NV): Each number outside the grid gives the sum of all orthogonal neighbors of one cell in the corresponding row or column. Where multiple numbers are given, the sums must be in the same order as the clues.

Remarks

This is implemented as a CombinationsConstraint, which may make it very memory-intensive on oversized puzzles.

Constructors

NeighborSumConstraint(bool isCol, int rowCol, int[] clue, IEnumerable<UniquenessConstraint> furtherRestrictions = null, int gridWidth = 9, int gridHeight = 9, int minValue = 1, int maxValue = 9)

Constructor.

Instance methods

ConstraintResult	Process(SolverState state) Inherited from CombinationsConstraint Overrides: Constraint.Process(SolverState)	Refer to the documentation for Constraint.Process.
string	ToString() Inherited from CombinationsConstraint Overrides: object.ToString()	Override.

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 Inherited from CombinationsConstraint Overrides: Constraint.CanReevaluate	Refer to the documentation for Constraint.CanReevaluate.
int[]	Clue	Specifies the set of neighbor sums. Currently only 1 or 2 numbers are supported.
int?[][]	Combinations Inherited from CombinationsConstraint	The set of combinations allowed for the specified set of cells.
bool	IsCol	Specifies whether the constraint applies to a column (true) or row (false).
int?	NumCombinations Inherited from CombinationsConstraint Overrides: Constraint.NumCombinations	Refer to the documentation for Constraint.NumCombinations.
int	RowCol	Specifies the affected row or column (depending on NeighborSumConstraint.IsCol).
