Summary

Describes a constraint in a number placement puzzle in which cells that are at specific relative placements from one another cannot contain the same value.

Constructors

AntiChessConstraint(int gridWidth, int gridHeight, int[] affectedValues = null, IEnumerable<int> enforcedCells = null)

Constructor.

Instance methods

ConstraintResult

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

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 Inherited from Constraint	The group of cells affected by this constraint, or null if it affects all of them.
int[]	AffectedValues	Optionally specifies a limited set of values that are affected by the constraint.
bool	CanReevaluate Inherited from Constraint Virtual	By default, a constraint is only evaluated once for every digit placed in the grid, but not when another constraint merely rules out a possibility. Derived types can override this and return true to indicate to the solver that the constraint should be reevaluated (meaning: have Constraint.Process(SolverState) called on it again) when another constraint rules out a value in one of the affected cells of this constraint.
int[]	EnforcedCells	Optionally specifies a limited set of cells on which the constraint is enforced. (see also remarks)
int	GridHeight	The height of the grid.
int	GridWidth	The width of the grid.
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.
