Summary

Describes a constraint in which a specific region of cells must have a specified product (multiplication).

Constructors

ProductConstraint(int product, 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 product specified by ProductConstraint.Product.
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?	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	Product	The desired product.
