Constructor: YSumUniquenessConstraint(int, IEnumerable<int>, int, int)

• Declared in: PuzzleSolvers.Exotic.YSumUniquenessConstraint

Declaration

public YSumUniquenessConstraint(
    int sum,
    IEnumerable<int> affectedCells,
    int minValue = 1,
    int maxValue = 9
)

Summary

Describes a “Y-sum” constraint: the first Y numbers must sum up to a specified total, where Y is the Xth digit and X is the first digit. This constraint implies a uniqueness constraint.

Parameters

int	sum	The total that the affected numbers must sum up to.
IEnumerable<int>	affectedCells	The set of cells affected by this constraint. This is usually a row or column in a grid, but it can be any subset of grid points.
int	minValue	The minimum value of numbers in the grid for this puzzle.
int	maxValue	The maximum value of numbers in the grid for this puzzle.

Remarks

Warning: This constraint is very memory-intensive. It is implemented as a CombinationsConstraint with all of the possible number combinations for the specified set of cells. Avoid using this on oversized puzzles.
