Summary

Encapsulates a 9×9 Sudoku puzzle with Killer cages (sum + uniqueness constraints).

Constructors

KillerSudoku(string field, params int[] sums)
Constructs a Killer Sudoku with cages (regions) that each have a SumConstraint and a UniquenessConstraint.
KillerSudoku(string field, int[] sums, int minValue)

Instance methods

Puzzle
AddConstraint(Constraint constraint, ConsoleColor? foreground = null, ConsoleColor? background = null)
Adds the specified constraint to the Puzzle.Constraints list.
Puzzle
AddConstraints(params Constraint[] constraints)
Adds the specified constraints to the Puzzle.Constraints list. (see also remarks)
Puzzle
AddConstraints(IEnumerable<Constraint> constraints, bool avoidColors = false)
Adds the specified constraints to the Puzzle.Constraints list.
Puzzle
AddGivens(params ValueTuple<int, int>[] givens)
Adds a range of GivenConstraints from the specified array of tuples.
Puzzle
AddGivens(IEnumerable<ValueTuple<int, int>> givens, ConsoleColor? foreground = null, ConsoleColor? background = null)
Adds a range of GivenConstraints from the specified collection of tuples.
Puzzle
AddGivens(string givens, ConsoleColor? foreground = null, ConsoleColor? background = null)
Adds a range of GivenConstraints from the specified string representation.
Puzzle
AddGivens(int?[] givens, ConsoleColor? foreground = null, ConsoleColor? background = null)
Adds a range of GivenConstraints from the specified array representation.
Puzzle
AddKillerCage(int sum, IEnumerable<int> affectedCells, ConsoleColor? foreground = null, ConsoleColor? background = null)
Adds a cage (region) for a Killer Sudoku. This is just a SumConstraint and a UniquenessConstraint for the same region.
Puzzle
AddKillerCage(int sum, string affectedCells, int gridWidth = 9, ConsoleColor? foreground = null, ConsoleColor? background = null)
ConsoleColoredString
SolutionToConsole(int?[] solution, int width = 9)
Converts a Sudoku solution to a ConsoleColoredString that includes the coloring offered by some constraints.
ConsoleColoredString
SolutionToConsole(int[] solution, int width = 9)
IEnumerable<int[]>
Solve(SolverInstructions solverInstructions = null)
Returns a lazy sequence containing the solutions for this puzzle.
