Classes

StandardHeuristic

Provides the standard UniqueIn* heuristics.

UniqueInBoxHeuristic

Checks for any squares that are the unique provider of a given possible value within a box. Sets the possible values for those squares to just their unique value.

For example, if a box had three unset squares with possible values: A: [1, 2], B: [1, 2], and C: [1, 2, 3], then this would set C's possible values to [3].

UniqueInColumnHeuristic

Checks for any squares that are the unique provider of a given possible value within a column. Sets the possible values for those squares to just their unique value.

UniqueInRowHeuristic

Checks for any squares that are the unique provider of a given possible value within a row. Sets the possible values for those squares to just their unique value.

UniqueInXHelper

IHeuristic

Performs some logical trickery to reduce the number of possible values for a square. Unlike an IRule, this depends on the current possible values in the puzzle, not just the currently set values.
