TryConstrain(IReadOnlyPuzzle, ExactCoverGraph)

Adds necessary IObjectives and links to the given graph in order to solve the given puzzle according to this constraint. The details here are implementation-specific.

Declaration

public bool TryConstrain(IReadOnlyPuzzle puzzle, ExactCoverGraph graph)

Parameters

Type	Name	Description
IReadOnlyPuzzle	puzzle	The puzzle to solve.
ExactCoverGraph	graph	The exact-cover graph to constrain.

Returns

Type	Description
System.Boolean	False if the constraint could not be satisfied by the given puzzle, else true.

Remarks

This should skip adding objectives that are already satisfied by the given puzzle. Instead, it should drop the relevant Possibilitys that are no longer possible.

Note: See ExactCoverGraph to understand how the graph works.
