| Property: bool Toroidal
Declarationbool Toroidal SummaryIftrue , the constraint considers the grid to be toroidal, meaning that it wraps around the left/right
and top/bottom edges. Thus, in a Sudoku-sized grid, A1 would be a knight’s move away from B8 and H2. If
false , the knight’s move cannot extend beyond the bounds of the grid. |
