Moves: 0 |
This is a much simpler method than the Warnsdorff heuristic although based on
the same underlying principle that outer squares should be visited first.
The 8x8 grid, fashioned by James Weatherley in July 2004, is used to
decide which of the legal moves should be employed. The method is (1) Click on any square to begin . (2) Select move with lowest value. (3) If more than one choice select the rightmost cell if the tour commenced in the left half of the board else select the leftmost cell. The grid was first applied to a computer program by Geoff Wearmouth although it works just as well as a manual method and requires no trial and error. The strategy is determined at the outset and does not require any forward searching nor does it result in any backtracking. |
