Knight's tour

The Knight's tour is a famous chess puzzle in which the goal is to knight all the squares on the board so that you can only step on each square once. The knight moves to L, according to the rules of knight in chess. There are multiple chessboard options to choose from. After a few moves, you can use the "advise" option, where a genetic algorithm advises the move that leads to the best result in a given situation. But to make it less simple, it deliberately conceals whether the problem still has a solution.
