python ./main.py Use your mouse to select a cell, and use the numpad or number row to input a digit. For now, the game doesn't tell you whether or not you solved the puzzle, as it is mainly made to visualize the backtracking algorithm. To run the auto solver, hit ↵ Enter and...

The asynchronous backtracking algorithm (ABT) 算法 Asynchronous backtracking (ABT) 算法假设所有智能体(agent)都有各自的优先级(priority)。网络中每个智能体都知道自己的“上级”和“下级”都是哪些agent。 智能体知道他们自己的值,并且将这些值发送给自己的下一级智能体。所有的智能体都在等待消息,并回复消息。
