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。智能体每次更改自己的值后,都把自己的新值发送给自己...
Thus, recursion is used in this approach. This approach is used to solve problems that have multiple solutions. If you want an optimal solution, you must go for dynamic programming. State Space Tree A space state tree is a tree representing all the possible states (solution or nonsolution) ...

In some cases, it is observed that its time complexity is factorial (0(N!)). Types of Backtracking ProblemThe backtracking algorithm is applied to some specific types of problems. They are as follows −Decision problem − It is used to find a feasible solution of the problem. ...
In this project, the backtracking algorithm is utilized to solve the Sudoku puzzle. Backtracking algorithm is a general-purpose algorithm for finding all (or some) solutions to certain computational problems, notably CSPs. This algorithm incrementally constructs solution candidates and discards a ...
