WebA backtracking algorithm is a problem-solving algorithm that uses a brute force approach for finding the desired output. The Brute force approach tries out all the possible solutions and chooses the desired/best solutions. The term backtracking suggests that if the current solution is not suitable, then backtrack and try other solutions.

WebThe state space tree shows all the possibilities. Backtracking and branch n bound both use the state space tree, but their approach to solve the problem is different. Branch n bound is a better approach than backtracking as it is more efficient. In order to solve the problem using branch n bound, we use a level order. WebWe assume that every two cities are connected. Such problems are called Traveling-salesman problem (TSP).
