WebWe assume that every two cities are connected. Such problems are called Traveling-salesman problem (TSP). We can model the cities as a complete graph of n vertices, where each vertex represents a city. It can be shown that TSP is NPC. If we assume the cost function c satisfies the triangle inequality, then we can use the following approximate ... 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.
