WebIn order to calculate the costs, you just need to sum up all the edge costs. For example for the route 3 -> 1 -> 2 -> 4 -> 5 -> 3, this yields. (3,1) => 3 (1,2) => 20 (2,4) => 4 (4,5) => 3 (5,3) => 7 ------------ sum 37. So, essentially you have to generate a first sample route and calculate its cost. As soon as you did this, you know that the ...

"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. " - Tsp problem using backtracking
