WebIn Java, Travelling Salesman Problem is a problem in which we need to find the shortest route that covers each city exactly once and returns to the starting point. Hamiltonian Cycle is another problem in Java that is mostly similar to Travelling Salesman Problem. The main difference between TSP and the Hamiltonian cycle is that in Hamiltonian ... WebQ 2. Explain Travelling Salesman Problem and solve it using backtracking. Ans: Traveling Salesman Problem (TSP) - Explanation With backtracking, it is solved by mehods: pruning: use best solution found so far to eliminate some choices . if smallest cost from current city to unvisited city results would result in a tour cost greater than best ...
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 ... WebMar 20, 2024 · The traveling salesman problem (TSP) has commanded much attention from mathematicians and computer scientists specifically because it is so easy to describe and so difficult to solve. The importance of the TSP is that it is representative of a larger class of problems known as combinatorial optimization problems.
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.

Using backtracking, you only have to look at around 15,000 branches. In summary, backtracking lets us look at every possible state in the tree, but in a smart way: it lets us cut off anything we don't want to consider.
