Unfortunately, sometimes, we can develop real problems with our nails. One such example...In order to solve the problem using branch n bound, we use a level order. First, we will observe in which order, the nodes are generated. While creating the node, we will calculate the cost of the node simultaneously. If we find the cost of any node greater than the upper bound, we will remove that node.There are different applications in problems with a lot of nodes.

When the cost function satisfies the triangle inequality, we may design an approximate algorithm for the Travelling Salesman Problem that returns a tour whose cost is never more than twice the cost of an optimal tour. The idea is to use Minimum Spanning Tree (MST).
In Chapter 15 we introduced the Traveling Salesman Problem (TSP) and showed that it is NP -hard (Theorem 15.42). The TSP is perhaps the best-studied NP -hard combinatorial optimization problem, and there are many techniques which have been applied.
