The asymmetric traveling salesman problem appears in various applications, such as vehicle routing problems, mixed Chinese postman problems, and scheduling problems with sequence dependent setups. Although there exist several heuristic procedures and branch and bound algorithms for it, the problem is still a difficult combinatorial optimization problem.
A branch and bound solution to the travelling salesman problem. To find the best path, the program traverses a tree that it creates as it goes. It uses a lower bound cost algorithm to prune paths who couldn't possibly be lower than the current best path. To initialize the best cost, a greedy solution is found.

For many other problems, greedy algorithms fail to produce the optimal solution, and may even produce the unique worst possible solution. One example is the traveling salesman problem mentioned above: for each number of cities, there is an assignment of distances between the cities for which the nearest-neighbor heuristic produces the unique worst possible tour.
