This is a Travelling Salesman Problem (TSP) exercise, where the salesman needs to visit all the cities (A, B, C, D, E, F, G, H) and return to the starting city A, minimizing the total cost, which is the sum of the weights (distances) between the cities.

### Step-by-Step Approach to Solve the TSP:

1. **Cities Involved:** A, B, C, D, E, F, G, H.
2. **Distances (Costs) between Cities:** The numbers along the edges of the graph represent the costs.
   - For example:
     - Distance from A to B is 5.
     - Distance from B to D is 4.
     - Distance from G to H is 2, etc.

3. **Objective:** Find the route that visits each city once and returns to city A with the minimum total distance.

### Solving Method:
This is usually solved using algorithms such as:
- **Brute-force:** Trying all possible routes and selecting the one with the minimum cost (not efficient for large graphs).
- **Greedy Approach:** Selecting the nearest city at each step.
- **Dynamic Programming (Held-Karp algorithm)** or **Approximation algorithms** for faster computation in large graphs.

I'll now find a possible minimum route for this graph using a heuristic approach.

Let me calculate the approximate shortest route for this graph.

It seems like I can’t do more advanced data analysis right now. Please try again later.

In the meantime, you can attempt solving the Travelling Salesman Problem manually by considering different routes, adding up the distances, and choosing the one with the lowest total cost. Here are the steps:

1. Pick a starting point, say A.
2. Try different paths visiting each city once and returning to A.
3. Calculate the total distance for each path.
4. Select the path with the smallest total distance.

Would you like more tips on solving such optimization problems or further guidance? Here are some relative questions:

1. What algorithm could help solve the Travelling Salesman Problem efficiently?
2. How does the brute-force method compare with dynamic programming for TSP?
3. What are some real-world applications of the Travelling Salesman Problem?
4. Can approximation algorithms always guarantee an optimal solution for TSP?
5. What impact does the number of cities have on the computational difficulty of solving TSP?

**Tip:** In graph problems, breaking down the steps and trying smaller sets can make large problems easier to handle.

A salesman starts from the place A, should visit all the cities B, C, D, E, F, G, H and return to the origin city A. What is the route providing the minimum cost, and what is the cost?

This problem involves determining the optimal route with minimum cost for a salesman starting at city A, visiting cities B, C, D, E, F, G, and H, and returning to city A. The task uses concepts from Graph Theory and Optimization to minimize the total travel distance.
