How to Start a Saloon Business
Want to start a saloon business as a part-time or side business? Fashion-conscious and ordinary people are all very careful now to take care of their skin and make themselves beautiful and attractive. And the saloon is an important place to make yourself tidy. Saloons are no longer limited to just cutting hair and beard. Skincare massages and even beauty practices like beauty parlors can now be done in salons

A Handout in Graph Theory 11: Bellman Ford

An Algorithm for Finding Shortest Paths in Bellman-Ford Graphs. This algorithm takes a node as a source and finds the shortest path to all nodes from there. We learned Breadth First Search to do this at the very beginning. But since BFS does not work on weighted graphs, we next learned Dijkstra’s algorithm. Now let’s learn Bellman Ford because none of the previous algorithms work on graphs with edges of negative weights.

When we were studying Dijkstra we learned about relaxation. If you don’t remember or haven’t learned Dixtra, we do a little welding first. If you remember you can skip the next part and go directly here.

Edge Relaxation:

Suppose a graph has the distance/cost of each node from the source d[]

in the array. For example, d[3] means that a total distance of d[3] has to be crossed to reach node number 3 after crossing different edges from the source. If the distance is not known, then I will leave a value of infinity, that is, a very large value. And cost[u][v] contains u−v

Edge’s cost.

Suppose you go around different places and go from Farmgate to TSC in 10 minutes and again from Farmgate to Curzon Hall in 25 minutes. So with farmgate as source we can say:

  d[TSC] = 10, d[Curjon Hall] = 25

Now you can go to Curzon in 7 minutes from TSC.

  cost[tsc][cursion is] = 7

So instead of 25 minutes you can go to Karj Nahal in just 10 + 7 = 17 minutes. As you have seen:

  d[tsc]+cost[tsc][cost] < d[cost is]

So you can go to Curzon Hall through this new road and make d[Curzon Hall] = d[TSC] + cost[TSC][Curzon Hall]!!

That’s what the picture above says. We go from u to v if d[u]+cost[u][v] < d[v]. And update d[v] to make d[v]=d[u]+cost[u][v]. In the future, if I can go to Karjanhal by another road in less time, then I will compare and update that road like this. It goes something like this:

This is edge relaxation. Now we are ready to learn Bellman Ford.

Bellman Ford

In the following graph we want to find the shortest path from 1 to each node:

Initially d[1]=0

Reason 1 is the source. We put infinity in the rest because we don’t yet know the cost of the shortest path.

You’ve learned how to edge relax. Now the task is to relax all the edges at once, in any order. To ‘relax the graph’ once means to relax all the edges of the graph at once. I want to relax in the following order,

You can get the edges in any other order if you want. Now consider what we get in the d[] array once we relax the edges? We will get the cost of the shortest path from the source to another node using at most 1 edge. Update the values of d[] after relaxing in the above image. After doing this the image should look like below:

I could not update the cost of some nodes during edge relaxation because d[u]+cost[u][v] < d[v] did not satisfy the condition. After updating the rest of the edges d[]

I got the value of the array as shown in the above image. Now we know the shortest path from node 1 to all nodes using at most one edge!

Now relax once more to find out the cost of the shortest path to all nodes using maximum 2 edges! It can be done again in any order, but it is convenient when writing code to do it every time in the order it was first done.

Note that the shortest path from 1 to 6 has 3 edges (1->3, 3->4, 4->6) and the path length is 2+1+5=8. After only relaxing 2 times, we now have 8 in d[6], whereas we are now supposed to get the cost of the shortest path using at most 2 edges. It depends on the order in which you have edge relaxed. That’s why even though the shortest path to 5 is 10, d[5] still doesn’t get 10. If you ‘graph relax’ X times, you will definitely get the shortest path to each source node using at most X edges. You may or may not get the shortest path to each node using more than X edges after graph relaxation X times, depending on the order of the edges.

Now relax for the 3rd time:

This time only node number 5 will be updated.

Then every time we update, d[]

There will be no change in the array, we have found the shortest path from 1 to every node.

Now naturally the question will come that how many times to relax? If the graph has n nodes then at most n−1 to go from one node to another node

The edge must be used. That means a node can be updated at most n−1 times. So the relaxing loop must also run n−1

times However, as we have seen in the above graph, no node can be updated after 3 times, so there is no need to relax again.

Now run the Bellman-Ford algorithm on the following 3-node graph only, i.e. relax the entire graph as long as no node can be updated:

In a 3-node graph, the shortest path from the source to any node should take no more than 2 edges, and if you try to relax for the 3rd time, no node should be updated. But updating this graph:

This is because 1−>2−>3−>1 cycle total weight is negative (3+2–10=−5). So the shorter you cycle the shorter the shortest path. So if there is a negative cycle and there is a path from the source to that negative cycle then the shortest path to the source is undefined. If after relaxing the graph n−1 times we see that n

Even if the cost of a node is updated for the th time, it should be understood that we are in a negative cycle, it is not possible to find the shortest path.

Our sudocode would then look like this:

Print the path:

Paths can be printed here in the same way as paths are printed in BFS or Dxtra. previous[]

Take an array of names. previous[v]=u means at vth node you are from u. Initially the array will contain infinity. Make previous[v]=u while relaxing the u−>v edge. Now you are previous

You can extract the path of any node from the source by looking at the array.


At most n−1

Each time each edge has to be relaxed, the time complexity is O(n∗e).


Some issues to think about:

  You are given a graph that tells you the maximum x on the shortest path

  There may be an edge. Now how to find the shortest path? (UVA 11280)

  How to find the negative cycle part of any node in a graph? (Hints: Strongly Connected Components + Bellman Ford)

How to Start a Saloon Business
To start this business, you have to rent a shop in the market or market and decorate the shop suitable for the saloon. Then you have to buy the necessary equipment and cosmetics. After that, a skilled craftsman will have to be appointed to cut and save the hair.

In the salon, along with the adults, the children should also have a haircut. The value of cutting, saving, etc. of hair should be fixed and kept in the salon. Besides, customers who come to the service should always be treated well. This is how a saloon has to be operated.

Necessary equipment and cosmetics
To start a saloon business, cosmetics such as mirrors, combs, scissors, towels, hooves, blades, soap, shampoo, shaving cream, lotion, fitkiri, hair collars, tissues, etc. are needed as equipment.

Those who will be customers – boys and men of all classes are the main consumers of this business. Consumers will come to take the service for their own needs.
Qualification: No special qualification is required to start this business. However, skilled craftsmen must be employed. You have to sit down every month or week.

By starting a salon business, you can earn from $ 20,000 to $ 50,000 per month.
