title: Find the path with minimum cost between multiple nodes
body: <p>Can you please tell me what is the name of algorithm or serie of algorithms for the next configuration ?</p>
  
  <p>We have several clients ... We know the distance(cost) between each client ... And we know the start point.</p>
  
  <p>I need to find the optimal route for the delivery boy which must leave from the start point and he must pass 1 time at each client.</p>
  
  <p>Thank you</p>
