In the previous articles, we have presented graphs with BFS and DFS. The BFS is actually good to find the path with the fewest nodes. But if the path with the fewest nodes is actually the most expensive, then we…

Shortest route between points in a city – with Python and OpenStreetMap
After the article for introduction to Graphs in Python, I have decided to put the graph theory into practice and start looking for the shortest points between points in a city. Parts of the code are inspired from the book…
VBA – A* Search Algorithm with Excel
Ok, so some 10 years ago, I was having fun coding A* Search Algorithms in Excel in VitoshAcademy and this is what I had built back then: VBA – A* search algorithm with Excel – Really? VBA – A Search…
Python – Algorithm – Calculate Average distance with Dijkstra
In the current article I will try to solve a problem for calculation of average distance with Dijkstra, given in codeforces.com contest here in pdf. What is the problem like? We have n weighted graphs like this: For each given graph,…
Python Algorithms – Full Dijkstra is stunning again
Yesterday I have spent some hours, trying to resolve one problem for shortest paths. The problem was coming from HackBulgaria and was somehow similar to these two problems here: Get the shortest path in a weighted graph with Dijkstra Dijkstra for…

Python – Get the shortest path in a weighted graph – Dijkstra
Today, I will take a look at a problem, similar to the one here. In the article there, I produced a matrix, calculating the cheapest plane tickets between any two airports given. Today, the task is a little different. I would…
