Today we’re visualizing graph algorithms on Paris.
Then you’ll have to validate at least one problem.
Paris graph Jupyter notebook
- Question 0
- A drunkard is making a random walk in Paris. What does it look like?
You can visualize using matplotlib
plt.scatter with a different color
c='r' or Folium.
- Question 1
- Compare a shortest path between two points by walk and by car. Plot both paths.
When we are walking, we can take both sides of the street; and the cost is the length. When we are traveling by car, we have to respect the sides given in the dataset, and the cost is the duration.
- Question 2
- RATP is asking you to build metro lines that connect any two points of Paris. Cost of digging a line is proportional to its length. What should you do?
- Question 3
- We want to visit every station of Paris exactly once while walking as few as possible. Write an algorithm for this.
