Case Study

To study path finding and the multi-threading problem, we will take the case of an autonomous rover that has to go from point A to point B with several obstacles on its path that it cannot cross. The following image represents the region on which the rover must evolve. It must go from point A (top left), to point B (bottom right). To visualize the places where the rover can or cannot pass, we have divided the map in 900 zones, and we have indicated to the rover if it can pass or not (image on the right).

There are a very large number of different paradigms, but the two best known are declarative programming and imperative programming. Some languages support only one paradigm, such as Haskell for functional programming. On the other hand, others may support more than one, such as Python or C++


In 2015, a one-way war broke out in France against VTC taxis (from French, Passenger Vehicles with Driver). They are invaders by the name of Uber, Lyft, Private Driver or Le Cab. At the origin of this anger is the development of the VTC and the unfair competition it represents according to taxis.

At the time the subject was different, they were mainly protesting against Uber POP, a service that connects customers with private individuals, which has since been banned. …
