Question
In the context of this exercise, what are some other applications of directed graphs?
Answer
One example of a directed graph is for modeling a university curriculum. Each vertex can represent a course, and the edges going from the vertices can represent that the course is a prerequisite for the courses they are pointing to. Directed graphs can also be used for modeling natural occurrences such as water flow or wind patterns. They are also applied to technologies such as cryptocurrencies or compilers.
