This course will teach you the most important graph algorithms, covering both theory and implementations in C++.

Graph algorithms are the core of many real-world applications of computer science,  such as automotive navigation or routing in computer networks. They’re also a common subject in coding interviews at top-tier tech companies.
 
In this course, we’ll learn about the basic concepts of graph theory and how to represent graphs as data structures in code. We’ll study essential graph algorithms such as depth-first search or Dijkstra's algorithm to traverse graphs and find shortest paths. Finally, we’ll learn to solve more complex optimization problems on graphs, such as matching and network flow problems.

The second option to represent graph edges in code is the adjacency list. 

## Adjacency list

In this data structure, we store a list of each node’s neighbors. 

Let’s look at our example graph again. We use the same integer encoding of nodes that we did for the adjacency matrix.
