What makes the graph data structure very interesting and powerful is the large number of algorithms that can be run on graphs to extract insights. Common graph algorithms include traversing a graph and computing the shortest path between nodes. Implementing these algorithms is a great way to learn how graphs are explored and optimized. In this course, learn how graphs can be traversed by studying both depth-first and breadth-first graph traversal and discover how they can be implemented using a stack and a queue respectively. Next, explore how to compute the shortest path in an unweighted graph. And finally, use Dijkstra's algorithm to compute the shortest path in a weighted graph. Upon completion of this course, you will be able to implement optimal algorithms on graphs.
