- Execute traversals and create graphs within a binary search tree structure

- Describe strongly connected components in graphs

Syllabus

WEEK 1

Binary Search Trees and Algorithms on Trees

In this module, you will learn about binary search trees and basic algorithms on binary search trees. We will also become familiar with the problem of balancing in binary search trees and study some solutions for balanced binary search trees such as Red-Black Trees.

WEEK 2

Basics of Graphs and Graphs Traversals

In this module, you will learn about graphs and various basic algorithms on graphs such as depth first/breadth first traversals, finding strongly connected components, and topological sorting.

WEEK 3

Union-Find Data Structures and Spanning Tree Algorithms

Union Find Data-structure with rank compression.

Spanning trees and properties of spanning trees. Prim’s algorithm for finding minimal spanning trees. Kruskal’s algorithm for finding minimal spanning trees.

WEEK 4

Shortest Path Algorithms

In this module, you will learn about:

Shortest Path Problem: Basics. Bellman-Ford Algorithm for single source shortest path. Dijkstra’s algorithm. Algorithms for all-pairs shortest path problem (Floyd-Warshall Algorithm)
