Chapter 9: Searching Data Structures and Finding Shortest Paths

This chapter will discuss the searching techniques of graph, tree, and network data structures and practical applications of graph searches. We will introduce and analyze two popular algorithms for related problems: depth-first search (DFS) for graph searches and Dijkstra's algorithm for finding the shortest paths between vertices in networks. Both are introduced on small graphs to build intuitive understanding, and Python implementations are written that can scale up to real-world problems.

In this chapter, we will cover the following topics:

  • Searching graph and tree data structures
  • Depth-first search algorithm
  • The shortest path problem and variations of the problem
  • Finding shortest paths with brute force
  • Dijkstra's algorithm for finding shortest paths
  • Python implementation of Dijkstra's algorithm

By the end of this chapter, you will be able to explain the purpose...

Learning about data structures and algorithms gives you a better insight on how to solve common programming problems. Most of the problems faced everyday by programmers have been solved, tried, and tested. By knowing how these solutions work, you can ensure that you choose the right tool when you face these problems. This book teaches you tools that you can use to build efficient applications. It starts with an introduction to algorithms and big O notation, later explains bubble, merge, quicksort, and other popular programming patterns. You'll also learn about data structures such as binary trees, hash tables, and graphs. The book progresses to advanced concepts, such as algorithm design paradigms and graph theory. By the end of the book, you will know how to correctly implement common algorithms and data structures within your applications.
