You've heard the term algorithm at some point in your programming journey, but how, exactly, are you supposed to turn an arcane series of steps into a solution for a problem that doesn't even look like the intended purpose?  How do we combine algorithms to conquer tasks neither could handle alone?

In this installment from How to Train Your Scrappy Programmer, we will explore various algorithms that can help solve hard problems, like:

  • Graph data structures and their algorithms
  • Pathfinding with Breadth-first Search 
  • Topological sorts
  • Polygon inclusion
  • Flood fills
  • And more!

We will discuss when and how to use them and why they excel at what they do.  We will dive into the world of algorithms to create dynamic solutions that not only work well together to solve a difficult problem, but create fun animations in the process. 

By the end of this interactive guide, you will have practiced finding and adapting multiple algorithms to turn seemingly insurmountable problems into fun and solvable puzzles.

Who Is This For?

This lesson is intended for any programmer who has heard rumors of the great power known as "algorithms" and is ready to peek behind the curtain. This guide has light references to some topics covered in previous guides. It is assumed that the reader will be comfortable with the use of Kino inputs, Stream iterators, Enum.into/3, and sets.

Expert level knowledge is not required. The free sample includes a code test that will help you decide if you are ready for this content. For those who aren't, links to free guides are included to help get you up to speed.

* This product requires a Livebook installation. There's a free desktop app for macOS and Windows.

A free sample is available that includes simple installation instructions, the table of contents, an introduction, one complete guide, a conclusion, and the occasional joke or two. Almost all code samples in the guide are written in the Elixir programming language, but know that this is an interactive environment where you can run, edit, and rerun all the code you see inline and view the results live. You are strongly encouraged to explore this sample to see if this content is right for you.
