Learn about algorithms, their importance, and how they are used to solve problems effectively in this introductory video.

What are algorithms and why should you care? We'll start with an overview of algorithms and then discuss two games that you could use an algorithm to solve more efficiently - the number …

Binary search is an efficient algorithm for finding an item from a sorted list of items. It works by repeatedly dividing in half the portion of the list that could contain the item, until you've …

Here's the idea behind the algorithm that this program uses: move 1 square closer to the goal—the place the user clicked on—in each step. But what does "closer to the goal" mean? …

One way to come up with approximate answers to a problem is to use a heuristic, a technique that guides an algorithm to find good choices. When an algorithm uses a heuristic, it no longer …

Using recursion to determine whether a word is a palindrome

Sorting a list of items into ascending or descending order can help either a human or a computer find items on that list quickly, perhaps using an algorithm like binary search. JavaScript has a …

A machine learning algorithm that's trained on current arrest data learns to be biased against defendants based on their past crimes, since it doesn't have a way to realize which of those …
