The A* algorithm is a really interesting one. It's conceptually quite simple if you approach it from the right angle, but most of the time I've seen it poorly explained, and as a consequence, people really struggling to "get it". My little contribution is a very accessible series of articles that derives A* almost from scratch, in a way that is really easy to understand: http://gabrielgambetta.com/path1.html http://gabrielgambetta.com/path1.html
