    Delayed-Attached Dynamic Obstacles and Graph Optimizations in PathEngine

    The most common — and arguably most important — trick for optimizing search algorithms is reducing the size of the graph. If you can search a small one, why not do that? For pathfinding, this has lead to many techniques for better triangulating navigation meshes, reducing the number of nodes without compromising path quality or validity.

    Capture The Flag AI Competition: Results and Source Release

    During three months, starting mid-November 2012 and ending mid-February 2013, AiGameDev.com ran an AI Competition called Capture The Flag. We had rather ambitious goals for CTF, designing it to be more practical than academic competitions and more relevant than hobbyist contests. In the end, after many long hours of work by the many competitors and the organization team, it not only fulfilled our expectations but easily drove forward the current state-of-the-art in the field.

    How To Architect Your AI: Case Studies from Indie Games

    The best way to learn is from real examples! In this review, you'll hear about four different work-in-progress indie games, and in each case the AI hasn't been developed (much) yet. You'll learn how to approach the design, what factors to consider, as well as how to architect the system and lay out the implementation plan. By going through this process for iOS games, web-games and PC games, you'll be able to apply this to your own games too.
