The AI Summit features panels and lectures from top game AI programmers in the industry. Organized as a collective effort by the AI Game Programmers Guild, this event promises to give you an inside look at key architectures and issues within successful commercial games, as well as let you eavesdrop on conversations, debates, and rants on how game AI can move forward. This summit is targeted toward the intermediate to advanced programmer who wants deeper insight into the world of game AI, however anyone who is interested in what AI can offer next generation games will find invaluable insights and lessons from the speakers.

JPS+: Over 100x Faster than A*
Steve Rabin(DigiPen Institute of Technology)
It has been said that "pathfinding is a solved problem." Just because something is "solved" doesn't mean it can't be improved especially with regards to execution time. Normally, a speed gain of 10x or 100x over a traditional algorithm is unheard of. Recently, a method has been devised that is capable of doing just that to A*. In 2011, Harabor and Grastien introduced Jump Point Search (JPS) that achieves up to a 10x speed improvement over A* on uniform cost grids. In the last year, an additional 10x speed improvement to JPS, called JPS+ was independently developed by Steve Rabin as well as Harabor and Grastien. This improved algorithm is over 100x faster than A* on maps with open areas and over 2x faster than A* on worst-case maps. This incredible speed-up is due to pre-computation, eliminating the recursion in JPS and focusing only on touching select relevant nodes during the search.
Getting off the NavMesh: Navigating in Fully 3D Environments
Dan Brewer (Digital Extremes)
Space is big. Space is sparse - often with nothing to collide with. But what if your space also has groups of dense, complex geometry that the AI needs to navigate? NavMesh is the popular navigation representation for most games and it does a really good job for agents who move along the ground. However, it doesn't really work for agents who fly in any direction in 3D space. In developing the ArchWing space battles for Warframe, full 3D flight navigation and avoidance was required to function in a mix of sparse asteroid fields and the tight, complex confines of wrecked capital ship debris. This talk will cover the challenges faced in avoidance and navigation in 3D.
