In this talk, we discuss an integrated Belief-Desire-Intention (BDI)
modeling framework for human decision making and planning, whose
sub-modules are based on Bayesian belief network,
Decision-Field-Theory, and probabilistic depth first search
technique. A key novelty of the proposed model is its ability to
represent both the human decision-making and decision-planning
functions in a unified framework. In this talk, the proposed modeling
framework is demonstrated for human's evacuation behaviors under a
terrorist bomb attack situation. To mimic realistic human behaviors,
attributes of the BDI framework are reverse-engineered from the
human-in-the-loop experiments conducted in the Cave Automatic Virtual
Environment (CAVE) available at The University of Arizona. A crowd
simulation is then constructed, where individual human behaviors are
based on what was learned from the CAVE experiments. In this work,
the simulated environment and humans conforming to the proposed BDI
framework are implemented in AnyLogic agent-based simulation software, where
each human entity calls external Netica BBN software to perform its
perceptual processing function and Soar software to perform its
real-time planning and decision-execution functions. The constructed
crowd simulation is then used to test impact of several factors
(e.g. demographics of people, number of policemen, information sharing
via speakers) on evacuation performance (e.g. average evacuation time,
percentage of casualties). Finally, we discuss other emergency
evacuation applications (e.g. evacuation behaviors under fire in a
factory) and research extensions for the proposed BDI framework

The talk, based on a book of the same title (co-authored by
Greg Hoglund), exposes the inner workings of online game security
for all to see, drawing illustrations from MMORPGs such as World
of Warcraft to discuss:
- Why online games are a harbinger of software security
issues to come
- How millions of gamers have created billion dollar virtual
economies
- How game companies invade your privacy
- Why some gamers cheat
- Techniques for breaking online game security
- How to build a bot to play a game for you
- Methods for total conversion and advanced mods
But ultimately this talk is about security problems associated with
advanced massively distributed software. With hundreds of thousands
of interacting users, today's online games are a bellwether of modern
software yet to come. The kinds of attack and defense techniques I
describe are tomorrow's security techniques on display today.
