Adversarial Reasoning: Computational Approaches to Reading the Opponent's Mind [Format Kindle]

"Adversarial Reasoning" is a powerful work and relevant for folks who are not computer oriented.

Coming from a liberal arts background (masters in poli-sci, BA in classical humanities), things like sigma notations and multiple Greek letters in a formula make me break out in a cold sweat and the shakes. Despite this disadvantage, the qualitative parts of each chapter were of great relevance to anyone involved in predictive analysis of n-player games (like geo-politics). Each chapter started with a clear and well articulated presentation of the material before going into the maths and computer applications of the concepts. It is this presentation that I read, before having to go for a lie-down when I saw all the formulae.

The book was laid out logically, with a handy little matrix to show the appropriate chapter for a given sub-topic up front. The first section was a discussion of the opponent and infering and identifying the opponent's intent. The second section was a discussion of deception. The third section was split between the impact of imperfect information and strategizing. Deception (building on the discussions of opponent's intent) was both the best developed concept, and probably the one most directly applicable by the non-computer person. Imperfect information, however, may be the most important discussion in the book as this is the situation most disturbing to real world actors.

The closest thing to a criticism is just a vague perception that the authors might be a little naive about the ruthlessness of real world actors. This may be an artifact of the academic language. Also, a closer examination of situations of asymmetric utility and the impact of this situation on all actors in game play would be valuable to real world applications.

Over all, a great work. This work re-written in purely qualitative terms for poli-sci and military folks (n.b. history is the most common major among Army officers) would be a valuble addition to the education of future political and military leaders.

For folks from liberal arts backgrounds - don't let the numbers cow you, there is a lot of value in the first pages of each chapter.

I have used this book to do a literature review on the topic for a wargame proposal. It has the most complete collection of state-of-the-art computational approaches to adversarial reasoning. Each chapter is carefully introduced with a few words to distinguish its approach from other chapters. Adversarial reasoning is a subdomain of AI that covers opponent modeling, deception reasoning and imperfect information games because of the inherent covert nature of the adversary. Some of the computational approaches illustrated include Bayesian nets, plan recognition, swarm intelligence, game theory, linquistic geometry, and approximating algorithms to scale up to large state space.

Traditional thinking about adversaries has addressed easily observable and quantifiable issues, such as what? how many? who? The undiscovered country is a place where other, perhgaps more relevant questions are answered: when? why? how likely? under what conditions? It is a place where, perhaps, one can makes reasonable stabs at "what is the adversary likely to do next?"

For anyone interested in going beyond the exercise of counting and analyzing things (airplanes, missiles, bullets, etc), this book is an essential addition. Why? Because it shows new applications of maturing fields of science to the task of UNDERSTANDING THE ENEMY.

The only weakness, and a minor one at that, is that the book, though new, does not address some of the state-of-the-art analytical tools now becoming available. But, perhaps these will be covered in follow-on books. They should be.
