how not to make themost common trading mistakes. If you are tired of reading how-tobooks, this is perfect for you. I highly recommend this book to alltraders. Everyone will learn something about themselves by readingthis book."—Kathy Lien, author, Day Trading the Currency Market,and Chief Strategist, www.dailyfx.com"Adventures of a Currency Trader is a must read foranyone who has ever traded or is thinking about trading in theForex markets. Rob Booker has a unique way of taking years ofmarket knowledge and transforming it into an educational andentertaining experience. It has quickly become a cult classic in mytrading library!"—H. Jack Bouroudjian, Principal, Brewer Investment Group"Brilliant! Rob's humor and humanity shine through in thisparable about trading and life. Filled with wisdom and wit, it's anexhilarating rollercoaster ride through the peaks and valleys ofthe learning curve, with many valuable lessons learned along theway."—Ed Ponsi, President, FXEducator.com"Rob's fable of everyman 'Harry Banes' is destined to become atrading classic. This is both the missing piece and the foundationthat comes before the strategies and methodologies. The search forthe Holy Grail begins and ends in the heart and mind. The journeyis authentic and real and if you're willing to take it with Rob,you will be rewarded in the end. Seldom has psychology and wisdombeen so entertaining!"—Raghee Horner, trader and author of Forex Trading forMaximum Profit and Days of Forex Trading"In a series of insightful and entertaining vignettes, RobBooker teaches both the novice and the experienced trader some hardwon truths about the currency market. It's a must read book writtenby a guy who survived the trenches and went on to prosper in thebiggest and most competitive financial market in the world."—Boris Schlossberg, Senior Currency Strategist, Forex CapitalMarkets LLC, and author of Technical Analysis of the CurrencyMarke

Filtered Fictitious Play for Perturbed Observation Potential Games and Decentralised POMDPs
No full textPotential games and decentralised partially observable MDPs (Dec–POMDPs) are two commonly used models of multi–agent interaction, for static optimisation and sequential decision-making settings, respectively. In this paper we introduce filtered fictitious play for solving repeated potential games in which each player’s observations of others’ actions are perturbed by random noise, and use this algorithm to construct an online learning method for solving Dec–POMDPs. Specifically, we prove that noise in observations prevents standard fictitious play from converging to Nash equilibrium in potential games, which also makes fictitious play impractical for solving Dec–POMDPs. To combat this, we derive filtered fictitious play, and provide conditions under which it converges to a Nash equilibrium in potential games with noisy observations. We then use filtered fictitious play to construct a solver for Dec–POMDPs, and demonstrate our new algorithm’s performance in a box pushing problem. Our results show that we consistently outperform the state-of-the-art Dec-POMDP solver by an average of 100% across the range of noise in the observation function
Learning in unknown reward games: application to sensor networks
No full textThis paper demonstrates a decentralised method for optimisation using game-theoretic multi-agent techniques, applied to a sensor network management problem. Our first major contribution is to show how the marginal contribution utility design is used to construct a unknown-reward potential game formulation of the problem. This formulation exploits the sparse structure of sensor networkproblems, and allows us to apply a bound to the price of anarchy of the Nash equilibria of theinduced game. Furthermore, since the game is a potential game, solutions can be found using multiagentlearning techniques. The techniques we derive use Q-learning to estimate an agent’s rewards,while an action adaptation process responds to an agent’s opponents’ behaviour. However, there aremany different algorithmic configurations that could be used to solve these games. Thus, our secondmajor contribution is an extensive evaluation of several action adaptation processes. Specifically,we compare six algorithms across a variety of parameter settings to ascertain the quality of thesolutions they produce, their speed of convergence, and their robustness to pre-specified parameterchoices. Our results show that they each perform similarly across a wide range of parameters.There is, however, a significant effect from moving to a learning policy with sampling probabilitiesthat go to zero too quickly for rewards to be accurately estimated
Decentralised Coordination of Unmanned Aerial Vehicles for Target Search using the Max-Sum Algorithm
No full textThis paper considers the coordination of a team of Unmanned Aerial Vehicles (UAVs) that are deployed to search for a moving target within a continuous space. We present an online and decentralised coordination mechanism, based on the max-sum algorithm, to address this problem. In doing so, we introduce a novel coordination technique to the field of robotic search, and we extend the max-sum algorithm beyond the much simpler coordination problems to which it has been applied to date. Within a simulation environment, we benchmarked our max-sum algorithm against three other existing approaches for coordinating UAVs. The results showed that coordination with the max sum algorithm out-performed a best response algorithm, which represents the state of the art in the coordination of UAVs for search, by up to 26%. The results further showed that the max-sum algorithm out-performed an implicitly coordinated approach, where the coordination arises from the agents making decisions based on a common belief, by up to 34% and finally a non-coordinated approach by up to 68%
Developing multiagent systems: the Gaia Methodology
No full textSystems composed of interacting autonomous agents offer a promising software engineering approach for developing applications in complex domains. However, this multiagent system paradigm introduces a number of new abstractions and design/development issues when compared with more traditional approaches to software development. Accordingly, new analysis and design methodologies, as well as new tools, are needed to effectively engineer such systems. Against this background, the contribution of this paper is twofold. First, we synthesize and clarify the key abstractions of agent-based computing as they pertain to agent-oriented software engineering. In particular, we argue that a multiagent system can naturally be viewed and architected as a computational organization, and we identify the appropriate organizational abstractions that are central to the analysis and design of such systems. Second, we detail and extend the Gaia methodology for the analysis and design of multiagent systems. Gaia exploits the aforementioned organizational abstractions to provide clear guidelines for the analysis and design of complex and open software systems. Two representative case studies are introduced to exemplify Gaia’s concepts and to show its use and effectiveness in different types of multiagent system
Rob and Bert in Tokyo
No full textThis essay is steeped in contradiction: it is as much an attempt at mourning, coping, and letting go as it is an exercise in remembrance, rediscovery, and reconnection. One of the many areas of international legal scholarship where Rob Cryer left his mark is his oeuvre on the International Military Tribunal for the Far East (IMTFE). To pay tribute to, and get re-acquainted with, Rob-the-person, I re-read his 2010 article on the ‘dignified dissenter’ in Tokyo, Dutch Judge Bert Röling. In that article, Rob uses the memoranda and the opinion of Bert-the-judge to assess his conceptual and legal contributions to the IMTFE judgment. They also serve him as a vehicle to get a better grasp of the author behind the text and the values and dilemmas that shaped Röling’s positions on the IMTFE bench. What more can we learn and understand about Rob Cryer while ‘reading Rob reading Bert’? What aspects of Röling’s legacy did he choose to foreground, and what qualities did he appreciate most? How did Rob treat his character when shedding light on the more contentious elements of Röling’s work? Even if this essay fails in its therapeutic purpose, it might still add a few mosaic pieces to the collective construction of Rob’s portrait in this volume
