This is our (Stéphane Magnenat and Francesco Mondada) entry accepted in the AAAI-11 video competition.
This video presents a marXbot robot with a magnetic manipulator performing autonomous construction in an unknown environment with scarce resources, which requires understanding and reasoning about the environment.
At the beginning of the experiment, the robot knows neither the geometry nor the topology of the environment. It does not know where the resources are located. The robot does know that building a tower requires three resources, and that a remote resource can be fetched by building a bridge. In the video, the decision to build this specific bridge to fetch the remote resources was the robot's own one, done by reasoning using an HTN planner, whose source code is available at http://gitorious.org/planner9 .

Portfolio management is the art and science of making decisions about investment mix and policy, matching investments to objectives, asset allocation for individuals and institutions, and balancing risk against performance. Portfolio management is all about determining strengths, weaknesses, opportunities and threats in the choice of debt vs. equity, domestic vs. international, growth vs. safety, and many other trade-offs encountered in the attempt to maximize return at a given appetite for risk.

Portfolio Management Tips for Young Investors.
One of the reasons most often given for not investing is a lack of knowledge and understanding of the stock market. This objection can be overcome through self-education and step-by-step through the years because investors learn by investing. Classes in investing are also offered by a variety of sources, including city and state colleges, civic groups, and not-for-profit organizations, and there are numerous books aimed at the beginning investor.
Early Higher Risk Allocation.
An Exemplary Egg.
The idea is to select stocks across a broad spectrum of market categories. This is best achieved through an index fund. Aim to invest in conservative stocks with regular dividends, stocks with long-term growth potential, and a small percentage of stocks with better returns or higher risk potential.
Certain AAA-rated bonds are also good investments for the long term, either corporate or government. Long-term U.S. Treasury bonds, for example, are safe and pay a higher rate of return than short- and mid-term bonds.
Keep Costs to a Minimum.
