“LEGO Mindstorms robots with a ZCS controller in a simulated physical world”

April 8th, 2010
The abstract of my thesis:
In this thesis, a Zeroth level Classifier System (ZCS) controller is compared to a hand-made controller (which features some simple rules to control the robot). The experiments are done in a world with continuous time and space. Their task is surveillance. The controllers control a LEGO Mindstorms robot with 4 wheels, a touch sensor, a pen device and a camera which can track the pen track. The pen track fades over time, and is used by the controllers to communicate indirectly.
The experiments are done in three worlds. Each experiment features three robots with controllers of one type (either ZCS or hand-made). The ZCS controller has been optimized using a meta-evolutionary algorithm, but this did not yield better results than the not-optimized ZCS controller. Overall, the ZCS controller did not perform as good as the hand-made controller.

Add generics (<>) highlighting to jEdit

I’ve got a svn account on Unfuddle. But bzr also works with ordinary ftp and ssh accounts, and thus I wanted to switch to bzr. But how can I move my files from my svn to bzr?

My laptop runs Ubuntu ‘Intrepid Ibex’ 8.10. Sometimes, my laptop does not switch off after pressing the power button or clicking the ‘shutdown’ option. The laptop makes an attempt to close all proceses, but after the Ubuntu splash screen, a blikking cursor remains instead of a dead laptop.
launchpad.net, I read a post from someone with the same problem and I solved it using his instructions:

Synchronize your Nokia N95 in Ubuntu using USB

November 18th, 2008

Synchronizing a Nokia phone with Windows is easy: download PC Suite and that’s all. However, PC Suite does not run on Linux at all (In my case that’s Ubuntu 8.10: Intrepid Ibex) and thus you do not have a tool to synchronize your contacts or calendar with your computer. Or is there?

Add POIs to Nokia Maps 2.0

October 29th, 2008

Nokia has been present on the GPS market for some time, and a half year ago the company launched their own Nokia Maps 2.0: it runs on Nokia mobile phones and, in contrary to other products, you pay for using the program – all maps are free.
If you start Nokia Maps 2.0, there is no option to import landmarks (favorites) into the program. However, I did succeed in loading the POIs!
