which I liked to read, but I had to be subscribed to the journal that I am not from home (the University must be subscribed (true)). I prefer free science publication that the way it is going on.

Post those-busy-days era: Chaos control and Co-evolution

At last, I finished that bulk of reporting stuff that I was engaged in during last week. I must have written a technical report about Chaos Control and a paper on Evolutionary Robotics. These heavy works –with becoming near deadlines and too little time to do- was too stressful for me. Fortunately, I did them!

The first one that is written in Persian (Farsi) is a literature survey on different methods of chaos control. I have been fascinated about chaos for a long time (perhaps from the time I was 12. Yes?! What is the problem?!), but I could not find any possibility to do some real scientific research or at least readings. Despite a short not-too-academic research that I did in the first year of BSEE, I have found a chance to do a real one when I entered graduate school and begin my MS study (The first one was about using a chaos signal in order to solve some optimization problem. After that, I did two chaos control ones too).
Thus, this rather good literature survery was a very pleasant experience for me. In spite of those readings, I am not a chaos specialist anyway! 😀

The second one, which is entitled Behavior Evolution/Hierarchy Learning in a Behavior-based System using Reinforcement Learning and Co-evolutionary Mechanism, was a result of some experiences on evolutionary robotics. You may know that I believe in the evolutionary mechanism (be natural or artificial), though many think that it is just an idiot (with IQ = 0.0001) given enough time to try every cases. Nevertheless, I got some good results mixing co-evolution and learning which was fascinating. I mainly did this research in order to satisfy the requirement of getting a mark for Dr.Lucas’ Biocomputing course, but that was only an ignition. Anyway, Dr.Nili and Dr.Araabi told me not to submit this paper to any place before submitting some other papers before.

Chaos Control’s Seminar: The Last Part

My last part of Chaos Control seminar presentation trilogoy was presented yesterday. It was mostly dedicated to Bifurcation control which I was not professional at. Anyway, now I do know more than 99.99% of people (even more)!! 😀 This is the good part of it.
But something strange happened yesterday. oops!

Bifurcation surfing!

I’m busy with some readings mostly about Bifurcation. I’ll write about the papers and … that I read later, but it is worthy to mention some useful (or interesting) links that I encountered during my research. It may be useful later.

Chaos @ Maryland (you cannot find any paper here, but you can find every kind of chaos research!!)

Fredholm Alternative Theorem (It appears in one of bifurcation papers that I read.)

Implicit Function Theorem

Dynamical System Theory (Seems to be a book, but I haven’t looked at it. I was searching for Center Manifold Theorem that I found it).

Invariant Subspaces (I was looking for Popov-Belevitch-Hautus cont./obs. and I found this pdf. It is a good one).

Bifurcation (seems to be a good introductory one!)
