Kanada's Research Topics http://www.kanadas.com/research-topics-e/ en Copyright 2008 Sat, 31 Mar 2007 09:00:57 +0900 http://www.sixapart.com/movabletype/ http://blogs.law.harvard.edu/tech/rss Computation with randomized order Recently, computation methods with randomness are widely studied. Evolutionary computation including genetic algorithms and genetic programming are examples of such methods. Computation using simulated annealing, such as Bolzmann Machine, and methods for increasing efficiency using randomization in classical algorithms are also studied. The randomized computation models I previous studied, i.e., Chemical Computation Model (CCM) and randomized cellular automata (RACA), also used randomized computation.

There was so-called analog computer, but now it has become old fashioned. Nowadays, the word "computer" certainly means a digital computer. However, human senses are inherently analog, so I think computers should come close to analog senses for the sake of ease of use. It means that combination or fusion of good points of digital and analog is required. Although analog computers were dead, neural networks that replaced analog computers (?!) had some good points of analog things. Since I was stimulated by them, I thought of fusion of digital and analog very frequently.

It is time consuming to solve the N queens problem (See the description below), as same as other constraint-satisfaction problems. Therefore, many methods are deviced to solve it faster. In my research, I often used this problem as an example too.

Relatively light topics on one research theme are described in the general blog. I also made a Japanese version of this blog. By the way, the research themes in my company are described, but I write them as a research scientist and my company has no concern to these descriptions. ]]> http://www.kanadas.com/research-topics-e/2006/10/purpose_of_this_blog.html http://www.kanadas.com/research-topics-e/2006/10/purpose_of_this_blog.html Mon, 16 Oct 2006 23:09:02 +0900 My lifework I have studied CCM (Chemical Computation Model) for emergent computation, axis-specified search, voiscape (a virtual "sound room" based communication medium), and so on. There are common "themes" among the above three researches. They are "fusion of digital and analog" and "fusion of symbols and subsymbols".
