Yes, I know that before coding it's good to have detailed plan (Due to
moving GSoC application deadline I will have more time to think of it :) )

I know that DRC is one of the most important things which I should take into
consideration...
I mean, that if the algorithm doesn't find move fulfilling DRC, it will be
better when it doesn't do anything.
After quite long time of thinking on this subject I made up my mind that maybe
physics methods are quite good, mainly because they determine simple goals.
Unfortunately, I have no good idea for efficient implementation of this. I
mean, that in my mind there are mostly approximate computations, which after
disturbing give satisfactory (stable) result through repeated iterations.
However,I don't know if it's a good idea...
