As suggested by our friend Zafer, this puzzle is in tribute to Georg Filser, the author of numerous great optimizations on LMD web site, devotee and master of filomino, who passed away this July.
On 21th of july I've learned that Georg Filser (aka geophil) had passed away from the
site Logic Masters Deutschland e.V. We haven't met personally but we have wrote each other
via Logic Masters forum site. I felt very sad when I've heard his passing Then towards the end of
july I told Jovan my idea about an optimizer dedicated to Georg and now here it is. I want to thank
Jovan realizing such an idea very quickly There were some nominees for the puzzle type and fillomino
was one of them. In june 2007 there was a fillomino optimizer published on LM site. Bernhard Seckinger
(aka Berni) mentioned that the idea for that optimizer and also the puzzle itself came from Georg.
So I think this one fits good here. I hope that there will be more puzzlers dealing with this nice task
till deadline which is on 18th of september. I know there exists lots of optimization addict good puzzlers.
I hope that they want to give a try in this one to honour Georg. Rest in peace Georg..
