Deep Fritz 13 Portable 90
Myong Killings
I guess it depends on how you will use it, and if your computer is able to make use of the program correctly. Deep Fritz allows your computer's multiple processors to compute separate lines simultaneously. If you have a quad core, it can compute lines 4 at a time. My PC is a dual core, so it isn't nearly as beneficial to me as it would be to you if you have a quad core. I don't have either, but have wanted Fritz 13 for a long time. I've waffled on buying it, but Arena is free, and comes with Rybka 2.2 and several other engines all totally free. The GUI is quite easy to understand, and free. Did I mention that it's free? Lol, I'm sure Deep Fritz would be awesome, though. If I had plenty of extra cash, I'd buy it.
I know Deep you have to pay for the deep part after 6 months and both adjust to your level of play but why did they put out two versions? Can anyone explain why they are both Fritz but one is put out ChessBase and the other by Viva Media?
I already have Fritz 13 but I am thinking of upgrading it to Deep Fritz 13, to take advantage of my new i7 quad-core processor. Does anyone know how you install Deep Fritz 13 over Fritz 13? Do you have to uninstall Fritz 13? Are there any problems in upgrading from Fritz 13 to Deep Fritz 13.
That's right. You need Fritz not for the chess engine (which, although good, it's far from being among the best), but for its functionality. You'd be better off installing and using Stockfish, Critter and Houdini 1.5 for you analysis in Fritz, and that's what I'm actually doing. Note that Critter is better in analysing tactical positions and Stockfish is better at more strategic situations.
BTW, starting from Fritz 14, it comes only in the Deep version (since single core processors is a thing of the past).
I can let anyone know about Deep Fritz 14, it's on it's way. Just ordered it on Black Friday (20%) off so I haven't tried it yet. Keep my link and ask me in a week or two and I'll do my best to update. I have never owned a chess program before so I'll have a long learning curve. BryPin
Arena is free as in beer but proprietary and SCID vs PC is free and open source.
When I used Arena I did find it a bit awkward to accomplish things, but I figured everything out pretty quickly. SCID, on the other hand, is extremely easy to use. Personally I've been using ChessX recently which I think is just yet another fork of SCID.
These programs are just as capable so it baffles me why people would spend so much money on software.
This paper discusses the creation of a genetic algorithm to locate and optimize interplanetary trajectories using gravity assist maneuvers to improve fuel efficiency of the mission. The algorithm is implemented on two cases: (i) a Centaur-class target close to the ecliptic plane and (ii) a Centaur-class target with a high inclination to the ecliptic plane. Cases for multiple numbers of flybys (up to three) are discussed and compared. It is shown that, for the targets considered here, a single flyby of Jupiter is the most efficient trajectory to either target with the conditions and limitations discussed in this paper. In this paper, we also iterate on possible reasons for certain results seen in the analysis and show how these previously observed behaviors could be present in any trajectory found. The parameters and methods used in the algorithm are explained and justified over multiple real-life interplanetary missions to provide deeper insights into the development choices.

Fritz Verzr, founder and one of the most important operator of experimental gerontology, was born 120 years ago at Budapest (Hungary) and passed away in 1979 at Basel (Switzerland) at the age of 93. This short paper, as well as the following one in this issue by Robert [Robert, L., 2006. Fritz Verzr was born 120 years ago: his contribution to experimental gerontology through the collagen research as assessed after half a century. Arch. Gerontol. Geriatr. 43, 13-43], intends to commemorate his human and scientific merits, which remained valid even after long decades after his death. The author of this paper was the last Hungarian pupil of Verzr; therefore, a personal touch of this commemoration could not be avoided and was not even wanted. Verzr was an exceptionally clever and realistic scientist and at the same time, a warm-hearted and honest man, who is remembered with deep respect and love.
