![]() Go is hell to learn, but then so is chess, when the geeks cackle. And, fortunately, even us 28 kyu idiots can see the beginnings of unimagineable depths that provides this game's eternal fascination. Really, Go at the level GNU Go provides is not much more difficult than tic tac toe, once you learn to fire off more than one Kleenex deep layer of neurons. Go software is notoriously inept and provides the current "next big challenge" in AI research, but GNU Go is a great way to learn the basics. Sente's Goban is a virtual board which does a great many things, chief among them creating self-documenting Go games (Goban uses SGF files), watching or playing games on the major internet Go servers, replaying famous (and infamous) games of better players (or oneself), AND, LAST BUT NOT LEAST allowing you to humiliate yourself by playing against GNU Go 3.4 (or 3.6 if you download the latest) - which plays at the level of any 12-year old Japanese kid who's played for a few years. "Goban" is the Japanese word for the board on which one plays Go, and prices for these border on the ridiculous (primarily because Gaia does not grow 700 year old plum-yew trees fast enough to meet demand). (I assume the clock only works for network play?) And a little documentation would have been dearly appreciated for these more obscure features.īut it's free, so those are only observations, not complaints! For the price, this is a super-sweet little program which will let you enjoy a game against the computer (until you are about 10 kyu or so, at which point you ought to be able to kick Gnu Go 3.7's butt regularly) and give you access to view all those downloadable professional game files, and your own online game SGFs, with ease. (Attempting to use them at all is one of the few things that glitches the program up!) There are some features-such as using a timer-which apparently can't be activated at all. It would be nice if the SGF editing features were easier to use. ![]() SGF files with alternate paths and on-the-board notations don't work quite so well. ![]() Goban is fabulously easy to use as a game, or as a bare-bones SGF viewer. I have not attempted to download 3.9 and use it as an alternate player, to be fair, but my attempts to do the same with other Go game engines have all failed. It comes with Gnu Go 3.7 built in, but Gnu Go is now up to 3.9. The only reason I have not given it a full 5 stars is that it could use some updating and minor feature adds/fixes. I have only used it to play against the computer, as I use KGS's client software when playing on the server. As no decrease in mean individual weight with increasing water depth within either group could be observed, the change in meio:macrofauna ratios along the OMEX-transect merely reflects a change in taxonomic (functional) composition, rather than a change in size.I've been using this program for quite a while, almost daily, and have been very happy with it. Within the macrofauna a decrease in the abundance of filter- and surface deposit-feeders relative to the subsurface deposit-feeders with increasing water depth was observed, which may be related to a change in food input. Thus, large nematodes became relatively more important with increasing water depth. At the deepest station ∼20% of the macrofaunal fraction were nematodes, at the shallowest station only ∼2%. Within the macrofaunal fraction (>0.5 mm) a linear increase in the ratio between nematodes and macrofauna sensu stricto with depth was found. Run in Ubuntu Run in Fedora Run in Windows Sim Run in MACOS Sim. Macrofauna biomass was high at ∼1000 m, due to the high mean individual weight of the macrofauna, whereas meiofauna biomass and mean individual weight were low at this depth. This is the command goban that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator. At this depth macrofauna biomass was ∼55 times higher than meiofauna biomass, whereas at ∼4500 m macrofauna biomass was only about three times higher. The ratio in biomass between meio- and macrofauna showed a dip at ∼1000 m. ![]() This change in ratio was due to a significant decrease in macrofauna densities with increasing water depth, whereas the meiofauna densities stayed more or less at the same level. At the continental shelf meiofauna densities were ∼50 times higher than macrofauna densities, whereas in the abyss meiofauna densities were more than 1000 times higher. A linear increase in the ratio between meio- and macrofauna densities with increasing water depth was found. Meio- and macrofauna density and biomass were estimated at the OMEX-transect across the continental slope of the Goban Spur at water depths ranging from 208 to 4460 m in the north-east Atlantic. ![]()
