 | | jessicafischerqueen: <El Phantom of the Opera> heh
Thanks! I am just figuring out the position in our game at the moment. I've been "working" on it today and tonight a bit.
just scratching the surface at the moment though.
Very good example at <The Center> of the <Raghbka> limitations. I'm wondering if the machine would not be short sighted on six move combos if the <hash brown tables> were ratched up to number 11? I was reading that the more calculating power you put in the <hash brown> tables, the more the computer looks before it starts pruning branches off the move tree. is it not true that they can be turned up so high that all of your hard drive is used? You see I don't even know what a <hash brown table> is exactly, although they are certainly a tasty breakfast item. I'm not sure how much I want to know even.

I've done some simple research and a calculation for a <full width> 8 ply deep search: After the 8th ply (Black's move) -- means 25,600,000,000 possible positions (nodes) need to have been analysed by the engine, which can not be done by a state of the art laptop, hence the "pruning" starts considerably earlier in the tree... I hope to post more on that this weekend.
It's not my fav subject either, but I did want to fix some major lacunas in my factual knowledge and understanding. Turns out I (we) were pretty much on the right track already, anyhow... |

| | jessicafischerqueen: <El Hash Tablephant> Good work!
I suggest we withold our next move in the game until we go through twenty five trillion possible positions, to be on the safe side. |

| Jan-15-09 | | achieve: I agree, just to be on the "safe side" ... hehe!
But seriously, that "petaflop/sec" <Roadrunner> Champ costs 100 million dollars, and is... hang on... <The interconnecting system occupies 6,000 square feet with 57 miles of fiber optics and weighs 500,000 pounds. Although made from commercial parts, the computer consists of 6,948 dual-core computer chips and 12,960 cell engines, and it has 80 terabytes of memory housed in 288 connected refrigerator-sized racks.The cost: $100 million.
Turek [vice president of IBM’s supercomputing programs] said the computer in a two-hour test on May 25 achieved a ”petaflop” speed of sustained performance, something no other computer had ever done. It did so again in several real applications involving classified nuclear weapons work this past weekend.> Read and weep. (Predicting) Nuclear warhead aging (hmmm, perhaps there is more behind this story) is its main application. Looks like Billionaire Chess promoter Joop van Oosterom times x is needed to get a Roadrunner that can search at 14 PLy full width within 3 minutes... That'll be fun.

And it takes 4 and a half days to boot up.

Stupid computers. They want to use it also to predict the weather for 2 weeks in advance... It's just a mammoth simulator instrument.

Just came back from my weekly glance at the <travesty page>. Check this out from the Big Cheese-- <Perhaps you missed it, but the forums have been suspended for the balance of this game. A lot of work goes into the setting up of the forums and almost no one was using them anymore.> No surprise to me.
It only takes one forum- the main page- to post <Rybka> lines. Why don't they just rename the game <Random Visitor's Rybka v. Arno Nickel's Rybka>? What a joke.

| | jessicafischerqueen: And this is even worse. Notice how this chess analyst from the <TRAVESTY PAGE> feels the need to apologize that he isn't a <chess computer> before he gives a "human" explanation of an aspect of the position. The worst part about this it that he feels the need to apologize for something <Rybka> can't do. <I'll give it a shot but I am no Rybka... 1. This was a move Rybka found at 28 ply
2. The fifth rank is a good place for that rook in this game, moving it to g5 maintains that placement. 3. It is a flexible, non commital move (relative to moving a pawn) 4. Puts pressure on White's g2 pawn
5. Clears the h5 square for the knight in some variations

Here is <Rybka's> version of this brave man's explanation: <0001110010101001010101010> More concise, surely? |

HAHAHAHA
Trouble is, Black's position is so computerized that is probably the best way of looking at it now anyway. |

Certainly. Especially (as you phrased it) for the to self-parody nearing chessplayer as computer nerd. Pity for all Kutz's work. Howard wrote something on it at my place. Whoopaaa - hope we'll have a good week end!

| | jessicafischerqueen: very, very good discussion of the <travesty> of Centaur chess at <The Euwe Center>... And also ideas about how Centaur chess can be used to learn about chess, as opposed to obeying <Rybka> like a stinking slave. Have you seen <Terminator III>? Who knew that it would come true so quickly...
And what the heck is a <petaflop>? I don't llke it.
Phones either.

| Jan-16-09 | | achieve: I really wanted to know some things myself, just to ease my mind and check my intuitions... Sharing them is just, well more than, a bonus. I'm not afraid to dive into these numbers... Another estimate I read yesterday was that the number of possible positions is more like 35^120 Completely impossible number to handle for dozens of decades to come... |
