Re: LCZero update
His problem with AlphaZero is that it dares to suggest that the current paradigm of chess engineering might not be the global optimum, which is an unforgivable affront to... something.

Re: LCZero update
One thing to remember - the training games are played with randomization: https://github.com/glinscott/leela-ches ... #L169-L194. Eg. even if the search picks a good move, we can cause it to randomly select another one. This is done to ensure we explore more possibilities and every now and then that random selection will be better than the search, and the network will hopefully learn something .Uri Blass wrote:I look at the games and I see a lot of stupid one ply blunder that lose material.Leo wrote:Its logical to try LCZero to see if it works. I am skeptical but not a pessimist.
I do not know what they do but if after many thousands of games it plays like that then I do not believe in it.
So, the training games are not a good representation of the real strength of the network.
That being said, it will still blunder right now. Let's see where we are in a few months .

Another thing I wanted to ask is, why doesnt it castle ?. Can anyone point me to a game where it actually castled ?

Re: LCZero update
I was thinking - once LCZero is trained to a higher level, is it possible to train the weights to make draws less interesting? e.g. score draws as 0.3 instead of 0.5 to make it play more aggressively for a win?

Re: LCZero update
If it positively effects the performance then one might try that. However, I would stick with the usual scoring system as they are many other things that need to be worked on (Especially promoting the program to get more ppl involved). Restarting the training right now, doesn't seem wise.Robert Pope wrote:I was thinking - once LCZero is trained to a higher level, is it possible to train the weights to make draws less interesting? e.g. score draws as 0.3 instead of 0.5 to make it play more aggressively for a win?

Re: LCZero update
It already plays very aggressively (if you go to http://lczero.org/stats you'll see that the draw rate during self-play is incredibly low), so I don't see a need to try and force more aggressiveness for now.

Re: LCZero update
draw rate is low only because it plays on a level of 3-years old kid.

Re: LCZero update
Exeperience shows that draw level is not so low at the lowest human level of children and you often get stalemates.Vizvezdenec wrote:draw rate is low only because it plays on a level of 3-years old kid.

Re: LCZero update
If you actually look at the network history (which I assume you didn't bother to do, since checking the facts seems to be beneath you), you will see that the draw rate has been decreasing as training progresses. A random mover draws against itself far more frequently than the current network does.
So no, it does not simply have a low draw rate because it plays "like a three-year-old child". Wonder what it will take before you people start to understand.
