Chess will never be solved, here's why

All Black has to do is resign, so the possibility obviously exists.

If you're asking if Black has a forced mate then it can be a matter of probability if the timeout rules, for example, are in force.

interesting. please show me..

are you being funny?

Not very.

He's never done this. do you have reading comprehension isseus?

" 1 e4 e5 2 Ba6? is a white loss, ultra-weakly solved."

objectively false.

a mathematical solution requires the game tree or formal proof.

you obviously dont have the game tree, so where's the proof?

tygxc why do you continue to cite definitions that you have no understanding of?

And shouldnt you take the fact that everyone else could understand what elroch was saying while you couldnt as a sign of your own incompetence? not understanding the arguments made by others is literally the first sign that you don't know what you are talking about.

Thanks for this observation (which resembles one by @tygxc where he justified his conclusion about the optimal result of chess by saying that was a definite thing with no uncertainty in it. But clearly his thinking was wrong - the fact that a theorem is definitely either true or false does not excuse lack of rigor in a proof).

I hope I can clarify this point by drawing attention to the Bayesian viewpoint. It can be proven that Bayesian probability theory is the only consistent way to quantiify BELIEF about propositions (given some very mild assumptions based on how beliefs need to behave). Not everyone will be familiar with this application of probability theory, which is separate to the more familiar one that has the much narrower scope of "repeatable random events")

In the case of the lottery ticket, viewed from the future, whether the ticket is a winner or not is a definite thing with no uncertainty. But in the past, whether it won was uncertain. The appropriate belief state in the past was one embodying the 1 in a quadrillion chance of winning.

Likewise, for the optimal value of chess, despite what people who inappropriately conflate strong confidence based on empirical evidence and inductive reasoning with certainty say, at the moment the appropriate belief state is an uncertain one. Exactly what probabilities you allocate to a black or white win is a matter of subjective modelling (just like the probability one would allocate to a given very large number being prime, for example), but the probabilities for all three results should be non-zero. With most of the probability on a draw, IMHO!

Likewise for the position 1. e4 e5 2. Ba6, until this position is solved. It may seem absurd to suggest that we don't even know that white is not winning - this is very unlikely - but my logical self demands that I allocate this possibility some tiny probability (for the specific reason that my logical self CANNOT deduce the opposite, and nothing can be truly certain without being deduced. Of course, no-one is ever going to have a problem ignoring really tiny probabilities - in a lifetime it is the difference between zero and tiny is unlikely to have any effect, but the philosophical difference is huge.

Intuitively, it may help to think in terms of log odds. The reason is that the log odds scale extends from -infinity to +infinity, with certain falsehood (0 on the probability scale) being minus infinity on the log odds scale and certain truth (1 on the probability scale) being plus infinity on the log odds scale. I feel this better indicates the very big difference between certainty and high confidence. Big numbers are not infinity!

AIs and neutral networks in general typically work with log odds as raw output (or something similar when there are more than 2 possibilities).

i didn’t say that white lose by force. just think of it for a moment. for you it should be a brief to recognize the subtle nuance. not sure about some others..

@Sillver1, I see now you asked the question that I have just tried to answer (whether rhetorical or not, I can't be sure!).

The thing which we express as a probability is our belief state. That is what Bayesian probability is about.

‘Thanks for this observation’

you welcome.

Note that Bayesian probability is maximally subjective in a sense. It does not prohibit someone from having a prior belief state which is certain. But according to the appropriate cross entropy error function, such a belief is infinitely expensive if it is wrong! So it is fair to say it is inappropriate/unwise to be certain without being able to justify the certainty.

it was an attempt to point llama in the right direction. now i can go back to waste my time on something more enjoyable.. lol

i can see why you say that, and objectivity speaking that’s ok.

LMFAO false on all levels.

all five had many famous proofs, and the four color theorem never had a faulty proof.

never did this. he simply claimed that you do not have rigorous proof of your assertion.

of course, tygxc, with your lack of math education, you could not tell the difference.

Geez, now you can't even come up with your own funny things to compare to...it's like your mind scrambles up everything other people say and then spits it back out in 2 weeks with you taking credit and claiming you said it before anyone else. I used crumpet because it makes a good analogy with your persona...British, pretending to be solid, but full of holes and hot air, softens when butter is added...easy to chew up and spit out.

A perfect example of how your logic about solving chess works. "Thus claimed the opposite" is not a workable leap.

Just stick Optimissed in his own version of A Beautiful Mind, then put an imaginary secret cartel off to the side whispering in his ear and stoking these delusions...the major plot hole is, Optimissed only imagines himself to be as smart as John Nash, so it all falls apart. Maybe if you retitle it A Mediocre Mind...
