2 things.
first, Go is much more complex than chess. it took 20 years after deep blue to get the same level for AlphaGo.
second, a massive number of permutations doesnt necessarily mean that something cant be solved. checkers had 10 ^20 and was still solved. of course, chess is much much more complex, but the big number alone should dissuade us.
Your premise assumes that the efforts put into beating the world champs for Chess and Go were the same. This is not the case. Solving Chess was much better PR for IBM than solving Go would have been, so a lot more resources were brought to bear.
In terms of actually solving, IIRC Go has more positions...but evaluating Go positions should take less CPU horsepower than evaluating Chess positions.
btw, deep mind cost 400 million, while deep blue cost 100 million, although inflation might put deep blue over
its also funny how you still refuse to concede your original claim, that Go as a whole is less complex than chess.
Link it. No such claim was made.
