Re: An AI program that teaches itself

The problem is that, like most real problems, improving computer code 
has no simple one-dimensional measure of "better".  Go games are won or 
lost.

Even more interesting is how AlphaGo Zero got so smart. The older 
program AlphaGo had to start by analyzing hundreds of thousands of 
championship level games made by human players, but AlphaGo Zero 
started with nothing but the simple rules of GO and instructions to 
learn to get better. At first the program was terrible but day by day 
it got better and after 40 days of thinking about the problem 
became the best at it in the world. But of course after 40 days of 
constant self modification no human being can say how  AlphaGo Zero 
works.

It seems to me the next logical step would be to switch the program's 
interest from getting better at the game of GO to improving computer 
code, including its own. I wonder where that could lead.

An AI program that teaches itself

Google reports in the current issue of the journal Nature that it has a new
greatly improved Go program called  "AlphaGo Zero" that is now the most
powerful GO program in the world. And the program isn't good because
of brute force, it needs to make less than one tenth as many calculations
as the previous best GO program "AlphaGo" that defeated the world's top
human GO player in 2015  4 games out of 5; and yet AlphaGo Zero just
defeated AlphaGo in a 100 game tournament 100 games to zero.

Even more interesting is how AlphaGo Zero got so smart. The older program

level games made by human players, but AlphaGo Zero started with nothing
