Title: Google's AlphaGo beats human Go champion
Post by: SEO on March 10, 2016, 06:53:32 AM

Google's software (AlphaGo) beats human Go champion in first match

AI (Artificial intelligence) vs human. :) Google's software (named 'AlphaGo') beats a human go champion. (Source: CCTV /English news/)
 What's 'go'? 'Go' is an Asian game: 围棋 (wei-qi in Chinese), 囲碁 (igo in Japanese) and 바둑 (baduk in Korean). It's an abstract board game for 2 players, in which the aim is to surround more territory than the opponent. A photo from Shanghai, China shows a good example: (https://upload.wikimedia.org/wikipedia/commons/d/d8/Playing_weiqi_in_Shanghai.jpg)^{By Brian Jeffery Beggerly from S'pore, Singapore - IMG_2755, CC BY 2.0, https://commons.wikimedia.org/w/index.php?curid=3626565}

 It's a good game, but I can't play it. One of our students practice it seriously. :)
I think that more popular is the Chinese chess (xiangqi): https://en.wikipedia.org/wiki/Xiangqi. Many players all around. :)

What I found interesting is that the first article that mentioned the play off between AI and human champion mentioned the available possibilities of moves were more than there were stars in the observable universe!

Quote

Tromp and Farnebäck showed that on a 19×19 board, about 1.2% of board positions are legal (no stones without liberties exist on the board), which makes for 3³⁶¹×0.01196... = 2.08168199382... ×10¹⁷⁰ legal positions "of which we can expect all digits to be correct" (i.e. because the convergence is so fast).^[2] It has been estimated that the observable universe contains around 10⁸⁰ atoms, far fewer than the number of possible legal positions

After taking a look for a reference on that statement about stars, I found the above quote carrying the complication of possible moves even further.
