GoThe game of Go

The game of Go originated in China more than 2,500 years ago.

Two players alternately place black and white stones with an aim of surrounding more territory than the opponent in a board of 19x19 grid lines.

The game is exponentially more complex than chess - the number of possible games is 10^761 in Go as opposed to Chess' estimated 10^120 possible games.

AlphaGoGoogle subsidiary DeepMind's AlphaGo program

Google owned DeepMind's AlphaGo is an artificial intelligence program developed in London to play the ancient Chinese board game Go.

AlphaGo displayed a marked improvement from all other existing Go-playing programs.

In 500 games against all other available Go programs, AlphaGo running on a single computer won all but one.

Running on multiple computers, AlphaGo won all 500 matches against other Go programs.

This scientific domain of inquiry has always been controversial due to its widespread implications. So much so, that these controversies had even affected funding and development programmes regarding AI.
