Since itS early development in the
1950s, artificial intelligence (ai) has been studied
to mimic the function of human brains in solving
science and engineering problems. despite alternating bust and boom periods, ai has consistently progressed with a number of development
milestones such as evolutionary algorithms,
neural networks, and deep learning. For many
ai test applications, the game of Go has been
long considered one of the hardest problems and
the most difficult among all major board games
for ai to solve or mimic the way that the human
brain functions.
the game of Go, also called Weiqi or Baduk, is a strategic board game that originated in china more than 2,500
years ago and has been popular in east asian countries with
a growing interest in europe and north america, especially in
the academia of computing and mathematics. it is played by two
players alternatively placing black and white stones on a 19 × 19 grid
with the goal to surround more territory than the opponent. thus, it is
sometimes literally translated as the surrounding game (see Figure 1).
although its rules are simple, Go has enormous complexity at the scale
of 10170 in state space or 250150 in game tree while the complexity for
