Google will put artificial intelligence to the ultimate test next month when AlphaGo takes on world champion Go player Lee Sedol in South Korea.

But you don't have to be in the region to watch the match. The five-game challenge will be livestreamed on YouTube between March 9 and 15, according to DeepMind founder Demis Hassabis.

Invented in China more than 2,500 years ago and enjoyed by more than 40 million people worldwide, Go requires players to place black or white stones on a board and capture the opponent's pieces or surround empty spaces to build territories.

Despite its apparent simplicity, the game features more possible moves than there are atoms in the universe, making it a tough competitor for traditional "brute force" artificial intelligence methods.

But Google's DeepMind AI division saw this as an "irresistible challenge," and started building what they called AlphaGo.

The program uses a state-of-the-art tree search with two deep neural networks—one to suggest intelligent moves, and another to evaluate each option. AlphaGo then chooses what it deemed the most successful maneuver.

When pitted against top artificial intelligence Go programs, Google's software won all but one of its 500 games. Even reigning three-time European Go champion Fan Hui was no match for the machine, which triumphed five games to zero, marking the first time a computer program beat a pro Go player.

"The most significant aspect of all this for us is that AlphaGo isn't just an 'expert' system built with hand-crafted rules, but instead uses general machine learning techniques to allow it to improve itself, just by watching and playing games," the DeepMind team said in a recent blog post.

The AI had better keep practicing, though, or Sedol may walk away with the $1 million match prize.

"I have heard that Google DeepMind's AI is surprisingly strong and getting stronger, but I am confident that I can win at least this time," Sedol said in a statement, published by VentureBeat.

The South Korean champ isn't the only one who's looking forward to the competition.

"It is a real privilege and honor to be playing the greatest Go player of the past decade, and a legend of the game," said Hassabis.
