Never play games with a bot (機器人)—it will find a way to cheat if it can.A team from OpenAI,an artificial intelligence lab in San Francisco co-founded by Elon Musk,has developed artificially intelligent bots that taught themselves to cooperate by playing hide-and-seek.The bots also learned how to use basic tools and that disobeying the laws of physics can help to win.
In April,2019,a team of bots known as the OpenAI Five beat the human world champions at the team-based video game Dota 2.The hide-and-seek bots use similar principles to learn but the simpler game allows for more inventive play.
Bowen Baker at OpenAI and his colleagues wanted to see if the team-based dynamics of the OpenAl Five could be used to generate skills that could one day be useful to humans.The researchers set their bots loose in a simulated(模擬的)environment filled with fixed walls and movable boxes and left them to play team games of hide-and-seek millions of times.The bots each had their own view of the world and couldn't communicate with each other directly.At first,the hiders simply ran away.However,they soon worked out that they could find objects in the environment to hide themselves from view.For example,they learned that boxes could be used to block doorways and build simple hiding places.The seekers learned that they could move a ramp(斜坡)around and use it to climb over walls.The bots then discovered that being a team player was the quickest way to win.
The hiders also learned to
sabotage the other team,such as hiding the ramp before hiding themselves so that the other team can't make use of the ramp. "Once one team learns a new strategy,it creates this pressure for the other team to adapt," says Baker.
Such tricks show that AIs are able to find solutions that humans miss,says Baker. "Maybe they'll even be able to solve problems that humans don't yet know how to." However,there's still a long way to go from online hide-and-seek to real problem-solving.
