A group  about as at by for in of on with without    business people has opened a kind  about as at by for in of on with without    gym for robots. The group is headed  about as at by for in of on with without    Elon Musk, who is the boss  about as at by for in of on with without    the electric car company Tesla Motors and the space tourism company, SpaceX. Mr Musk also founded the online payments website PayPal. His latest project is called OpenAI Gym. It is a platform  about as at by for in of on with without    researchers and code writers to test their latest work. It is an open platform, which means people are free to test their ideas  about as at by for in of on with without    artificial intelligence (A.I.)  about as at by for in of on with without    it. In particular, researchers can test and share their algorithms  about as at by for in of on with without    A.I. Algorithms are special sets  about as at by for in of on with without    rules in a computer program that can solve problems and quickly deal  about as at by for in of on with without    large amounts of information. Mr Musk wrote  about as at by for in of on with without    the OpenAI Gym project and why his team decided to put it online  about as at by for in of on with without    free. He said: "Our goal is to advance digital intelligence in the way that is most likely to benefit humanity  about as at by for in of on with without    a whole, [ about as at by for in of on with without    the] need to generate financial return." The OpenAI Gym follows the idea  about as at by for in of on with without    giving rewards  about as at by for in of on with without    successful learning – similar to giving a dog a treat when it learns something new. This is called reinforcement learning. If an algorithm does well  about as at by for in of on with without    the gym, it gets a reward. If the algorithm fails, it gets no reward and it has to try something different. The aim  about as at by for in of on with without    the gym is to develop an algorithm that can multi-task - do many things  about as at by for in of on with without    the same time - rather than be good  about as at by for in of on with without    doing just one thing.
