量化合约系统开发（技术详解）丨量化合约系统开发（源码demo）

　　Artificial intelligence(AI)refers to the ability of computer systems to perform tasks similar to human intelligence.It is a complex technology,which constantly adjusts and improves its own algorithm by inputting a large amount of data into the algorithm for learning,so as to continuously optimize its performance.

　　AI can be divided into two categories:weak AI and strong AI.Weak AI(also known as narrow AI)refers to AI systems that can only show human intelligence in specific task areas.For example,voice recognition system,auto drive system,etc.Strong artificial intelligence(also known as generalized artificial intelligence)refers to an artificial intelligence system that can display human-like intelligence in various task fields like humans.

　　notice Convert Tokens to ETH.

　　dev User specifies exact input and minimum output.

　　param tokens_sold Amount of Tokens sold.tokens_sold为要支付的代币数量

　　param min_eth Minimum ETH purchased.min_eth为要购买的ETH的最小值

　　param deadline Time after which this transaction can no longer be executed.

　　return Amount of ETH bought.返回最终购买到的ETH数量

　　#函数功能：指定输入的代币数量，根据代币数量兑换ETH并发送给消息调用者

　　notice Convert Tokens to ETH and transfers ETH to recipient.

　　dev User specifies exact input and minimum output.

　　param tokens_sold Amount of Tokens sold.

　　param min_eth Minimum ETH purchased.

　　param deadline Time after which this transaction can no longer be executed.

　　param recipient The address that receives output ETH.
