OpenAI Gym is a toolkit for developing and comparing RL algorithms that is compatible with other numerical computing libraries, such as TensorFlow or Theano libraries. The Python language is now primarily supported and will be supported in other languages later. The gym document is in Https://gym.openai.com/docs.OpenAI Gym consists of 2 parts:1,

, and sometimes for learning, but formal evaluations do not allow this information to be used for learning.This is a typical implementation of the Agent-environment loop. Each time step, the Agent selects a action,environment to return a observation and reward.The process starts by calling reset, which returns an initial observation. So the more appropriate way to write the last blog code is to follow the complete logo:

Test Instructions: given an n, let you split it into the sum of a number of only 2 and 3, and there is no multiple relationship between 22, such as 10=4+6.idea: that is, the power of the 2 factor is incremented, the power of the 3 factor decreases, or vice versa.For the current n, we split the number to num=2^x*3^y; meet 2^x| N, and Y Max, and then continue splitting the n-num. Not difficult to launch, N-num is an even, and contains at least x+1 2 of the product, then the power of the N-num 2

Ideas:
Drawing can find the law, the worst case is that n points is a linear, then the time will be the longest, according to the linear law found that its length and time is twice times the increment, each new hour can be on the
