The following are the address：https://bbs.pinggu.org/thread-2194436-1-1.html；https://bbs.pinggu.org/thread-2192859-1-1.html
And in this question you've answerd( https://bbs.pinggu.org/thread-2179600-1-1.html),I have one question:how to understand the payoff in the text,which is Xi-XiT(X1+..+Xn).I think these two could not be minus because they are different.The Xi is the volume of transimitted data,the XiT is the time.The units of them are different.

Please be aware that the payoff function in the previous question is clearly given by the question, not created by me. So you might want to ask the person who made that question rather than me. Also, for the other two questions, I don't think they are clearly formulated. Sorry, I don’t fully understand those terminologies in Chinese. Hope others can help you with those two questions. Good luck.
