We already know that UCBAlgorithmWe can quickly find a reliable starting point and continue the previous article. Can we optimize it? First, we need to know why the UCB algorithm converges faster than the blind Monte Carlo evaluation?In my understanding, the reason is that during the Algorithm Execution Process, The UCB algorithm can constantly adjust the policy based on the previous results and select wh

Recent projects need to fetch from the network data parsing HTML source code, but the regular expression is difficult to write, so the online search found the "Htmlagilitypack" class library, agile development, really efficient and extraordinary.Take notes here, write down your thoughts, and summarize them by the way.1, htmlagilitypack using XPath for path search, if you are familiar with XML path search, it will be handy to use.XML version= "1.0" encoding= "Iso-8859-1"?>

The development requirement of Asp.net is that the user control (UserControl) is integrated with a function. The data to be processed must be stored in the database and displayed on the webpage, so that the user can detect the data to be processed. In this demonstration, Insus.
