of Optimization Measures for most client-server communications. Install one of the two as the reverse proxy (reverseProxy, which is explained in the Server Load balancer section below) can greatly improve the performance of the web server and reduce the workload required to process requests from the client.

is a collision. Because the direction of food is fixed, we can easily find all the easy-to-Master time for each bag of food in its "Forward" direction (the number of easy-to-Master times equals the number of "passes" times in expansion 2 ). In this way, our problem is equivalent:
Find the minimum time t, so that the frequency of the master is greater than or equal to K if the master is less than or equal to T.
Because all collision (easy-to-Master) Time is the whole point, we can use two
