Serie A championship: the task of assigning N m machine. To the number of days each task takes (if not ongoing daily) and can be done on which day tasks. Ask if there is a plan.The typical task (X)----Day (Y) Half of the maximum traffic (because this task is the relationship between days) of the processor control flow. SOURCE X Ministry of Foreign Affairs Point, it refers to a few days. Task Xi, in order to be able to do even if the day, Stream 1, a Y
"Problem Analysis"It is easy to think that it is best to put p on the edge of the maximum flow.So two-point network flow, determine when the maximum flow can be reached.Traffic is not necessarily an integer, so a real number is required, and the integer is WA.Code#include Bzoj 3130 [Sdoi2013] Cost Flow--network flow

Website traffic has always been the object of webmaster pursuit, because a website want to make money must be inseparable from the flow of support, no matter what the site, under certain conditions, the more traffic is the more benefits, so that the site to increase the flow of methods in addition to the use of SEO, but also can use other ways to But with the search engine algorithm constantly changing, the

Give the coordinates of the n block of ice, the number of penguins on each ice pack and the number of times they can withstand the jump, and ask what ice floe will bring the penguins together.
Analysis:
The limit of the point traffic is converted to the limit of the edge traffic, and the maximum flow is calculated.
Code:

Your task is to delete some of the contacts in some groups so that each contact is in only one group and the fewest number of people in the group. Find out the number of people in the group with the largest number.Title Analysis: Required is the smallest maximum, two-minute enumeration of this minimum maximum number of x.

Title: Give a graph with weights to find a minimum loop through the start S and end point T.Problem Analysis: Establish network, with S as the source point, T is the meeting point, and the capacity of each edge is 1, the unit cost is the edge weight value.
