In this code only so will appear JavaScript cue box is garbled, the main reason is in the Java output stream. The ISO-8859-1 code is adopted. This is not a problem for Java programs, if you do not embed Jav
This article undertakes the previous article, mainly explains the Ford-fulkerson solution of the maximal flow problem. However, this is a method, not an algorithm, because it contains several implementations with different run times. The method relies on three important ideas: residual networks, augmented paths and cuts. This article will cover this in more detail, and we'll provide a Java implementation of this approach in the next article.
Before in
First, the characteristics of the greedy algorithmAs the name implies, the greedy algorithm always makes the best choice in the current view. Although the greedy algorithm is not considered from the overall optimal, the choice made by it is only a partial optimal choice in some sense.The advantage of greedy algorithm is simpler, more direct and more efficient, even if the greedy algorithm can not get the whole optimal solution, but the final result is a good approximate solution of the optimal s
The use of Windows operating system will inevitably encounter some trouble for the user to touch the mind, in the Windows7 system, there is a problem step recorder function, can be a detailed record of the occurrence of the problem, the user can grasp the failure of the process, easy to find the problem, To solve the problem
Recently in doing a project, encountered Ajax Chinese garbled problem, after an afternoon's efforts to finally perfect solution, now will write down the experience, I hope that those who are still trapped in this problem and headache people have helped.
As we all know, the use of Ajax to send and receive Chinese parameters, if not the client and the server to do the corresponding processing will appear

In the process of daily project development and implementation, there will be a series of problems and tasks around the system, such as requirements, defects, suggestions, and tasks. In the context of systematic development of work information, generally, a unified problem tracking platform is used to record, track, and manage various problems, such as Jira and ITSM. The appendix summarizes and standardizes the problems I encountered during the early
First of all, declare that QString is not a Chinese support problem, many people encounter problems, not their own QString problem, but not the string they want to correctly assign to QString.The simple question, "I'm Chinese", is that it's a narrow string of traditional char types, and all we need is just one way of telling qstring the code used in these four characters. And the

Problem Description
UESTC Department Canteen's rice card has a very strange design, that is, before the purchase to determine the balance. If the remaining amount on the card is greater than or equal to 5 yuan before the purchase of an item, the purchase must be successful (even if the balance is negative on the card after purchase), it cannot be purchased (even if the amount is sufficient). So we all want to try to keep the

The problem of the maximum matching of binary graphs the first one has said, the following look at Baidu Encyclopedia to give some explanations:
Given a binary graph g,m as a subset of the G-side set, M is a match if any of the two edges of the M-satisfies are not attached to the same vertex.
A maximum match (maximal Matching) is the number of matching edges that can no longer be added by adding an incomplete matching edge, under the currently compl
