Poj 1149 (maximum flow chart)Title: There are M pigsty, n customers, n customers arrive sequentially, each customer can open a number of pigsty, you can choose to sell to the current customer not more than B pig, and the current open pig in the pigsty can be arbitrarily adjusted. Ask how many pigs can be sold.Idea: The first is the intuitive building, because there are sequential relationships, so consider to each customer to build a layer of graph, then the number of nodes is NXM, this number i

How to use PHP programs to develop efficient WEB network systems. PHP is an excellent tool, which can be simple or complex. Different projects should use different PHP. Small Projects-simple and direct PHP is generally an excellent tool for a functional page of PHP, which can be simple or complex. Different projects should use different PHP. Small Project-simple and direct PHP For a website with a function page under 20, we can use a simple framew

Triggering an event in multiple threads may throw an exception with the reference being null. This issue is discussed on the Internet many times. The NetworkComms communication framework has almost no use events, so this issue does not exist in the core communication f

First of all, I downloaded from the Web Application Network (http://www.webasp.net) to the five-star "Golden Disk E-government System" source program. A big company is good. Next, how do I install, debug it. The reason for writing this document is because many of the source code downloaded on the Internet do not have enough installation and debugging instructions. The same is true for this system. Anyway, u
