Hey there , i think this cf round overlaps with topcoder srm ;)
i just wanted to point it out , no hard feelings, just in case it can be re-scheduled.
I am looking for help regarding the "Minimum vertex cover" of a bipartite graph.
A vertex cove of a graph is a set of vertices such that each edge of the graph is incident to at least one vertex of the set.
I know that its equal to the maximum matching , acording to Konig theorem .
I want to know how to find it (find the nodes) ;
I've seen some explanations on the internet but they all seem very hard to understand (a lot of mathematical notations, wich are bugging me ) .
All ive understood is that you somehow have to start from a maximum match , then apply some greedy algorithm wich i don't understand.
Can some1 explain it to me in an intuitive manner please :D
Hello everyone , I am seeking help regarding interactive tasks (IOI-style alike).
I want to get used to this type of problems , but can't seem to find any website that supports interactive submisions.
Also sharing with me some nice interactive tasks that you know of would be of great help .
Thanks a lot!!!, All the best !!!

Hey , my name is Dutzu ,I'm 17 and I am searching for a friendly group of people who want to simulate ACM-like contests . I'm not preparing for ACM , I'm just doing it for fun. I think working in team is more productive than training alone. I'm usualy free after 17:00 (Romania time) http://www.timeanddate.com/worldclock/fixedtime.html?iso=20140526T17&p1=2210 ,but I got no fixed schendule and also summer holiday is coming soon. My algorithmic level is alike my codeforces rating.
$$$ Have a nice day !
