Minimum Build forest? Personal feeling is similar to the smallest spanning tree. Need to be divided into K-link block, so that the maximum distance between the Unicom block so that the distance between the block as small as possible. A minimum spanning tree is a N-1 bar, divided into K blocks need to cut k-1 bar, is a n-k edge of the smallest generation forest, and then kruskal the next Edge (section n-k+2) is the answer.#include #include#include#include#include#include#includetypedefLong LongLL

Welcome to the original source-- Blog Park-zhouzhendong go to the blog Park to see the puzzleTopic Portal-BZOJ1821Test Instructions SummaryThere are n points on the plane, and now they are divided into K parts to find the maximum of the nearest distance between the different parts.The distance between the two parts is the nearest point pair in the two section.n SolvingWe have all the points built on the side.Then we have to update the answer, we should try to get rid of the short side.So I star

I am ZZ, so simple to write wrong ...One eye two points, then judge the word is the enumeration point, and then calculate the point to the existing Unicom block of the minimum distance, if this point to some of the Unicom block distance is less than the current two-point Val, then the integration of these unicom blocks, here with and check the set maintenance, and finally see if the number of tribes is greater than KThere is a very small optimization is not double two points, directly to the poi
