Where the sum goes over all pairs of types in the derivation plan such that to is the original type and TD the type derived from it and D (to, TD) is the distance of the Types 1/Σ (to, TD) D (to, TD) The derivative relationship has a directed

From http://www.fcicq.net/   Assume that you want to perform a series of search operations on a binary search tree. In order to make the entire search time shorter, those entries with high query frequency should always be near the root of the

Although ysy mentioned in the national team paperCodeThe complexity is low, but I personally think it is too long for ACM competitions. It is much better to write a treap, especially when only a slow binary tree is needed. A great cow told me that

"N This shape is basically the mark of State compression dp (a few hundred or so, a dozen or so ). One layer goes down to DP, and each layer is only affected by the first two layers. After calculation, each layer has a maximum of 60 States, and

A connected graph is provided. If you cut any edge and make the Graph Connected, add at least a few sides. As a result, the key edge is connected to a tree, and it is easy to prove that the edge at the leaf is the best. I read several articles
