3. THE EXCESS SCALING ALGORITHM (正篇) 就是说咱们用了一个叫做excess scaling的技巧来把预流推进非饱和推流的次数从 优化到了 。基本思路是把拥有足够大超额流的节点往足够小超额流点推流,并保持这些超额流不要变得太大,咱们把这种算法叫做excess scaling algorithm(超额增量算法?) 本算法进行 次scaling,在每次...

It is not clear who originally came up with this elegant algorithm. One place it has been explained and used is [8]. Given a rotation system for a graph, a clockwise breadth-first search (BFS) starts at a specified root vertex r, and has a specified neighbor f of r designated to be...

Simple Security Definitions for and Constructions of 0-RTT Key Exchange 27 NIKE.Key(sk i, pk j) is a deterministic algorithm which takes as input a secret key sk i and a public key pk j, and outputs a key ki,j. We say that a NIKE scheme is correct, if for all (pk i, sk i)...
