四阶龙格库塔法求解流体力学

应用背景In generated networks, selecting one node as source and some nodes as receivers in random (single source multicast network), we make performance test for network coding based multicast route algorithm (we put forward it ourselves, corresponding to high multicast rate and low multicast rate), shortest path distribution tree route algorithm (DIJKSTRA algorithm) and Maximum-rate distribution tree route algorithm (PRIM algorithm), respectively. 关键技术 In this program, two things have been done: (1) generate random topologies (2)performance test。   network coding cap:     5.0000  dijk cap:     5.0000  prim cap:     5.0000  network coding res1:     0.0000--res2:    12.0000  dijk res:    14.0000  prim res:    14.0000  average degree:     2.

One of the world-wide cooperative computing tasks is the "Grand Internet Mersenne Prime Search" -- GIMPS -- striving to find ever-larger prime numbers by examining a particular category of such numbers. A Mersenne number is defined as a number of the form (2p–1), where p is a prime number -- a number divisible only by one and itself. (A number that can be divided by numbers other than itself and one are called "composite" numbers, and each of these can be uniquely represented by the prime numbers that can be multiplied together to generate the composite number — referred to as its prime factors.) Initially it looks as though the Mersenne numbers are all primes. Prime Corresponding Mersenne Number 2 4–1 = 3 -- prime 3 8–1 = 7
