旅行商问题
某售货员要到若干城市去推销商品,已知各城市之间的路程(或旅费)。他要选定一条从驻地出发,经过每个城市一遍,最后回到驻地的路线,使总的路程(或旅费)最小。
例如:给定4个城市{1,2,3,4}及其各城市之间的路程
最优路线是1,3,2,4,1,
其最短路程是25-a salesman, traveling salesman problem, a number of cities to sell commodities, the known distance between the city (or travel). He selected from a resident, after each city again, the last resident to return to the line, making the total distance (or travel) is the smallest. For example : given four cities (1,2,3,4) and the distance between the city optimal route is 1,3,2,4, 1, the shortest distance is 25

Sicily 1009梅森素数
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.
