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

粒子群算法在UPFC中的应用

资源描述根据货运量形成的原因，分析了货运量和相关影响因素之间的关系以及货运量预测的特点，在此基础上，建立货运量预测的广义回归神经网络(General Regression Neural Network,GRNN)模型，并以我国某年的货运量和相关经济指标的历史统计数据作为学习样本，通过拟合训练和外推预测分析，验证了GRNN用于货运量预测的有效性.
