In this thesis, Binary PSO has been analyzed through bit change rate, velocity expected value and genetic algorithm pattern theory.
本文从位改变率、速度的期望值及遗传算法模式概念等三个方面对其进行分析。 本文得到:二进制PSO算法不收敛于群体最优粒子,其位值随着迭代运行而越来越随机。

N the sum or integral of all possible values of a random variable, or any given function of it, multiplied by the respective probabilities of the values of the variable. Symbol: E(X). E(X) is the mean of the distribution; E(X–c) = E(X)–c where c is a constant 数学期望值 (Also called mathematical expectation) [statistics]
Since this is a concave function, it's not just the expected value.
由于这是一个凹函数,它不仅仅是期望值。
Although unwieldy, this does correctly match the predicate on the server and return the expected value.
虽然有些笨拙,但是这的确能正确地匹配服务器上的谓词,并返回预期的值。
Depending on what the expected value is, that could be trillionths or it could be millions.
根据期望值不同,这个值可以是万亿分之一,也可以是数百万。
Another important concept in probability theory that we will use a lot is expected value, the mean, or average-- those are all roughly interchangeable concepts.
概率论中另外一个常用的重要的概念是,期望值或者也叫均值,这两个概念可以互换
The basic definition-- the expected value of some random variable x--E--I guess I should have said that a random variable is a quantity that takes on value.
