    说明:  为了处理快速变化的动态环境,在微粒速度更新公式中增加了一项变化项,从而无需检测环境的变化就可以跟踪环境。尽管该方面的研究成果至今较少,但不容质疑这是一项重要的研究内容(To deal with the rapidly changing dynamic environment, update the formula in the particle velocity increased by a change in key, so no need to detect changes in the environment can track the environment. Although the results of research so far less, but no question this is an important research)

    说明:  首先介绍一下早期的简单模型,即Boid(Bird-oid)模型。这个模型是为了模拟鸟群的行为而设计的,它也是粒子群优化算法的直接来源。(Because the simulation is too simple and far away from the real situation, a random variable is added to the velocity term, that is, in each iteration step, in addition to meeting the "nearest neighbor velocity matching", a random variable is added to each step of the speed, so that the whole simulation looks more realistic.)
