PySwarms is an extensible research toolkit for particle swarm optimization (PSO) in Python. Plotting the cost history; Animating swarms. We will also learn the hands-on implementation of PSO using the python package PySwarms. Speed; Parallelism; Its flexible architecture enables you to define complex objective functions, and to perform optimization in a serial or parallel setting. In this case, the function is f(x,y) = x² + y² + 1. It takes a set of candidate solutions, and tries to find the best solution using a position-velocity update method. As its name suggests, these methods plot the particles in a 2-D or 3-D space. The first one is the class of a single particle, and the other class builds, given the single particle class as a builder, our swarm. Thus, the algorithm will work with 2 dimensions positions arrays From this we can call various methods already. Recall that we are using a Global-best PSO algorithm, where each particle compares itself with the best-performing 1、 学习代码源自:用python3实现粒子群优化算法(PSO)-by雨破尘 参考博文:[MATLAB] 经典智能算法1:粒子群优化算法PSO python粒子群算法的实现 by-winycg 此篇强推 粒子群优化算法(PSO)by森先生 2、算法思想 粒子运动思想(即鸟群捕食运动),同样是通过适应度来评 In summary, using the Particle Swarm Optimization (PSO) algorithm in Python is an effective and robust method for solving optimization problems.
