Web粒子群优化（Particle Swarm Optimization, PSO）是一种基于群体智能的优化算法，由Eberhart和Kennedy在1995年提出。. 该算法模拟了鸟群或鱼群等自然群体的行为，通过不断调整每个粒子的速度和位置来搜索最优解。. 在PSO中，每个粒子代表一个潜在的解，其状态 … WebSep 26, 2015 · To generate a random number use the rand () function of the math library (so include ). The rand function will generate a random number within a large range. However, you can convert this large number to a number from 0-3 by taking the modulus with 4.
