中文说明：粒子群算法在离散优化领域的应用比较少见，为了将粒子群算法应用在QoS路由领域，而又不偏离粒子群算法的基本思想，定义并设计了一种“⊕算子”，并且设计了一种 “随机游动算子”，将基于路径的变异算子引入算法，增强算法的全局搜索能力。
English Description：
The application of particle swarm optimization in the field of discrete optimization is relatively rare. In order to apply particle swarm optimization in the field of QoS routing, and not deviate from the basic idea of particle swarm optimization, a "⊕ operator" is defined and designed, and a new algorithm is designed
