常見例句雙語例句Settling laws of a swarm of particles in sediment-water mixture have been studied in this paper.本文探討了泥沙在渾水中的群體沉降規(guī)律。The algorithm discards the particle velocity and tracks the state of particle swarm by observing the overall changes in the fitness of all particles in the swarm.該算法舍棄了粒子速度這個參數(shù)，并通過粒子群中所有粒子適應度的整體變化跟蹤粒子群的狀態(tài)。On the basis of particle swarm optimization, an extended particle swarm optimization is first presented by replacing personal best particle with the average of personal best particles in swarm.在粒子群優(yōu)化算法的基礎上，首先把粒子群優(yōu)化算法的速度更新式中的個體最優(yōu)位置用粒子群中所有個體最優(yōu)位置的平均值代替，得到擴展粒子群優(yōu)化算法； 返回 swarm of particles
