摘要：The concept of self-propelled particles is used to study the collective motion of different organisms such as flocking of birds, swimming of schools of fish or migrating of bacteria. The collective motion of self-propelled particles is investigated in the presence of obstacles and without obstacles. A comparison of the effects of interaction radius, speed and noise on the collective motion of self-propelled particles is conducted. It is found that in the presence of obstacles, mean square displacement of the particles shows large fluctuation, whereas without obstacles fluctuation is less. It is also shown that in the presence of the obstacles, an optimal noise, which maximizes the collective motion of the particles, exists
