4.2 Our main results can be summarized as follows. In the absence of a leader and without communication, small groups perform better than large ones. Large groups explore the environment more widely than smaller ones. As a result the first individual to discover the target takes less time than in a small group. But in small groups the last individual to discover and reach the target takes less time than in large groups. Given the collective nature of the task it is this time that determines the performance of the group.
4.3 In the absence of communication, the addition of a leader—an individual that can partially dictate the way the group moves in the environment—has a beneficial effect on group performance. The presence of a leader causes the group to explore the environment as a group, so that when one individual discovers the target the other individuals are close by. Hence, large groups benefit more than small ones.

4.2我们主要的结论可以总结如下：在主导者不存在并且没有通信的情况下，小的

法，有益于群组的表现。主导者的存在使群组作为一个群体去探测环境，所以，

当一个个体发现了目标其它的个体其它的个体就在附近，因此，大的群组在这方

面就比小的群组有益。
