Description
  • For groups of animals to keep together, the group members have to perform switches between two types of behaviours (staying in one place or moving to another place) in synchrony ([1]). However, synchronization imposes a cost on individual animal, because animal is trying to keep its ideal switch time point that is generally not equal to common time of synchronization. We suppose that each animal is defined by this individual ideal switch time. The distribution of ideal time points is derived from normal distribution with zero mean. The density function is positive on finite interval (-1, 1). Maximization of individual benefit across the parameter space results in three types of optimal behaviours: 1) Non-synchronized switch - that defines individual switch independent on the group of animals. Switch points are ideal individual points. 2) Totally synchronized switch - all animals in the group are synchronized. 3) Partially synchronized switch - only the part of the group is synchronized ([2]). In the context of the degree of synchronization the splitting of the group is very important ([3], [4]). In the case of partially synchronized switch the non-synchronized rest of the group will stay in place. The first question is concerned in the comparison of the benefits for one and two partially synchronized switches. We analysed this problem for simplified symmetric case. Here the benefit for one switch is higher. After it we concentrated on the problem of the second departure of the rest of the group of animals and on possible stabilization of the group size.
