Two species "prey-predator model" where the individuals purposefully migrate between two habitats is considered. A migration is regarded as transference from one habitat to another yielding in maximization of average (over two habitats) coefficient of reproduction. Targeted migration results in the increase in average abundance of population comparing with discrete analogies of classic equations of Volterra and also to the enlargement of the area of the admissible meanings of parameters. A great variety of dynamic regimes has been observed, some of them could be interpreted as outbreak explosion.
考虑了一种两个物种的“捕食-猎物模型”，其中个体在两个栖息地之间有目的地迁移。迁移被视为从一个栖息地转移到另一个栖息地，从而使（在两个栖息地之上的）平均繁殖系数最大化。与经典沃尔泰拉方程的离散类似情况相比，有针对性的迁移导致种群平均丰度增加，并且还扩大了参数允许取值范围的区域。已经观察到各种各样的动态状态，其中一些可以解释为爆发性增长。
