public class ExpandingPopulation
extends ExponentialGrowth
implements Report, Parameterized, java.io.Serializable
```
This class models a population that grows exponentially from an inital population size alpha N0 to a present-day size N0. (Parameters: N0=present-day population size; r=growth rate; alpha: ratio of population sizes). This model is nested with the exponential-growth model (alpha -> 0).
