  +--physis.core.Population

public class Population

extends java.lang.Object

Population class represents the whole population running in one concrete instance of the system. When the system is distributed through the network it represents all the digital organisms living on the same node.
CRC
1. does the updates of organism - Scheduler
2. after each update it refreshes the state of the population described by state variables.
