Hi,

The use of multipopulation for AG algolithma is often introduced to avoid the problem of premature covergence by dividing the population into several subpopulations.

For more details and information about this subject, I suggest you see the links on the topic.

There is no theory about population size. In most cases, population size is determined experimentally. A bigger single population is not better than a group of populations.
