100 million to 1 billion is a lot of agents! It depends on the =
complexity of the agents themselves, but you usually need a rather large =
computer to meaningfully model this type of thing in any form. I =
certainly would not recommend starting at this scale! You might start =
with Repast using smaller numbers of agents then move towards =
increasingly customized code as you scale up.

In terms of agent locations, it again depends on what you intend. =
Broadly speaking, models only require explicit spatial locations for =
components if the agent behavior or output analysis depends on explicit =
spatial locations. For example, modelers sometimes use networks in place =
of explicit spatial locations since for some models only the relative =
connectivity is important, as opposed to exact lattitude and longitude.

2 questions about building large-scale ABMs with Repast:

Can Repast be used to build models with 100 million to 1 billion agents
(think India)?

Can Repast build ABMs where the location of every single school, house, =
and
work are not explicitly known (clearly not possible in the case of a =
region
as big as India).
