I'm curious what you are trying to model that requires 10^15 agents.

Doug,
Some short answers, we can discuss further some time if
interested.
First: the technical reasons C++ was not considered OO =
strong typing, friend declarations, multiple inheritance,
explicit constructors, and an over-dependence on function
overrides.
Second: subtler, but in my opinion
Hey, thanks Dave.
A couple of comments:
In contrast - the OO tradition that began with Simula (not Simula I which
was already moving away from the philosophical ideal) and was embodied in
Self and Smalltalk, did not care about the machine, did not care about
efficiency, it was all about

Actually, this exchange is more useful to me than most I've seen on
this topic.
As usual, I understand both sides of the argument and agree with
neither!
Or to be contrary, I agree with both. I appreciate the elegance of
representation that well-designed

Therefore, 100% faithfulness of representation of the physical system

I don't disagree with any of that, Marcus. I do feel compelled to point out
that garbage collectors are extremely heavy weight language components, and
are one of the features of Java that prevent it from competing with C++ for
large-scale computational efficiency.

Hey, as IB, I would like to point out that biological models make
sense because we are unavoidably biological in design, thus our
systems will be. All our systems: interpretive, expressive,
diagnostic, experimental. No matter how far we think we may evolve
past that, we cannot. We just

Ok, so now that we have our trip down OOP Memory Land out of the way, a few
questions:
1) What are the agents in this 1.0E^6 agent simulation?
