I'm considering the development of an ABM in which the agents are charged
for the computations they do. But I can't think of a language that
facilitates that. I know that in most languages one can look at the
real-time clock, but I can't think of a language in which one can look at a
dynamic
Interesting idea. Most Common Lisp implementations compile to native machine
code, so it might not be too hard to instrument the generated code to do some
kind of bookeeping. There are quite a few open source implementations out
there, e.g. Steel Bank Common Lisp (www.sbcl.org) or Clozure
Yes, as always, Steve is correct. In my 1971 paper I included some stability
calculations indicating that for a flyer moving ahead of the Vee line things
became tougher, and vice versa.
The funny thing, as noted in that paper, was that the lead bird, at the apex of
the Vee, had the easiest
Hey Russ,
You might look at how Google App Engine tries to get a handle on this
when charging for CPU:

Josh has pointed out that there's some weird interpretations. For
instance, they quote $0.10 per cpu hour but don't specify the CPU. Is

I'm curious to know if there is much work showing the relative strengths of the
birds and their proportionate times spent in various positions. For example,
intuitively one might expect that weaker birds would actually take the easiest
positions for longer durations (contrary to the
Alas, fundamental principles in animal behavior still tell us that animals
should act selfishly. For selection to favor weakest individual willing to be
in the hardest position, it only has to be the case that being in the hardest
position in a group is still better than being alone. The reason we

One problem with that, as I see it, is that a weak bird ending up in the
hardest position simply cannot sustain it if the strongest bird in the easiest
position pushes the pace to its sustainable maximum. At some point, sooner or
later, the weak bird will fall off from exhaustion. However, if
Thanks, Stephen. How come you only post announcements to Friam?
About Google, they have an advantage over my situation. They can start and
stop the clock when they start and stop the application. I don't know that I
can do that for agents. Also, I have no control over whether something else
