LOGO-L> volterra-lotka again

[neuwirth <neuwirth@smc.univie.ac.at>]

hello predators and prey,

george, of course you are right,
your way of modeling this problem is
completely different from the volterra-lotka
approach, because you are nuot just looking at
the total numbers but also use spatial distribution.
essentially, what you are doing is modeling the system
with cellular automata.

i quoted you (partially out of context, as you said)
because the way the volterra-lotka model
is written for calculation purposes
usually makes it very difficult to
understand what the parameters really indicate.

the way of writing the model i suggested
makes it easier to see the connection between
the model parameters and the model behavior.

and you said something about difficulties is
finding "the right" model parameters.
and then i simply could not resist quoting you.
