I would like to make 3 announcements:
1. We just updated and expanded our “EcoSwarm” library of Objective-C
classes that support ecological (and other) modeling in Swarm. See
http://www.humboldt.edu/~ecomodel/software.htm
EcoSwarm now includes:
o BreakoutReporter: provides statistical summaries of agent state,
broken out by up to 5 categories.
o InterpolationTable: A lookup table and interpolation function.
o SolarManager: Calculates day lengths and solar radiation influx.
o SurvivalProbabilityManager: Builds probabilistic models of survival,
for mortality risks that vary with characteristics of both agents and
habitat.
o TimeManager: Provides many handy date & time functions.
o TimeSeriesInputManager: Reads in and manages time-series input data.
o YearShuffler: Randomly re-orders the sequence of years in time-series
input to a model.
o Poisson, binomial distributions: Integer random distributions (which
will be included in Swarm’s random library in the upcoming new release
of Swarm).
2. We (Humboldt State University’s mathematical modeling program) will
host the 2005 World Conference on Natural Resource Modeling, June 14 to
17, here in the beautiful redwood coast of northern California. Anyone
interested in organizing or contributing to sessions (or other special
events) related to agent-based simulation to contact me, or the official
organizer, Dr. Roland Lamberson address@hidden .
The 2006 conference will be in Bergen, Norway, another hotbed of
individual-based modeling. We hope this series becomes a home for
agent-based simulation in natural resource-related (including economic
as well as ecological) modeling.
3. The book “Individual-based Modeling and Ecology” by Volker Grimm and
Steve Railsback is now in production at Princeton University Press. We
provide a primer on modeling, a conceptual foundation for
individual-based modeling, an approach to theory and its development,
guidance on many practical issues, and many example models and
applications. I hope the book can be quite useful to people working in
fields other than ecology, as well.
Unfortunately, the book is unlikely to be officially available until
next summer. We put some example text on a web site
http://www.humboldt.edu/~ecomodel/book.htm and encourage people to
contact us for more information.
