GŁnther,

Thanks for your input and for considering MASON. As our documentation says
(Luke et al. 2005), you should consider MASON if you need:
-replicability guarantee
-computational and visualization separation for
-lots of runs (>10^3) without viz every run ;-)
-checkpointing for stats analysis
-evolutionary computational methods, as common for assessing learning.

Perhaps these performance features fit your project on cultural diffusion
modeling.

Tony Bigbee wrote the most complete replication of Sugarscape, which the
three of us (Bigbee, Cioffi, Luke 2005) presented as a paper at the ESSA
meeting last year in Koblenz. We will make sure to send you the revised
paper as we develop it. MASON Sugarscape implements many more rules than
previous models, such as those in Repast, Netlogo. Both Epstein and Axtell
(now at our Center, no longer Brookings) provided input.

Alles gut

Claudio
