Re: [FRIAM] Classification of ABM's

Phylogenetic trees and cladistics are useful to understand any evolutionary or complex adaptive system. I am not sure if a phylogenetic tree for ABMs itself makes sense. Of course we can try to categorize them by a taxonomy. On the NetLogo models pages we find the following categories: * Art

2009-01-04 Thread Jack K. Horner
Here's my ruble's worth on the cladistics and related questions: 1. For at least 30 years, there has been a feud in the biological cladistics community about whether cladistics should or does concern itself with history/evolution. If you enjoy a good shouting match, peruse the

I'm afraid taxonomy, mentally encapsulated or otherwise, has little to do with the way I develop an ABM, Nick. Rather, good software engineering practices provide the tools for success. CMMI provides a reasonable software engineering methodology that emphasizes feedback between the following

Jim, I cheerfully concede that one is free to view the universe or any of its subcomponents through an astoundingly large variety of frames of reference (FOR). Whichever FOR best gets a person through the day is the one that should be used. As a not-so-extreme example, an acquaintance of mine

Steverino, I guess it depends on what your definitions of trees vs. forests are, as pertains to my particular interest areas. In order to develop a viable set of requirements for any given simulation project, one must be able to perceive the top level view, as well as being capable of

Doug - On the other hand, top (top, top, top) level views which result in such profound observations such as Order matters, or Complexity is, or Taxonomies exist rarely hold much interest for me, unless they make the job of designing functional complex systems easier.
