Software

There is no software explicitly for FURM. FURM is a method by which models are created. The only software associated with FURM so far is the code for the ISL models and the experimental apparatus in which they sit.

Downloads

The ISL software will is not yet available for download.

Documentation

The only documentation we have so far is the content of our Technical Report and submitted papers, available in the Documents section.

However, below are some UML-ish diagrams that help explain the structure of the software. These diagrams have been purposefully simplified to get across the primary structure of the system.

Main Class Diagram

This is the class diagram for the experiment level of the ISL. This is the level at which experiments are set up, controlled, and logged.

Reference Model Inheritance Diagram

This shows the rather simple inheritance relationships used in the RefModel. The simplicity of this diagram is not really deceiving because this model really is just a simple mathematical function evaluated at each time step.

Articulated Model Inheritance

The ArtModel is clearly the most complicated component of the ISL. When looking at this and the subsequent constituents diagrams, refer to the description of the modelon the ISL page.

Articulated Model Constituents

This diagram lists the classes whose objects participate in the evaluation of the ArtModel. It indicates run-time composition.

Model Utilities Inheritance

The model utilities are miscellaneous things we had to create to augment the Swarm framework to support the ISL. Other ABM packages have analogues to many of these components and when the ISL is ported to another platform, this package is expected to change accordingly.

Graph Package Inheritance

This is a modified version of a directed graph library contribution to Swarm. There are a number of changes we made to the API and we added some extra functionality. But, the structure is the same.

Local Random Constituents

These are a few random number distributions are provided in the global scope for use in the various models. They're "local" to the ISL and distinct from the default distributions provided by Swarm.

Notes

• The ISL is written using a combination of Objective-C and C++. Hence, the elements of these diagrams do not translate as directly as they would to Java.
• We are in the process of making several extensions to the model, including adding enzyme induction and elimination. So, these diagrams are already slightly out-of-date. But, there should be enough here to present the gist.
• The GML (Graph Modeling Language) class is just an abstraction allowing the ArtModel to read the directed graph of sinusoidal segments from a GML file. It's not clear that GML is the best format for this application; but, it is much more self-descriptive than a simple adjacency matrix and it can include visualization information. We intend to add visualization in the near future. In the meantime, we manipulate the graphs with tools like Tulip and GVF.
• We also have a lobule architecture specific parametrized way of specifying graphs called the LobuleSpec in the form of a matrix with the following structure:

  Zone I nodes	Zone II nodes	Zone III nodes
  I->I edges	I->II edges	I->III edges
  II->I edges	II->II edges	II->III edges
  III->I edges	III->II edges	III->III edges
