Integrating Modelling Toolkit. The Integrating Modelling Toolkit (IMT) is a generic, comprehensive, and extensible set of abstractions allowing definition and use of interoperable XML-specified model components. It is being developed by Ferdinando Villa of the Institute for Ecological Economics, University of Maryland.

Marcus Daniels has a description of the prototype IMT (Layer 1) with some discussion of potential integration with Swarm as part of the An open framework for agent-based modeling paper delivered at LANL in April 2000.

It also has a sourceforge site

Multi-Agent Modeling Language (MAML). The current version of MAML is basically an extension to Objective C (using the Swarm libraries). It consists of a couple of `macro-keywords' that define the general structure of a simulation. The remaining must be filled with pure swarm-code. A MAML-to-Swarm (named xmc) compiler is also being developed which compiles the source code into a swarm application. Like every other Swarm application, this generated application must be compiled by gcc.

Swarm versions 2.1.1, 1.4.1, 1.3 and 1.0.2 are currently supported.

Evo.  is a software development framework built on top of Swarm that allows developers to build complex alife simulations. Using Evo, researchers can easily build systems of independent agents interacting with one another and with their environment. Evo implements biological operators such as genetic recombination and mutation to evolve the behavior of agents so that they are more adapted to their environment. Evo is similar to genetic programming (GP) in the sense that the genome of an individual agent is a program that is executed. The Evo framework handles the generation and execution of these genomes within the environment specified by the developer. Analysis tools allow the developer to see how the gene pool of a population changes over time, and how individual agents are genetically related to other agents in the population. Evo includes several example simulations to get developers started, as well as a comprehensive programmer's guide and API reference.
