Marmara

• The Marmara archive includes the source code for the simulation environment with an example input file that specifies a population, a configuration file that sets the simulation parameters, a build.xml file to compile and run the code.
• The input file (.STATE) contains the initial state of the agents. The first line states how many agents the population has and how many dimensions expertise vectors have. Afterwards, you specify an expertise vector, an interest vector, and a set of neighbors for each agent. The configuration file (.conf) sets the thresholds, timeouts, and so on. There is a detailed description of each parameter in the appendix of pInar Yolum's dissertation on Emergent Properties of Referral Networks.
• The build.xml file will work with Jakarta ant. The simulation uses JBOSS implementation of Java Messaging Service. You need to install that separately. The build.xml file states where the JBOSS files should be installed. After the configuration, typing

  ant compile
  

  will compile the entire code and put the Java class files in the classes directory. Then, you run the code with

  ant run
  

  and four parameters. The first one is the .STATE file, the second is the .conf file, and the third is a directory name where the simulator will use for logging. The fourth parameter is the random seed and is optional. If you don't supply a seed, the simulator will use its own.
