Center node: "ecolab agent based modeling for c programmers"
  Abstract: AbstractEcoLab is an agent based modeling system for C++ programmers,strongly inﬂuenced by the design of Swarm. This paper is just a briefoutline of EcoLab’s features, more details can be found in other publishedarticles, documentation and source code from the EcoLab website. 1 EcoLab EcoLab is an ABM system for C++ programmers. This is not the time or placeto debate the merits of C++ over any other object oriented language. If youhave chosen C++ as an implementation language for your models because ofperformance, expressibility, familiarity or compatibility with other software li-braries, then ABM environments such as Swarm or Repast oﬀer little supportto you. In this case, you should consider EcoLab. 2 Scripting EcoLab uses the Classdesc[2] object descriptor technology. This provides a formof object reﬂection, or the ability to query an object’s internal structure atruntime. This may seem obvious to a Java or Objective C programmer, asobject reﬂection is built into the language.How is Classdesc used in EcoLab? The user codes their entire model as a class.Usually, there will only be one instantiated object of that class (the model).Mostmodel instancevariables, andmodel methods adheringto particularcallingconventions are exposed to a TCL interpreter. This allows great ﬂexibility to1
