Xholon is a flexible open source tool for multi-paradigm (UML 2, ABM, SBML, NN, GP, PSys, CA, ...) modeling, simulation, design, execution, and transformation. Generic Java and XML building blocks are extended into multiple domains and woven into loosely organized systems.


UML state machine simulation capabilities have been extended, including animation, and fork, join, junction. Additional Agent-Based Modeling functionality is available. The NetLogo-like syntax has been enhanced. The architecture is more flexible and is ready to more fully support integration of multiple domains. Histograms and probability distributions are now available. Line charts update in real-time. Numerous other modeling, simulation, transformation, and execution features have been added.
