Short description
JAS is a Java toolkit for creating agent-based simulations.
It features a discrete-event time engine, statistical probes with Hypersonic database built-in storage capability, Neural Networks and Genetic Algorithms packages, graph support for Social Netwok Analysis.
Main features
  • Discrete-event time simulation engine.
  • A custom Java class-loader loads models without the CLASSPATH variable configuration.
  • Different time unit management (ticks, seconds, minutes, days...).
  • The real time engine is able to fire events using the real computer timer. Useful for emulation models.
  • Support for XML data I/O and SVG file format.
  • Genetic algorithms, neural networks, (classifier systems, still under construction).
  • Sim2Web: a JAS-Zope bridge for web publishing of simulations and remote users interaction.
  • The MultiRun class manages looped model run for automatic parameters calibration.
  • The statistical package, based on the cern.jet package, with file and database I/O features.
  • Hypersonic database is built-in the JAS package.
  • The brand new jas.graph package allows to manage relational agents, with native Social Network Analysis computing.
