New feature release

This release contains following major changes:

• Added decision-making feature module
• Added aspiration adaptation strategy as "fast-and-frugal" decision heuristic
• Added example for mutli-goal optimization (Fonseca-Fleming problem) to demonstrate heuristic

Minor correction and changes to other parts of the code.

New feature release

This release contains following major changes:

• Individual agents can be monitored during the simulation run with an InstrumentationDecorator.
• Instrumentation added to Elevator example, additional explanation added
• Interfaces added for core entities (ModelEntity, Agent, Domain, Port).
• Naming consistency: Basic classes implement basic functionality of the coressponding interfaces (Abtract changed to Basic).
• Visibility of some methods adjusted

Production Release with minor improvements

This release contains following improvements:

• Optimization of some event queues (MulitLevel, HashBucket, HeapBucket)
• Additional performance test for large event queues (>100k events) and repeated usage

Feel free to drop me a comment !

Production Release

This release contains the jsimplesim simulation framework with complete and testet functionality. The instructive example of an elevator control simulation was added to illustrate agent-building and to compare a static and dynamic modeling approach. Documentation was improved, too.

Changes to last release:

• Logging to stream functionality added to AbstractBasicAgent
• Class Message substitutes DirectMessage (deprecated)
• Utility methods added to Time class
• Minor improvements to javadoc

Dynamic model changes and a new example

This release adds the following feature:

• dynamic model changes during a simulation run via change requests
• simulation of an elevator as new example using
  a) a static model
  b) a dynamic model and change requests

Develoment of the framework is finished at this point. Please feel free to experiement and report any bugs, issues or ideas for improvement to jsimplesim@simnation.org

Please see https://simnation.org for a tutorial and documentation.

Initial release

JSimpleSim is a framework to build multi-agent simulation systems in a quick and easy way. It features:

• simple agent model to be easily extended for your needs
• efficient messaging system
• various simulators (single- and mulit-threaded, discrete-event and time-step)

This software is published as open source and licensed under the terms of GNU GPLv3.
