• fixed bug in FcmIO.saveAsXml(): wrong schema version in XML output, uses 1.1 but should be 1.2;
• Refactored FcmIO.saveAsXml() to ToXmlVisitor.java

Version 1.4.0 is out. The most notable (and disrupting!) change is the new package structure:

• moved ConceptActivator and FcmConncetion implementations in sub-packages:
  • org.megadix.jfcm.act : ConceptActivator implementations;
  • org.megadix.jfcm.conn : FcmConnection implementations;

Moreover, Visitor design pattern was implemented to ease the development of serializers (XML, JSON, etc.), map analyzers, etc.

bugfix release

12 map.execute() should really have two phases

13 Add method CognitiveMap.reset() that resets every Concept to null

14 Create a deep copy constructor on CognitiveMap

2 XML output from FcmIO.saveAsXml() should include namespace

15 Backport LinearConceptActivator from 2.0-SNAPSHOT

7 Backport time delay to WeightedConnection from 2.0-SNAPSHOT

See Project Trac for details:

jfcm-jfuzzylogic has been committed to SVN!
This module enables fuzzy-powered activation rules for cognitive maps, and uses jfuzzylogic for fuzzy inference:

Major bugfixes, backwards compatible at API-level

I had the time to finally fix the most important bug in JFCM.
In short: calculation of concept outputs, up to version 1.0.3, was incorrect!
Now BaseConceptActivator.activate() uses a two steps algorithm:
- recalculates incoming connections' output;
- calculates Concept's output.

A new version has been released today: 1.0.3
It is a bugfix release, but many non-visible enhancements have bben carried out to source code:
- small bugfixes, no changes to APIs;
- better Maven-based reporting: Checkstyle, javadoc, PMD and, most important, Cobertura test coverage;
- all the Maven.generated html reports above are now published on the main website, in the Project Info page:
