Jenetics: Java Genetic Algorithm Library / News: Recent posts

The SVN repository has been migrated to Mercurial. To clone the repository call

hg clone http://hg.code.sf.net/p/jenetics/main jenetics-main

• The PropabilitySelector no longer sorts the population before calling the
  ProbabilitySelector.probabilities() method. The subclass must sort the
  population if needed.
• Move Verifiyble interface to util package.
• Change signature of the Alterer.alter(Population, int) method. Adding the
  generation of the altered phenotype.
• Add new abstract Alterer class Recombination.
• Move RandomRegistry into org.jenetics.util package.
• Add org.jenetics.util.EvaluatorRegistry class.
• Parallelize the recombination in the Recombination class.

Adding concurrent support on the fitness calculation level. New classes are ConcurrentEvaluator and ThreadedEvaluator.

• Adding javadoc to exported zip file.
• Moving classes
  • Array
  • ArrayIterator
  • ArrayUtils
  • BitUtils
  • Probability
  • Validator
    into new org.jenetics.util package.
• Changing interface 'FitnessFunction'. It converts a given Genotyp<G> to an
  (more general) java.lang.Comparable instead of a double value. An additional
  generic parameter (C extends Comparable<C>) was therefor introduced in the
  FitnessScaler, Phenotype, Population, Selector and GeneticAlgorithm class.
• Adding NumericStatistic and NumericStatisticCalculator. Move functionality
  from old Statistic class into the new NumericStatistic class.
• Some additional helper methods in the ArrayUtils class.
• Remove method CharacterGene.getCharacter(), use CharacterGene.getAllele()
  instead.
• adding interface org.jenetics.util.Copyable.
• Streamline XML-Serialization.
• Streamline toString methods and examples.

• Removing Randomizable interface.
• Changing the template method return value of the
  ProbabilitySelector.probabilities(Population<T>,int) from
  Probabilities[] to double[].
• Replace array types (e.g. IntegerGene[]) with Array<T> class
  (e.g. Array<IntegerGene>). This moves all the 'unchecked' stuff in the new
  Array class.
• Only add valid phenotypes to surviving phenotypes.
• Caching the isValid value in AbstractChromosome and Genotype.
• Rename util class org.jenetics.Arrays to org.jenetics.ArrayUtils.
• Adding StatisticTest class.
• Adding the (shortcut)method Genotype.getGene()
• Adding the method Chromosome.getGene() to the Chromosome interface.
• Adding the ConcurrentStatisticCalculator class.
• Making the StatisticsCalculator class public.

At last I did the first checkin in the CVS repository. This was also a good opportunity to build a new version with a view bug fixes.

New maintenance version.

In this version the ant build script has been improved and a couple of unit tests (TestNG) has been added.

New version with bug fixes in the Integer- and DoubleChromosome class. The package now contains an Ant build file and compile instructions.
