XCS Project Home

Changes:

• Updated README to point to the HTML version of the tutorial on pythonhosted.org
• Interface change - situation tracking
  • Added situation argument to ActionSet.__init__()
  • Added situation property to ActionSet
  • Removed now unnecessary situation argument to LCSAlgorithm.update()
• Added BitString.random() to allow numpy to be used in bitwise mutations
  when it is available.
• Added BitString.crossover_template() to allow numpy to be used in bit
  condition crossover when available.
• Added initialization from ordinary strings to __init__ methods of BitString and BitCondition
• Added the ability to detect and switch between numpy versus pure Python BitString
  implementations.
• Fixed a bug in BitString.__getitem__ in both implementations which was
  causing the underlying array type to leak through when using slices.
• Added the abstract reset() method to OnLineProblem, and implemented it
  for each problem class.
• Added the HaystackProblem, which requires the algorithm to search for a
  single relevant bit among a large set of irrelevant ones.
• Fixed a bug where the wildcard probability was being inverted in the
  BitCondition.cover() method.
• Renamed the tutorial to XCSTutorial
• Added new section to the tutorial, Defining New Problem Types
